A hook is a kind of picking device for a sling, which includes a hook structure, a hook nut, a hook beam, a bearing, a pulley shaft, a pulley assembly, and a pulley frame. It is widely used in electric hoists and is the main load-bearing component of electric hoists. The hook directly acts on the lifting object and is a necessity between the electric hoist and the weight. The quality of the hook is also related to the safety of the operation, so the production process of the hook needs to be perfect, and the manufacturing materials need to meet the standard requirements.

The strength of the hook assembly will directly affect the work safety of the electric hoist. Before the hook is put into use, the test load value should be checked first. The domestic standards for the inspection of the hook generally use 1.25 times or 1.5 times the rated load as the test load. When the load is removed, the hook opening degree increases. It should not exceed 0.25% of the original opening degree, and the hook can reliably support 1.25 times the rated load without falling off. The international standard ISO and most countries take a load with a residual deformation rate of 0.25%.
