China Construction Machinery Industry Association Concrete
bridge gantry crane Branch of the past 10 years statistics show that China's holdings of concrete machinery mainly include: 50m3 / h above the mixing station (F) 33931, 44993 concrete pump station, pump 39,889 units, mixer truck 228,822 units; 350L concrete mixer over 200,721 units, reached a total of 548,356 units. The actual construction of the statistics show that a lot of mixing stations produce less than 50% of design capacity.
Although the rate of production is not high, but the industry development prospects of low-threshold access and still continues to attract investors to enter, while the concrete
hoist gantry crane industry upstream customers, their bargaining power is gradually strengthened.
Concrete manufacturing companies, construction units, and leasing concrete machinery industry accounted for about 80% of the purchasing market share. With conch, landscapes, Jidong, Yatai, Huaxin, China Resources Cement and other large enterprises have entered the concrete market, the company's strong organizational performance and cost advantages will bring new competition; On the other hand, local industries and enterprises concentration is increasing, such as Shanghai construction Group, and its subsidiary companies accounted for the total production of concrete concrete in Shanghai 30% of total market share, which will further enhance the bargaining power of buyers, the size of concrete machinery products, quality and service will also put forward higher requirements.
Throughout 2013, we expect concrete
steel crane industry consolidation will further exacerbate the product will also provide lightweight, large-scale, high-end, integrated direction. But this also brings another problem --- new machine sales space will be further squeezed upgrading products. Those that produce small, but the high cost of SME, you need to leading enterprises under the law of diminishing marginal utility, to seek a breakthrough in market segments.

2013 Construction Machinery difficult transition ahead to where?
Chinese economy continues to decline, the construction steel crane market worse. First half of the construction machinery industry in the voices of doubt in the market difficulties ahead. Infrastructure projects, real estate projects 3 years experience pick up weak, sluggish construction machinery enterprises in the development of enterprises in the reflection direction. No sunset industry only sunset business, how to stand out from the weak market. Construction machinery enterprises in transition to where?
Chase "niche market" clinging to the main industry
German SMEs are called "pearls scattered all over Germany," their way of life may bring us some enlightenment. German professor Hermann Simon 1996 publication of "hidden champions: from around 500 outstanding enterprises unknown revelation," a book that will attract world attention to the obscurity of these German companies: their scattered throughout Germany and numerous , small, mostly family-owned businesses, low-key acting in their respective market segments are veritable leader. These "hidden champions" The reason why people have long been neglected, an important reason is that their products there are only a part of the terminal consumer products,hoist gantry crane such as car sunroof parts; others are very easy to overlook small, such as buttons or drink label on the bottle. Frankfurt University of Finance and Economics Management Bowflex experts pointed out that Germany is a significant feature of SMEs in its products often for the "niche market", it is difficult to know by the public. However, once the German companies with strong manufacturing technology in the market segments to establish quality advantage, they will continue to increase investment in research through innovation to consolidate and expand the lead. For the German family-owned enterprises, the presence of family members, the company's management for the company's business objectives with long-term considerations, not because of short-term performance pressure to give up long-term goals. German companies generally have dedication.bridge gantry crane Once you enter a trade, they will single-minded focus on this will not be because other sectors "money scene" better and make a fresh start, or a variety of business. This undoubtedly is their success.
Improve value-added engineering machinery products division
As we all know , domestic engineering
sino hoist products due to low-tech products , low added value and criticized . The value-added products to improve construction machinery , engineering machinery enterprises should start with the following points . First, the construction machinery manufacturing enterprises should enhance the manufacturing process to start, increase scientific and technological research and development and technological upgrading efforts, eliminate obsolete processing equipment and technology , but also should constantly absorbing domestic and foreign advanced manufacturing technology, focusing on the development of the design and manufacture application of advanced technology and digital processing technology, the use of advanced technology to improve detection means from the source of quality engineering machinery , so that Chinese construction machinery design, manufacturing techniques to a new level. At present, China 's construction
steel crane product quality still has much room for improvement , there are a lot of infrastructure work to be done. Only through deep plowing of existing products to improve overall product quality, reliability and technical upgrading efforts. The second is to use existing technology technological development , construction and development to adapt to the modernization of mining engineering machinery , control of cutting-edge technology , the leading technology such as micro- control technology, control technology , voice technology , light-control technology , radar control technology, electromagnetic technology , sensor technology and satellite remote sensing technology used in construction machinery , so that the Chinese construction machinery to get rid of silly , big , rough situation. Chinese manufacturing enterprises should be bold to unmanned remote control and direction of development, from a global perspective of the development of construction machinery construction machinery facie a competitive market , will be a high-tech fight, who occupied the commanding heights Who to become the king of the war . Therefore, construction machinery R & D and high-tech manufacturing enterprises should attach importance to the ownership of the new technologies, new products, patents lies in their own hands. Third, from the efficient, environmentally friendly , energy-saving point of view , focusing on product development efficiency and low consumption , energy conservation will be late to an important indicator of construction machinery , construction
bridge gantry crane industry so participants should establish this concept, construction machinery located in the on the basis of efficiency and low consumption , will be a highlight of the development , will bring substantial benefits considerable growth point , the next leader of construction machinery products is bound to preclude the use of emerging new energy -powered devices. At the same time must also consider the process of construction machinery in operation on the environment and personnel safety hazards , focused on solving the noise, vibration and dust of the key technologies to improve the safety of the equipment , the environmental pollution and hazards reduced construction workers minimum , the product of "people -oriented " is also an important criterion for the user to select products .
Development of construction machinery
First, we now have the world's first mechanical manufacturing country, we began to pride, and we are just the world's GDP, but the real gold is not high enough. Our engineering machinery 70% by weight is made mainly structural parts, 30% is imported. And construction
bridge gantry crane for 70% of the profits flow to foreign countries is gone, we are left with 30%. Engineering machinery of the state reflects our entire national machinery industry technology development. Now our sales of 1.5 trillion, more than the United States, Japan, a few years, we'll import of the whole, but we are not power.
Second, our technical equipment has been a major breakthrough, the good news is our engineering machinery relative to other types of overhead bridge crane nearly a decade of development is particularly fast, it is worthy of our pride. However, this technique is not part of our major technological breakthrough, but also worthy of our consideration, like high-speed rail the same. Our technically how many of their own technology, by our innovative technology, we have over other people's technology, in addition to body weight than other people, other than the weight of more than more than others, this is also worth further reflection, we need to reflect further on foreigners are not to create not the biggest, or they do not want to consider a number of factors make the most of. These are worth further consideration.
Third, progress, structural adjustment, we got enough private enterprise development, effective contribution rate of over 50%. Foreign-funded enterprises with state-owned enterprises has also been a corresponding development.
Fourth, import and export, which is our pride,overhead gantry crane from deficit into a surplus, the surplus is growing, and we have imported or foreign sophisticated equipment, they do not pursue this export volume, they are reluctant to give a very sophisticated us, this is our attitude and the attitude of their differences.

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.

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.

Multiple policies favorable construction machinery industry, the potential demand is released
Recently, the machinery industry secondary market performance last week, the CSI 300 Index fell 3.7 percent,hoist gantry crane the machinery industry index fell 2.1 percent, down slightly less than the overall market decline. Year to date, the overall machinery industry performance index and the market index was essentially flat, where metal products, instrumentation, boiler equipment, machine tools, lifting and transport equipment, and textile and garment machinery outperform.
Downstream from the data, in June, the total coal stocks fell 2.8 percent, natural gas production increased by 8.2%; June highway passenger volume increased by 4.9%, road freight grew by 12.1%, the nation's major port cargo throughput up increase of 10.5%. Import and export, May,steel crane excavators total export volume grew 22.3% year on year single month export volume increased by 3.4%; bulldozers total export volume increased by 8.4%, rollers total exports volume fell by 8.1%, total export volume fell crane 33.3%, forklifts total exports rose 17.7% in the number. June, lathes export volume fell 12.9 percent, milling machine export volume rose 4.2%.
In addition, policy support demand driven agricultural machinery agricultural machinery, the central document for ten consecutive years Focus "three rural" enough to appear government support for agriculture determination. 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.
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.
"The first quarter of 2013 to track hot industry analysis report" that was held in the near future where another two sessions, each province's government work report, published in 2013 GDP and fixed asset investment objective, which is generally two few, mostly set at 20% or more. Among them, Qinghai and other 19 provinces and municipalities in the target set at 20% and above, Xinjiang, Gansu, Guizhou and Heilongjiang four provinces set at 30% or more.
