Crane Parts: Understanding Their Importance and the Significance of Crane Hooks
In the realm of lifting equipment, crane parts are indispensable components that ensure the safe and efficient operation of cranes. Various lifting parts, such as wheels, hooks, wire ropes, and rope guides, contribute to the overall functionality. Among these parts, the crane hook holds particular significance as a commonly used accessory in lifting operations. Primarily employed for securely attaching goods or materials, it is subject to stringent quality requirements to ensure optimal performance and safety.
To what extent does the lifting hook need to be replaced with a new one?
The crane hook should be replaced immediately when one of the following situations occurs:
1. When the hook is cracked, it must be scrapped.
2. When the wear degree of the dangerous section of the hook reaches 10% of the original size, it should be scrapped immediately.
3. When the opening degree of the hook is increased by 15% compared with the original size, it should be scrapped immediately.
4. When the torsion deformation of the hook exceeds 10¡ã, it should be scrapped immediately.
5. When the dangerous section of the hook or the neck of the hook is plastically deformed, it should be scrapped immediately.
6. When the wear of the hook bushing of the hook plate reaches 5% of the original size, the bushing should be scrapped.
7. When the mandrel of the hook plate is worn out to 5% of the original size, the mandrel should be scrapped.
