Tower crane which is the difference with other types of
Compared with other types of
overhead bridge crane in construction are very different . The main differences are: tower crane has a high vertical tower , the upper part of the tower is mounted crane jib , jib crane slewing part can do together with a 360 ° rotation .
This unique structure of the crane generation , primarily to meet the needs of construction . As we all know , for the construction crane construction services , should have the greatest possible lifting height to accommodate various types of tall buildings construction needs . Secondly , I hope in the bottom of the crane boom , with a work space that can accommodate gradual build tall buildings , for high-rise buildings , the hope that the work space with high building construction increased in order to avoid the crane boom collide with the building elements and hinder construction . For this reason, in construction , tower cranes than truck cranes, crawler cranes applied more widely , as construction and installation engineering lifting a variety of building materials, components , equipment , tools, major construction machinery.
Any one tower cranes , regardless of their technical performance and structure , what is the difference , the total can be divided into three parts: the metal part of the working body part and the drive control system parts.
Tower crane metal structure parts are: the tower , the tower head or tower cap , lifting boom , boom equilibrium , slewing ring frame, chassis , trailer chassis and other major components account . For special tower hoist gantry crane , because the differences in structure , components also increase or decrease . A complete tower crane is a combination of these major components assembled together to form a whole. He was subjected to various workloads are functionally similar to the human skeleton.
Tower crane working body in order to achieve a variety of mechanical movement , to achieve the desired mechanical action and set up all the mechanical parts in general. For example, a performance of perfect self- climbing tower crane , often prepare the following working bodies : hoisting mechanism , luffing mechanism , slewing mechanism , traveling mechanism and lifting institutions. Some well as its variety of supportive institutions . Completion of the function of these institutions are: lifting mechanism to achieve goods rise and fall ; luffing mechanism to change the amplitude of the hook position ; slewing jib crane can do 360 reads rotation, changes in the level of work within the hook location, even in the stationary tower case can also hook the center tower crane slewing ring area as the center position in tune ; traveling mechanism so that the entire tower crane operation, change its operational sites ; top l institutions to make part of the tower steel crane slewing movements, thereby changing the working height of the tower crane .
Tower crane driving control system is another important component. Drives to provide power for a variety of organizations , the most commonly used for the YZR and YZ series AC motors. Control system and working mechanism drives the implementation of brake control , complete body starting, braking , speed control and redirect the work of the organization to achieve security monitoring, play a security role , and timely use of the work kinds of parameters displayed, let drivers know , be aware of when operating . Superior performance of a tower crane work , must be in good , safe, reliable, long-lived co-ordinated with the control system .

With the two sessions, the state policy of steady growth will gradually pulling, 2013 optimistic about the situation of the industry as a whole. Of course, the industry should return to the previous level in 2011 is still very difficult, the next 20 years, gantry crane industry will have good prospects, the industry will continue to develop steadily, ups and downs of the phenomenon will be rare.
China steel crane industry has about highlights: First, from a global perspective, tamping the foundation, attack high, strong management. Second, national policy support, major key components imported duty-free, the key hydraulic components collaborative platform construction, business transformation projects progressing smoothly. Third, the rapid progress of the industry to the inventory. Fourth, the momentum of rapid productivity growth was suppressed, corporate expansion momentum slowed, industry rebound signal enhancement. Fifth, the international market is expected to grow.
High-end equipment manufacturing, to big to say, a symbol of a country's core competitiveness, involving the country's economic and national security; talked to the small, many industries and businesses related to the survival and development.
Excavators, cranes and other products in the first quarter sales were down about 20%
Since the second half of 2012, subject to the impact of falling real estate investment growth,
steel crane concrete machinery sales began to decline until 2013 a quarter has not improved. From sales data, excavators, cranes and other products in a quarter, about 20% in sales volume decline. Sluggish downstream demand, accounts receivable bad debt problems of the company tightened conditions of sale, profits are at a greater impact.
However, overhead gantry crane after entering the second quarter will accelerate investment in infrastructure, two quarters of recovery is expected to remain the industry. March 2013 to excavators, loaders,overhead bridge crane represented by sales of construction machinery product range has been narrowed down to about 5%. 2 quarter, with investment in infrastructure and the market is expected to accelerate the improvement of growth in sales of construction machinery is expected to remain.

Lifting machinery industry has gradually become automated enterprise market should not be overlooked
According to statistics, in recent years, lifting and transport equipment manufacturing industry maintained an average annual growth rate of over 30%, even in 2008, after the financial crisis hit in 2009,steel crane has also been a rapid recovery. Meanwhile, the lifting machinery industry's rapid development has greatly facilitated automation products in the industry application. While China's machinery industry automation applications lifting the overall level is not high, but neither the manufacturer of lifting machinery or lifting applications users have come to realize the advantages of automation products. China Academy of Building Research Building Mechanization Research Branch Technology Center Director Luo Wen said in an interview, the lifting machinery industry automation products application potential is very large,hoist gantry crane very broad prospects, rotary kiln so that domestic crane automation market development will follow The "explosive." Both cities to develop more mature and modern form of trends or economic crisis, the state infrastructure investment on the irritant, Chang said the lifting machinery are booming. From control to drive and automation products in this industry are increasingly accumulated depth applications. From the existing scale for future growth and the current growth rate,sino hoist lifting machinery industry has gradually become automated enterprise should not be overlooked in the market.
Crane constrained by the drive difficult to meet the special requirements of developing
Lifting and transport equipment as the national industrial production of special equipment, widely applied to various industries, with the industrial production of the crane speed performance requirements continue to increase, the
steel crane speed control method commonly used traditional wound rotor induction motor due to its collector ring and brush prone to failure, along with a large number of relays and contactors are used, resulting in a large amount of on-site maintenance, speed control system failure rate is high, comprehensive technical indicators are worse, has been unable to meet the special requirements of industrial production.
In recent years, with the continuous development of inverter technology, inverter performance and increasing the mechanical properties of hard-frequency control, speed range, speed and high precision, good stability, easy to control and energy-saving features, can well meet lifting equipment safe and stable, reliable, good operability reliable,hoist gantry crane maintenance requirements, rapid breakthrough in the crane industry and widely used.
Currently, in many inverter brands, can fully meet the needs of lifting products industry characteristics are not many, the main difficulty is due to the particularity of the crane, crane drive must have some special properties: fast dynamic response, in order to meet the crane dramatic changes in load demand; wide range of speed control, the speed can cause the motor output segment around 2 to 3 times the rated torque of the torque output of the peak; can withstand dramatic changes due to the potential energy of the load current impact and guarantees appear in a continuous and reliable operation of mechanical vibration environment; decelerating the motor during braking can be reliably released renewable energy, as the current capacity of the brake unit to be larger; protection system with high reliability, for the lifting mechanism, the need to pay particular attention to mechanical after the brake is released immediately before or brake to prevent the "slip hook" of the control;bridge gantry crane possess powerful monitoring system, through the monitoring of implementation of various parameters of the system failure alarm and failure analysis.

China large tonnage crane market is narrow avoid blindly seek large
In recent years, China's crane industry in the field of technical research made a series of admirable achievement. Indeed, China's
bridge gantry crane industry started later than in developed countries, but as China's economy continues to develop, machinery and equipment manufacturing industry continues to progress, the level of the crane manufacturing industry, now more mature, and in technical fields have multiple independent innovation intellectual property rights. At present, China produced only in the domestic construction cranes play a huge role, but also active in the international construction arena, Chinese manufacturing has become increasingly recognized by the world.
Our large tonnage crane crane industry in R & D and manufacturing in recent years has made a major breakthrough in this field has been at the international forefront, which also represents China's construction machinery industry in technology and on a higher level. In addition to the crane industry R & D production personnel tireless efforts, and this is thanks to our national policy for the development of large-tonnage cranes for their support and encouragement. At present, the domestic large-tonnage overhead bridge crane have been out of the country, received worldwide attention.
However, because of its large tonnage crane tonnages level, work efficiency and load-bearing capacity, suitable only for national water conservancy, power plants and other large-scale construction projects are generally custom made according to project needs. Our 2010 production of five years large tonnage cranes, there are four units for nuclear power plant construction. As we all know, last year, a 9 earthquake in Japan, the Fukushima nuclear crisis erupted, also caused the country for the construction of nuclear power reflection. Fukushima nuclear crisis caused great harm, affecting scope, extend the length of time so that the public feel more fear for nuclear power plant construction. Shrouded in clouds under the nuclear crisis, there have been many countries due to security considerations have slowed or even to give up nuclear power construction plans.
Countries are faced with slowing construction of nuclear power program, in the production of large tonnage crane will also enter a cooling-off period. Although large tonnage crane margins high, but low yields, the market demand is also low, so the proportion of overhead gantry crane market is not great. Our cranes for large tonnage crane companies do not have the blind pursuit of technology in active exploration, they should also take advantage of market demand, so as to enable products to better serve the crane construction services.

Summer season is not the most severe
In 2012 more than half the time, now is the summer season, but also in Heilongjiang crane production operations the traditional peak season. Come summer, Heilongjiang
sino hoist market situation did not improve, the first quarter of this year and next year the situation is more optimism. Heilongjiang crane market is not in the harshest of the summer season. According to the current situation, it can be concluded that the 2013 Chinese New Year period, Heilongjiang crane market will face more severe financial pressure.
There Heilongjiang crane market analysis by authorities said that currently, the construction machinery industry low down payment zero down payment cumulative risks are individually detonated.hoist gantry crane Some sharp implement low down payment zero down payment brands, are braving the winter eat the bitter fruit market.
Currently, the construction machinery market in the summer experience winter, the brand continued market agents bear high pressure, but intense competition in the market does not cool. Zhao star believes that the market in general is bad, should more quality services to root out the market, deep market in order to better service to win a good market. To do when the market is good, the market is not good when you have to visit customers, run the market, to prepare for the market upturn.
Market has its own operating rules. The competition between brands, not because of market experience winter and cooling, but will be more heat reclaim. At present, Heilongjiang construction machinery market structure has not yet appeared a big change, but in the economic boom of the downturn, the construction machinery industry reshuffle in the offing. Especially the lack of capital, technology, marketing, and service capabilities of SMEs, will be difficult to get through the winter.steel crane Wei Hongbing also said that with the construction machinery big market adjoining Heilongjiang Agricultural big market, the first half of households have been withdrawn from the market maker. This is the economic boom of the decline, leading to the inevitable result of deteriorating market conditions. Everything pros and cons, but also to the economic slowdown of economic structural adjustment, survival of the fittest to create a work space. Experienced winter construction machinery market will usher in new opportunities for healthy and sustainable development.

Zero down payment finance "tonic" to "poison"
Prior to 2009, Heilongjiang
steel crane market healthy and orderly development. But entered in 2009, to seize market share, some brand manufacturers spearheaded low down payment zero down payment sales offensive. A low down payment zero down time financial "Lotto" conquering big gains. Into 2010, the market competition is more intense, the face of financial "Lotto" the temptation, most domestic brands are successively follow-up are also part of a joint venture brands. Finance lease, mortgage banking financial leverage limits are super zoom, 10% less popular low down payment zero down payment, accounting to certain brands since 2010, over 60% of market sales. Kind of argument is that sold four cars to buy cranes, excavators opened tractor to raise. Therefore, a serious decline in the proportion of high-quality customers, irrational purchase customers increased significantly. Unhealthy competition, seriously disrupting the market, the manufacturer accounts receivable, inventories increased significantly, hoist gantry cranedealer profits bottomed out, difficult to balance income and expenditure, the crane user did not live dry, non-profit-making, repayment difficult. According to the survey, the first half of 2012, the stock of cranes in Heilongjiang usage below 30%, rents fell by more than 30%.
Heilongjiang, deputy general manager Liu Yuehua this spring that because the purchasing power of potential construction machinery was severely overdrawn, the market is constantly blowing big bubbles, cranes ownership is much higher than the actual market demand. With low down payment zero down payment as a financial "tonic" of construction machinery market has accumulated a huge risk, financial "tonic" has become a financial "poison."bridge gantry crane This is not alarmist, and its toxicity is moving from downstream to upstream industries to pass, and has been the weak link in the chain of funds first attack. Enhance the sense of crisis and prevent market risks, market participants should become a priority.

Sales decline of economic air mass harassment Heilongjiang crane market
It is reported that, due to the world financial crisis and the Chinese economy after the recent downward pressure on the few harassing, China's Heilongjiang Province,
overhead bridge crane market is currently suffering unexpected predicament. According to the survey, the first half of 2012, Heilongjiang Province, crane sales volume decline more than 70% year on year, a considerable part of the brand sales fell more than 90 percent.
According to the market survey, in June 2012 in Qiqihar City, Heilongjiang, such as living on the street every day dry cranes have more than 100 vehicles. And this time last year only 10 or so; every day on the street in Harbin and other live dry crane, the total holdings of more than 30%. Throughout the first half of 2012, due to economic cooling trend, Heilongjiang hoist gantry crane users monthly repayment pressure increase, the pressure on, harder to bear than in 2008.
According to the pundits predicted, the second half of 2012, Heilongjiang Province crane market situation does not improve. Because Heilongjiang affected by the winter cold, the construction season is only half a year or so. Once in the autumn and winter, is the macroeconomic improvement, it can not change Heilongjiang overhead gantry crane market less work to do, did not live dry situation.
Heilongjiang Province, Marketing Manager Wei Hongbing large construction machinery, construction machinery market in Heilongjiang have a deeper insight into the trend. Wei Hongbing that Heilongjiang remoteness, industrial and transportation at the national strategic layout in a relatively minor role; Heilongjiang rich agricultural resources, but in recent years the state has increased efforts to support agriculture in the province. Heilongjiang engaged in the marketing of construction machinery, engineering machinery investment operations, we must grasp the characteristics of Heilongjiang construction machinery market, both eyes staring at the city market, but also aim at the rural market. Appears on the current construction machinery "closed car" phenomenon, Wei Hongbing said repayment tardiness led manufacturers to "close off" the parties are unwilling to see, unavoidable outcome. This situation in Heilongjiang still sporadic state. Whether manufacturers or finance lease, mortgage loan customers so reluctant to take this step, are trying to avoid such a lose-lose situation. Wei Hongbing also analyzed that these sporadic cases, since 2011, mainly in the low down payment and zero down payment car customers, the impact is limited. It is noteworthy that the recent national macro-control efforts stepped up to the market release of "firm growth in a more important position" clear signal. Stable economic growth, only to avoid a larger area funding strand breaks happen.

How can we make way for tower crane safety benefits of frequent accidents sentence analysis and countermeasures
Construction safety accidents, casualty rates have been far higher than other industries, the average level,overhead bridge crane which has caused the government departments, the community and the people's attention, security has been elevated to a new height. "People-oriented, cherish life" concept is integrated into the social construction safety management, reflecting the community's respect for human life, is an important manifestation of social progress.
At present, China's growing scale infrastructure construction, construction workers, more and more, and our construction safety management level has been at a low level,overhead gantry crane which makes the situation even more grim construction safety management state.
In the construction safety accidents, tower crane accident frequency is a commonplace problem, partly because it is related to social stability and the lives of staff and the state property of the event; partly because the occurrence of major accidents, live Ministry of Construction, the State Administration of Work Safety reported each year and the corresponding security checks,sino hoist but still every year after another.
Tower crane solve the problem of frequent accidents, relying on national authorities and enterprises at different levels to develop appropriate rules and regulations, and improve the quality of the tower crane is not enough, you also need deeper thinking solutions.

At the recent State Council promulgated the "State Council on financial support for economic restructuring and transformation and upgrading of guidance", once again clearly will increase the "three rural" areas of credit support. Among them,bridge gantry crane for the first time clearly encourage banking institutions to carry out exploration and medium-sized agricultural machinery mortgage pilot. Credit policy to support the further release of the potential market demand for agricultural machinery, including the New Territories Pump including agricultural producers will benefit.
Construction machinery industry: improving margins
The latest National Bureau of Statistics data show that the special equipment industry profit margins steady rise in income among an improvement. We believe that the profitability of the industry is due to the recovery of investment in fixed assets during transport acceleration.overhead bridge crane Although the equipment industry showed signs of recovery signal, the market for the industry's major manufacturers still have concerns the quality of earnings.
Special equipment industry earnings recovery. The latest National Bureau of Statistics data show that in the first four months of specialized equipment industry (including construction machinery manufacturers and coal machinery manufacturers) of revenues and profits continued to recover. During the period, the industry's revenue grew 10.40 percent, an increase of 10.08% compared with the first three months has accelerated. The first four months of year on year decline in industry profits from a quarter narrowed to -11.40% from January to April of -2.10%, from one-quarter profit rose to 5.58 percent from January to April to 5.97%. We believe that the profitability of the industry's recovery is due to transport of fixed asset investment accelerated. First four months of transportation growth in fixed asset investment up 22.0% from a quarter from January to April rose to 23.7%.
Concerns the quality of earnings.overhead gantry crane Although special equipment industry showed signs of recovery, the market for major manufacturers within the industry cash flow and quality of earnings still have concerns. A quarter of the total trade receivables turnover days were 74.04, 68.11 over the previous year increased. Recent rumors on the market so that investors Zoomlion sales data's credibility into question. Subsequently, Zoomlion A shares and H shares traded in May 27 is suspended.
Will be more emphasis on cash flow management. In the early stage of recovery equipment industry, we believe that the market will pay more attention to the quality of earnings reflect the operating cash flow.steel crane In order to control credit risk and enhance operating cash flow in the short term machinery manufacturers will continue to tighten credit sales.

Domestic enterprises how to use the machinery industry favorable policies
Many industries, especially machinery industry will be on the favorable policies and priorities caused by the use of food for thought, because through good policy will usher in machinery industry moderation and recovery of the situation, of course, is still the key developments enterprise itself reflects the strength of the enterprise.
That by a series of favorable policies,bridge gantry crane the overall situation of the construction machinery industry in December last year showed signs of recovery trend. Expected change of government after the handover, the machinery industry indicators data will produce more dazzling results. Based on the "urbanization" strategy is certainly a large number of infrastructure investments fresh oxygen that can rejuvenate the industry, however, the machinery industry capacity issues already exists, if we do not quickly resolved, let diehard when compared to late.
Set off by the policy of the downstream market is strong impetus to the recovery of the machinery industry. "Urbanization" strategy proposed a nationwide infrastructure to stimulate the construction of a large number of investments, including railways, highways,steel crane bridges and so on. Infrastructure construction cycle is longer, the average period is 2-3 years, so in a long time, the application of engineering machinery market has been a certain guarantee, the industry's overall sales and revenues to maintain a certain level will be high.
Good policy can also be a violent "anesthetic." In the great temptation of the market and policy support, more companies will enter the machinery industry, along with more money and a larger capacity. Machinery industry in 2012 is more like a brief encounter the throes of winter, can be an erased. However, the accumulation of low production capacity and technical upgrades stagnant and not because of a lot of money been fundamentally changed, companies get together but easy to cover up the industry itself pre-existing illnesses, paralysis awareness of industry issues.
Investment Advisor in the Research Director Zhang Yan Lin pointed out that although China has had enough. 'Excesses, no plan, "the pains, the relevant departments involved in the country's economy still play an important part in the industry guiding role of science, digestion of excess production capacity, promote technology upgrades and other important aspects of practical significance has not yet appeared policies. Lack of appropriate norms for guidance, a huge market opportunity for the industry,hoist gantry crane but also more likely to be a crisis.

A foreigner in the eyes of Chinese crane industry: Chinese dragon head forward
2007 Will North first time to visit China Beijing International Construction Machinery Exhibition (BICES), few manufacturers concerned about the market outside China. Will North encounter few Westerners
hoist gantry crane on display at the exhibition are cast suspicion.
The end of October 2011, Kevin Walsh flew to Beijing to visit the latest session of BICES. He saw the information supply and demand sides of the market is quite different.
4 years ago Will North BICES visit, the year 10000 truck crane sales that he was shocked that number greatly exceeded the sales of any one country. By 2010, China produced 35,000 truck crane.
By the end of 2011, although small-tonnage truck crane sales in the domestic market may be a slight decline, but according to Stuart Anderson reported that Chinese auto crane manufacturers this year, is likely to create yet another new record.
2007 Will North BICES visit, the Chinese crawler steel crane is only just beginning. Crane Branch of China Construction Machinery Association, the Secretary-General Yongming data presented show that Chinese manufacturers sold 500 units in 2006 crawler crane, 237 units over the previous year increased by 111%, while sales volume in 2007 is expected around 700 .
2011, according to Stuart Anderson reports, China's users are likely to buy 2000 crawler crane, tonnage in the range of 50 ~ 250t.
Will North visit BICES, manufacturers have focused their attention on the tonnage of the range of products, but only in the domestic market or the emerging markets. Now, many Chinese manufacturers began to manufacture large tonnage crawler cranes, eyes aimed at international users.
Several of China's largest manufacturers spent years developing super crawler crane, its starting weight at least for Germany and the U.S. competitors. Although this process was not always smooth, but China's ambitions all too clear.
This is what it means for the global market? Hard to imagine Chinese overhead gantry crane manufacturer in the near future will dominate many market segments. Those who are not dominant in the market that they will play a more important role on the cost foreign manufacturers are unable to compete with Chinese rivals. The two sides will seek joint ventures and foreign investment in a new plant in order to price around the world increasingly sensitive users with inexpensive cranes.

Lifting cap limiter working principle
Rising limit position limiter gantry crane of important safety device. When hoisting motion, the spreader in working height range. At the maximum working position, the spreader with the top of the supporting mechanism (such as a frame or a small crane,steel crane etc.) should have a certain distance.
The specific size of this pitch, gantry crane drivers difficult to master at work, coupled with inevitable negligence in work. Therefore, if no increase in the limit position limiter installed or malfunctioning limiter, crane work, the spreader may occur to the upper support structure top and rising operation of the drive system can still continue pulling the spreader,overhead gantry crane which causes wire breakage, and the spreader falling accidents.
Gantry crane used limiter caps and maintain its effective work to prevent similar incidents from happening, so "crane safety regulations" in the states: all power-driven crane, its lifting mechanism (including main and auxiliary hoisting mechanism) , should be installed up limit position limiter.
Gantry crane rising limit position limiter basic principle is the separation of a drive by the lifting motion action to trigger an electrical switch, resulting in increased transmission system to stop working, which play a protective role.hoist gantry crane The common form of hammer and screw.

New impetus for economic development, urbanization strategy may be determined on the
Looking ahead, the economic development of the new momentum will likely determine the new urbanization strategy, which will also be long-term development of China's industry there is a greater impact,steel crane it will be the key point of the second half of investment strategies. Nevertheless, the elimination of excess gantry crane industry production capacity is inevitable, the current situation will not hesitate policy. Future investment opportunity lies in industrial restructuring, which has been continued more stock response.
In the first half from the gantry cranes and other machinery and equipment performance of listed companies, this year's first quarter, nearly 10% of listed companies have revenue fell nearly 33 percent beyond the 30% revenue decline of listed companies range from 0% -30% of persons that, although the overall decline in investment in machinery manufacturing sector to bring great restraint, but from different segments within the plate as attributes, performance differentiation will be more obvious, energy saving class machinery manufacturing enterprises may have a better representation in the second half.
Constraints hoist gantry crane and other machinery manufacturing industry, but also in the overall performance of the overall macroeconomic situation of the judgment. Analysts believe that the 2013 annual fixed asset investment growth will be lower than 2012 levels, the cumulative growth rate or 19-20% or so. Judgments based on historical experience, expected in 2013 machinery or industrial fixed assets investment growth of 18% -19%, and continued to decline compared with 2012, while the growth rate of investment in manufacturing or in the proportion fell to 23% -25 % or so.
Specific representation from the previous section, it is expected in the second half of 2013 the radical general machinery, bridge gantry crane and other machinery or difficult to have systematic investment opportunities. Noteworthy that the current growth of the local high presence of machinery and equipment industry segments higher valuation problem, and then choose to wait for a callback intervention price.

Gantry cranes and other machinery industry restructuring direction?
bridge gantry crane and other machinery industry restructuring in the direction that the new urbanization, energy restructuring, industrial automation, environmental protection. This will promote the railway (MTR) oil service and equipment, agricultural machinery, industrial automation, and environmental and related equipment of new coal chemical industry development 6. Consider the future direction of investment and investment strategy should follow certain principles.
Specific "target selection, should consider the following four aspects: First, gantry crane market pioneers, the limited availability of our qualified enterprises; Second, with certain technical storage or access to technology through a variety of channels leading provider of enterprise; Third, adequate own funds, do not blindly rely on financial subsidies to obtain working capital and enterprises can achieve positive returns; Fourth, industrial layout reasonable forward-looking enterprises.
In addition, the concern sub-sub-portal overhead bridge crane and environmental protection equipment industry. Environmental protection equipment in the second half of the more favored areas with solid waste disposal of garbage power generation related equipment, as well as the corresponding demand for desulphurization equipment.
Expected to "Twelve Five" period gantry crane market capacity of about 61.4 billion yuan -921 yuan. Denitration equipment on the field, the next three years, machinery and equipment industry, larger market.overhead gantry crane Due to mechanical equipment sub-sectors and urbanization as well as consumer and other areas closely related to the development of these sub-sectors is projected to exceed the overall industry.

Year is expected to continue to show a moderate recovery trend
Macroeconomic steady growth this year, construction machinery market demand slight signs of growth. However, the second half of the market situation is still not optimistic. From the gantry crane manufacturing sentiment index business research points situation,sino hoist July sales in line with expectations. Most companies reflects off-season market has stabilized, an improvement in the data although there will be some, but the market is expected to be more cautious, manufacturers generally considered the situation in the second half does not have much improved.
Second half of the construction machinery market may be two possibilities: one is the national introduction of small-scale economic stimulus policies, stimulating part of the demand; Another is to maintain the existing national policy is essentially the same, gantry crane market has no other special occurs. Overall, in the country to play a greater emphasis on market allocation of resources to the basic role in the context of the second half of the construction machinery market is expected to be a "stable" state of operation.
In the economic environment is more complex, gantry crane industry operating situation is more grim backdrop,hoist gantry crane foreign trade exports of machinery industry is also very grim situation, the cumulative export growth continued to drop.
Basically reflects current industry running real market situation, subject to supply and demand, and non-human control. Since the construction machinery market has entered a smooth development track, companies should focus on their own adjustments. For example,steel crane to enhance the competitiveness of enterprises, improve service quality and other aspects.

Description of tower cranes
Construction tower crane is the main equipment, currently there are about 320 tower crane production plant,sino hoist tower crane production reached two million units, has greatly improved construction conditions, and improve the efficiency of construction. But what can be annoying is that in the course of the tower crane, plane crash accidents have occurred, these people have to tower crane technology, production and market re-examined.
In recent years, the booming real estate industry, the tower crane market situation is hot, some entrepreneurs have launched optimistic about the market, the formation of the current market competition. In this highly competitive process, some of the emerging tower crane manufacturing plant in order to seize market adoption dumping policy, triggering a tower crane business war price competition war. As the saying goes: "From Nanjing to Beijing to buy than sell fine." Since ancient times, there is no money-losing enterprises to survive it must guarantee a certain profit, if the price is low enough, they will have to make in reducing product quality articles,overhead gantry crane resulting in a decline in quality tower crane products, increasing the risk of the use of tower cranes, tower crane industry, there has been "reign of terror."
Tower crane products as special equipment and general products, involving people's lives and property, and thus security is the first one. We have a clear understanding of the user. In the tower crane purchase and lease process, purchase, lease tower crane performance should have a full understanding, bought good use of tower cranes. To this end I am here today on the tower crane performance,hoist gantry crane structure and process of using the idea of a brief introduction about matters for everyone in the tower crane purchase, use the process to provide a reference.

Tower crane utilization levels, working-level
Tower cranes are intermittent operation of the machine, with a short and repetitive work characteristics. Work agencies stops occasionally, sometimes forward, sometimes reversed. Some
bridge gantry crane working three shifts day and night, some only work group, or even one day only works a few times. Such working conditions showed that: tower crane and its agencies to varying degrees that different busy use different level of tower cranes. While acting on the load on the tower crane is also changing, and some tower crane is often full, and some regular light load, the load situation is very different, that is a different tower crane load condition varies greatly. The use of different levels and loading conditions will determine the different levels of tower cranes work. This tower crane working characteristics of the design of the tower crane parts, metal structures and determine the dynamic power when the
steel crane must be considered. Tower crane working-level staff into both the design basis for the design, procurement, and users should also be a reference for rental of tower cranes. Tower cranes and tower cranes working-level costs are closely related. Purchase and lease of tower cranes, tower cranes to know the purpose of such construction, mounting, use the time and traffic, etc., hoist gantry crane in order to select the appropriate operational needs and affordable tower crane.
Tower Crane Model labeling
At present, China's construction tower
steel crane parameters, the general reference to JG/T5037-1993 "tower crane category" standard for classification, its operating parameters shall not be less than the standard requirements. Performance parameters tower crane tower crane direct impact on production costs, the better the performance the higher the cost, of course, higher sales prices and rental costs. Greater impact on the main parameters are: rated torque, maximum working range, the most significant from the weight, maximum weight, independent and attached working height and working speed.
The model is based on the preparation of the crane rated torque as the main parameters to be defined in order to QTZ80 example as follows:
QTZ80, which represents self-elevating QTZ tower crane, 80 the nominal lifting torque 800kN · m (basic arm and the corresponding nominal weight of product) divided by 10. However,sino hoist due to the impact of imports of tower cranes on the market have a new kind of model identification method, the maximum arm length (m) and the arm end (most significant) that can be lifted at the nominal weight (kN) two main parameters mark tower crane models, such as QTZ80 identified as TC6010, TC5513. Although this labeling method does not meet our national standards, but very directly reflects the tower crane lifting performance, currently used more.hoist gantry crane At the time of purchase and selection of tower crane, you should understand the relationship between the two representations of its lifting torque curve is relatively serious.

The main components of tower cranes
Tower cranes can be divided into three parts: metal structural parts, body parts, control parts. The three most tower
bridge gantry crane production costs in proportion roughly as follows: 60%, 30%, 10%.
3.1 metal structure
Crane crane metal structure is the skeleton. Its role is to bear the weight of the crane and the operation of various external loads by crane, balance arm, tower caps, turret, tower and chassis (walking tower crane also includes frame rails, door frame , outrigger beams, etc.) and other components. Cranes working bodies of the parts are installed or supported on the metallic structure, change the part of the selection and structure is reasonable and is closely related to the safety of tower cranes. The fraction of the cost performance parameters of the crane is not only, but also on the various components of the structure and is closely related to the material of choice.
3.1.1 The main structure
The main tower crane tower crane structure is to determine the cost, one of the main factors, the same argument used tower steel crane over different structural forms, in the same load under the action of the metal structure of the tower crane forces also are exposed different, the size of the natural materials used are different, their production costs will also be very different, but different structural forms have their own strengths, suitable for different project needs, they are widely used in the world, has a strong vitality . Only by understanding their characteristics, the force and the cost situation, in order to properly purchase and use of tower cranes.
Affect the cost of the larger main tower overhead gantry crane structure: tower crane superstructure, tower and chassis systems. However, due to time constraints this only describes the tower crane upper structure.
