1. The chain sling is a practical lifting tool that consists of a lifting ring and other accessories. It can be used as a singleleg choker chain sling when the hook is in the link, but the working load is reduced by 20%. The ratio between service load and breaking load is 1:4. The fourlegged lifting chain sling is made of metal links, according to the shape, they are divided into two types: welding and assembly. 2. The material is quality alloy steel. The outstanding characteristics are wear resistance, temperature resistance, low ductility, no stretching under load, long service life, easy bending, and suitability for largescale applications with frequent use. With its flexible nature and multiple connection points, various combinations can improve work efficiency and reduce costs. Applications include mining, machinery, ports, construction, etc. 3. The breaking strength of the strength chain at T8 grade exceeds 800 MPa. It features a 4:1 safety factor and a test load of 2.5 times, making it easily adjustable for various applications. These products are fully tested, marked, and accompanied by the appropriate documentation. Suitable for use at temperatures above 100°C or below 40°C. For multileg slings, the angle between the strands should not exceed 30° or the specified maximum value. 4. According to safe operation regulations, in addition to routine testing at scheduled intervals, a competent person must conduct inspections. The inspection frequency can be adjusted based on the specific use of the rigging. The following conditions may lead to increased wear, such as frequent use, heightened abrasion, exposure to temperatures, corrosion, or damage caused by other factors.
