Why does the hook slip when the bridge crane is working?

Bridge cranes use hooks as spreaders and are widely used. Pay attention to crane maintenance during use. A user contacted and said that the hook of the bridge crane used had a sliding problem. Taking this opportunity, the editor will tell you about several reasons why the overhead crane falls when the heavy objects are being lifted:

1. The crane is overloaded.

The lifting capacity of hook bridge cranes of different tonnages is different. If a crane with a tonnage of 20 tons is used to lift 25 tons of things, it must not meet the requirements, which can easily lead to safety accidents. In order to avoid overloading, an overload limiter can be installed on the crane.

2. The brake is not adjusted properly.

If the crane brake is not adjusted properly, the brake may not work properly. When the heavy object is lifted to a certain height and no longer rises, the heavy object may fall. At this time, the brake must be adjusted again. This is generally a double-beam bridge crane , because most double-beam bridge cranes use a hoist as a lifting power source and use a hydraulic brake. The single-girder bridge crane is generally the braking device that comes with the electric hoist.

3. The brake pads are severely worn.

If the brake pads are severely worn, the brakes will also fail and the brakes will not be effective. Replace the brake pads at this time.

When there is a problem with the crane, it is necessary to analyze the problem first and formulate a reasonable solution. Sometimes a little mistake may cause serious consequences. Therefore, when operating, strictly abide by the crane operating regulations.
