154HC Mast Section hydraulic lifting system of Tower Crane, published
The lifting and lowering of the tower crane and the jacket frame are used to increase or decrease the standard of the tower crane so that the tower crane can be raised or lowered with the change of the building height, so as to meet the vertical transport needs of buildings with different heights. During the lifting operation of the tower crane, the system needs to carry more than 30 tons of the upper structure of the tower crane.

The working pressure of the system is over 18 MPA, which belongs to the high pressure hydraulic system. The system has the advantages of small volume, light weight, large specific power and stable operation But at the same time, there are some defects such as low transmission efficiency and easy to produce fault. As the hydraulic lifting system of the tower crane belongs to the flow of oil in the pipeline circulation system with sealing and pressure, whether the movement and seal of the parts inside the hydraulic components are damaged or not, it is not easy to notice, so it is difficult to analyze the cause of the failure and to judge the location of the failure. In many tower crane accidents, half of them are caused by improper handling after the system failure In order to avoid major equipment accidents, how to prevent hydraulic jacking system failure, it has become an urgent problem to be solved.
