Overview of claw hook
Made of high-quality alloy structural steel by forging. The test load is 2 times the rated working load, and the minimum breaking load is 4 times the rated working load. The forging is subjected to heat treatment. The hook has markings such as rated working load and product grade.
1. Characteristics
The hook is mainly used as a connecting tool in lifting operations. The ultimate working load and applicable range of the use and operation of the hook, as well as the testing and usage basis, have the characteristics of small volume, light weight, and high strength; Overloading is strictly prohibited.
2. Application
Widely used in important industries such as ports, electricity, steel, shipbuilding, petrochemicals, mines, railways, construction, metallurgy and chemical engineering, automobile manufacturing, plastic machinery, industrial control, highways, large cargo transportation, pipeline auxiliary equipment, slope tunnels, shaft treatment and protection, maritime rescue, ocean engineering, airport construction, bridges, aviation, aerospace, venues, and infrastructure engineering, as well as mechanical equipment.
