Description

A large bridge crane load test device

technical field

The utility model belongs to the technical field of hoisting equipment installation, in particular to a large-scale bridge crane load test device.

Background technique

In the load test of large bridge cranes, steel bars are generally used as the test load (the amount of steel bars in the construction industry is large, and the steel bars can continue to be used after the bridge crane load test is completed, which saves costs and facilitates counterweights). Usually, a temporary hoisting platform is made for the test. When stacking steel bars on the platform, the platform and the hook of the bridge crane are connected by wire ropes. The load test of the bridge machine is many times. Each time the load is increased (or decreased), the wire rope needs to be removed. After the load is added, the wire rope needs to be restored, and then the test is carried out. The conventional load test procedure is cumbersome and the work efficiency is low. With the gradual increase of the load, the steel wire rope is easily scratched with the steel bar, and there is a potential safety hazard.
