The indispensable role of hooks in slings
As a retrieval device for slings, the hook is widely used on electric hoists and is the main load-bearing component of the electric hoist. Including parts such as hook structure, hook nut, hook beam, bearing, pulley shaft, pulley assembly and pulley frame.
The strength of the hook assembly will directly affect the working safety of the electric hoist. Before the hook is put into use, the test load value should be inspected. Domestic standards for hook inspection generally use 1.25 times or 1.5 times the rated load as the test load. After the load is removed, the increase in the hook opening should not exceed 0.25% of the original opening, and the hook can reliably support 1.25 times the rated load without falling off. The international standard ISO and most countries adopt a load with an opening residual deformation rate of 0.25%.
The hook acts directly on the lifting object and is a necessity between the electric hoist and the heavy object. 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 standard requirements.
