Analysis and removal of faults in hoisting system of the hydraulic crane of shipping;

To thoroughly understand the dynamic characteristics of oil drilling rig hoisting system,and shorten development time of hoisting devices and save experimentation cost,a simulation model to analyze dynamic characteristics of oil drilling rig hoisting system was established,using automated analysis software ADAMS.

This system was named as new type of workover operation mechanical system, the system main consist of integrated hydraulic tong system and new type of workover operation hoisting system.

Lifting system is a key part of Petroleum drilling rig, a large and complex electro-mechanical system, which is responsible for lifting and putting down the drill stem, feeding the bit in drilling, controlling the bit pressure, as well as dealing with the complicated accidents etc.

Based on the dynamics theory of mechanics,a dynamics mode of rig lifting system was established,which can get the solution of the said problems of fast line pulling force.
