What are the key points in the manufacturing process of semi-enclosed hook assemblies?
Hook set is composed of pulleys made of large diameter ductile iron and hooks. Next, let’s take a look at the common classifications in lift hooks—semi-enclosed hook groupIt is introduced:
Semi-enclosed hook group is a widely used component product and a common crane accessories. It uses anti-wear roller bearings; the hook can rotate 360 degrees; it is equipped with a spring-pressed safety buckle to prevent slipping. The hook forgings are tempered steel 34CrMoV, T-grade, according to the standard DIN17200. This type of product needs to have certain basic technical requirements. The following are the key points:
1. The semi-closed hook group must not have any defects that affect its performance;
2. No welding or repair;
2. No welding or repair;
3. The surface should be smooth and there should be no defects such as cracks, wrinkles, sharp corners, burrs, peeling, and overheating.
4. You can select two suitable positions to print the mark at a short distance of the hook opening, and the distance of the mark can be measured as the basis for detecting the change in the opening degree.
5. The semi-enclosed hook group material can be made of many good quality carbon steel or special materials. The product must be highly integrated. If cracks appear, it needs to be replaced immediately. If there are cracks, it will be scrapped directly and will no longer be used. If the product has been used for more than the service life or has been used for more than the burden of use, it must be disposed of as waste and cannot be put into use again to ensure the stability of its equipment.
When purchasing a semi-closed hook group, you should choose products with technical documents, such as the manufacturer's qualification certificate; inspection of important departments, etc.
