　　Hook is a connecting device in weightlifting machinery. It is a relatively commonly used component, with similar functions such as suspending rings, suction cups, clips, forks, etc. Lifting suction cups, clamps and forks can be used as special lifting devices on cranes for a long time. The auxiliary lifting devices are temporarily suspended on the hook for temporary use and are often used in many types of warehouse work.

　　In the use of lifting devices, if the hook is inflexible or inadequate, the adjustment nut should be checked and checked for damage. If it is damaged, it should be replaced; if the transmission mechanism is stuck, lubricating oil should be added to the active connection of the transmission mechanism. If the guide pin is too tight, adjust the nuts appropriately. If the connection is loose, the transmission tube or other rods are deformed, it should be corrected.

　　For the wire rope on the hanger, lubricating oil or grease should be cleaned in time, especially at the bends of the wire rope. The hook should be inspected at least once every 3 months normally, and it is required to be free of cracks and severe deformation. Pay attention to whether the rope is loose and severely worn. The equipment must not exceed the rated lift weight, and the cushioning spring must not be stretched. During lifting, it should operate stably to avoid deformation due to the influence of tools, cranes or other equipment.
