Everyone knows that crane accessories are essential configurations in cranes, so what are the lifting accessories that are commonly used in crane accessories? The main lifting accessory used is the hook.

Lifting hooks play a great role in lifting heavy objects. In order to ensure safe use, lifting has made many demands on the materials and functions of the lifting hook set. How can it be used to its best effect and the lifting should continue to work hard.

Lifting hooks are a common tool that helps in lifting. Since the hooks on the crane are often subject to great forces during operation, they must be made of materials with good durability. When using the hook group, attention should be paid to the following aspects:

The purchase of lifting hooks must have the manufacturer’s certificate and other technical documents before use; important departments purchase hooks such as railways, ports, etc., and the hooks must be strictly inspected before leaving the factory.

The hook set must not have defects that affect safe performance; the defects of the lifting hook must not be welded and repaired; the surface of the hook should be smooth and must not have cracks, folds, sharp angles, burrs, spalling, overburning and other defects.

You can select two appropriate positions to print non-wearable symbols on the lifting hook opening at a short distance, and measure the distance between the symbols as a basis for detecting whether the opening degree changes during use.

The material of the hook set can be cast from carbon steel or hook-specific materials such as DG20Mn and DG34CrMo. The use of cast hooks is prohibited. The material of the plate hook usually uses A3, C3 general carbon steel, or 16Mn low alloy steel. At the same time, it should be noted that the lifting hook set that has been subjected to overload testing should be discarded.

After reading the introduction, you no longer have any doubts about the hook.
