The correct operation method of bridge crane

The operation of bridge crane includes new machine testing and precautions during operation. The following is a summary of the correct operation method of bridge crane by the editor of Shandong bridge crane manufacturer:

Firstly, for newly installed cranes that have undergone major repairs or changes in important performance, a lifting test should be conducted in accordance with the relevant regulations for crane performance testing before use;

Secondly, before each shift of crane operation, no-load lifting, rotation, amplitude adjustment, front, back, left, right operation, as well as safety performance tests of brakes and limit devices should be carried out. If there is a malfunction in the equipment of the bridge crane, it should be eliminated before it can be officially used;

When lifting heavy objects, the wire rope of the hook should be kept vertical, and it is forbidden for the wire rope of the hook to drag the lifted object in an inclined state. When the hook is attached but the lifted object has not yet been lifted, it is prohibited to move the position or make rotational movements during lifting. It is prohibited to lift or remove items buried underground, solidified underground, or of unknown weight;

When lifting and rotating heavy objects, the speed should be uniform and steady to avoid danger caused by the swinging of the objects in the air.
