Secrets on the Crane Hook

Whether it is a gantry crane, bridge crane or jib crane, in order to maximize the use of the crane, most customers will be equipped with a hook. If it needs to be used in other working environments in a short period of time, it can also be equipped according to demand. Electromagnetic chuck or grab and other spreaders.

As the most common accessory in cranes, the hook is easily overlooked by many customers. However, in China, whether it is a overhead crane of 1-25 tons or a gantry crane of hundreds of tons, according to our country's standards for special equipment, the hook must be equipped with an anti-decoupling device.

The hook anti-decoupling device is the hook insurance, which prevents the lifting items from being decoupled due to excessive angle or improper hook during lifting. It can limit the slipping of the rope to prevent the objects from falling off the hook during the transmission process, causing accidents.

Under normal circumstances, after the heavy object is hung, the anti-decoupling device will automatically return to its position under the elastic force of the spring to block the entrance and exit of the hook and prevent the wire rope from falling off from the hook.

If the anti-decoupling hook device is damaged, it may cause the wire rope to be stuck in the hook, which will affect the production operation; and the more serious situation is that the decoupling accident will occur due to the loss of protection.

2. The structural shape and buckle of the hook should meet the design requirements.

3. There should be no loosening or dislocation of the bolts, no cracks in the welds, and no abnormal deformation of the safety buckle.

During inspection, functional inspection is the basic method, and visual inspection and operation test are carried out.
