In addition to bearing the weight of the object, the lifting hook on the spreader can also withstand the impact of lifting and parking. Therefore, the mechanical strength and impact toughness of the hook should be high, high carbon steel and brittle materials are relatively large, and generally correspond to stress concentration and crack-sensitive, low carbon steel or low carbon alloy steel with better quality.

Lifting hook groups are very wide, generally including: shackles, rings, rings, pear-shaped rings, long rings, combined rings, S hooks, nose hooks, American hooks, chain hooks, unique, novel and safe, suitable for factories, mines, petroleum, chemicals, ship terminals, etc. Guaranteed safety, high quality and safety factor, static load up to 3 times, starting quantity ranging from 5 to 150 tons.

According to the manufacturing method, lifting hooks are usually divided into die forged hooks and hook stacking machines. The hook body is integrally forged, with low cost, easy production and wide application. But once the forging die hook is broken, it can be said that everything is scrapped. The lamination hook of the present invention is composed of multiple rolled steel plates connected and installed in the middle of the buffer. It can buffer the energy pressure. Even if a single fragment occurs, it will not affect the entire breakage and damage.

Lifting hooks are divided into single hooks and double hooks according to their shapes. Single hooks can lift lighter goods, while double hooks can lift heavier goods. The quality requirements for hooks are very high. To achieve safety performance, we must start from the aspects of structural design, material configuration, manufacturing process, etc., and strengthen inspection and maintenance during production and use. If any unreasonableness is found, it should be scrapped in time.
