　　The hooks are available in single hooks, C-shaped hooks, double hooks and stacked hooks. Single hooks are mostly used in cranes with medium and small lifting weights. The hook material can be fully utilized and the hook is easy to operate when the double hook is under good stress conditions. Used for cranes with large lifting weight. The C-shaped hook is used for loading and unloading of ships, and the upper protruding part can prevent the hang of the warehouse during lifting.

　　The cross-sectional shapes of the hook body include round, rectangular, trapezoidal, T-shaped, etc. Among them, the T-shaped cross-section is most reasonable, but the process is complicated. The circular cross-section is used for small hooks. Generally, the hooks are trapezoidal cross-sections with arc angles and rectangular cross-sections with arcs.

　　Hooks are often made of die forging, and the head of the hook has threads made of straight handles. The hook head hanging on a single wire rope is equipped with ring eyes. A sheet hook with a large lifting capacity or lifting high-temperature materials is used for metallurgical cranes that are riveted by multiple steel plates and a pad is installed on the hanging port. It will not break suddenly as a whole. The T-frame is safe and has good reliability. Some sheets can be replaced. The sheet hook can only be made into a rectangular cross-section, the hook body material cannot be fully utilized, and the weight is relatively large.

　　To prevent the tie rope from automatically decoupling, a safety locking device can be installed on the hook.
