[0002] ‌Hook rigging‌ is a component of cargo rigging on ships, with a cargo hook at one end, mainly used to lift cargo. Cargo rigging refers to a set of rigging that hooks or grabs cargo and transmits the pulling force of the cargo winch to lift and lower cargo. It generally includes a hook device, pulley, cargo rope, and connecting parts such as shackles, eye plates, and rings. In the boom device, cargo rigging, jack rigging, and guy rigging are collectively referred to as cargo rigging. Cargo rigging is a component that directly bears the lifting load. The quality of its product is directly related to the safety of the lifting operation. The hook device is an important component of cargo rigging. It is generally composed of parts such as cargo hook, swivel, hook, shackle, weight and triangular eye plate, which are used to hook and lift cargo. The pulley, also known as the windlass, is a simple machine made according to the principle of leverage. It can save effort and change the magnitude and direction of the force. It is an important accessory for many lifting devices. Pulleys can be used individually or as a combination of multiple pulleys. They can be divided into many types according to their manufacturing materials, number of pulleys, structural characteristics, and lifting hook devices.
