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 .
