A hook is a common lifting device. It can use various types of picking devices according to the nature, shape and lifting weight of the items. Common picking devices include lifting rings, lifting pliers, hooks, permanent magnet suction cups and other lifting rigging.
The hook is mainly used in cranes and other lifting devices to hang items, and can be used together with other pickup devices to complete certain lifting operations. According to its type, hooks can be divided into single hooks, double hooks and rings. According to the length of the hook body, long hooks and short hooks can be divided into long hooks. According to the processing method, it can be divided into forged hooks and plate hooks.
The tail of the hook is often made in a ring or cylindrical shape, and the ring-shaped tail is hung through the ring hole with ropes, chains, and pins. The cylindrical tail is cut with threads—triangular, rectangular, trapezoidal, and zigzag. Triangular threads are only used for situations where the lifting weight is very small. When the lifting weight is more than 5 tons, trapezoidal or zigzag threads are usually used.
There are different ways to connect the hook and the rope. When the lifting weight is less than 3 tons, it can be hung directly or through the hanger on the free end of the rope. When the lifting weight is more than 3 tons, the lower part of the nut can be equipped with a rolling bearing, which makes the hook easier to rotate about the vertical axis.
