A lifting hook, also known as a lifting pulley, is a device consisting of a hook pulley connected to a wire rope and a crane, bypassing several pulleys at a time.

The basic structure of the lifting hook is mainly composed of straight handle double hooks, insurance clamps, hook beams, thrust spherical roller bearings, hook nuts, pulleys, pulley shafts, deep groove ball bearings, pulley covers, shaft end baffles, pull plates, oil cups and other components. The sling is hung in a double hook with a straight handle. The sling is connected to the object to be hoisted. The wire rope is output to the crane and connected to the pulley block. By controlling the lifting and translation functions of the crane, the purpose of hoisting can be achieved. The double hook form can ensure overall stability.

The lifting hook can achieve passive rotation through the thrust spherical roller bearing on the hook beam. But it must be based on external forces. The hoisted object will only rotate when the worker applies lateral rotational force to the hoisted object. For some products that are large and heavy, workers must exert a lot of force to rotate, and sometimes multiple workers are even required to rotate together. Due to the effect of inertia, the expected rotation effect is often not achieved, the work efficiency is low, and the labor intensity of the helping staff is increased. The shaking and inertia during rotation cannot guarantee the personal safety of workers.
