Lifting hook, English name lifting hook, hook is a common spreader in lifting machinery. The hook is often suspended on the wire rope of the hoisting mechanism by means of pulley blocks and other components.

According to the shape, the hook is divided into single hook and double hook; according to the manufacturing method, it is divided into forged hook and laminated hook.

The single hook is simple to manufacture and easy to use, but the force is not good, and it is mostly used in the workplace where the lifting capacity is less than 80 tons; the double hook with symmetrical force is often used when the lifting capacity is large. Laminated hooks are riveted from several cut and formed steel plates. When individual plates have cracks, the entire hook will not be damaged. The safety is good, but the self-weight is large. Most of them are used for large lifting capacity or lifting molten steel buckets on the crane. The hook is often impacted during the operation and must be made of high-quality carbon steel with good toughness.

The classification of hooks is very wide, generally including: shackles, rings, rings, pear-shaped rings, long rings, combination rings, S hooks, nose hooks, American hooks, claw hooks, eye-shaped sliding hooks, and safety card rings Screws and chain shackles have the characteristics of unique, novel, high quality and safety, and are suitable for factories, mines, petroleum, chemical and ship terminals. Quality safety factor, static load up to 3 times. The lifting capacity is from 5 tons to 150 tons.
