Typing must be clear. The jack can not have a clear position by the top marks. 5. The welding position welding mouth, this position should be uniform welding Baoding lifting chain pictures, deburring to clean, weld location can not be offset occurs to the ring in the middle of the chain, not on the side or lower side. 6. The chain does not appear high and low angle and high side, low side. Chain vertical, generally speaking, the degree of distortion in the vertical chain of a chain of no more than 30 degrees. Lifting chain is based on lifting lifting objects of different heights can adjust the length of the chain is essential for the crane, extract important means to improve the operational efficiency of the crane lifting chain Baoding picture, expand the operating range of the crane plays an important role . It is mainly used for the hoist and other lifting equipment above, it is to enhance one of the important jobs traction hoist rigging. Now widely used in manufacturing, mining, transportation and other fields. Lifting chain known as the lifting chain, lifting short-chain, which is made round butt into short - chain, and after full heat treatment and testing manufactured lifting sling. Lifting chain with high strength, abrasion resistance, light weight, etc., the manufacturing process and strict security quality, in line with the manufacturing standards to ensure that the impact of the lifting chain, capacity, resilience and elongation, greatly improving the lifting chain safety and service life.
