Chain rigging is made of metal chain link connection rigging, there are two main welding and assembly in accordance with its form, its structure alone and more than two, etc., using high-quality steel, it features a wear-resistant, high temperature ductility low, after the force will not stretch like. This high-strength chain rigging can be divided into those levels: the chain is divided into 120 chain rigging, chain rigging 100 and 80 rigging. 100 chain rigging made of special materials manufactured under the same intensity 25% higher than the diameter 80, and 120 chain strength higher than 100 by 25%. China's lifting equipment plant mainly produces or 80 lifting chain rigging, lifting chain, like 100 and 120 rigging lifting chain rigging manufacturers is still very small, hoisting lifting chain, this high since heavy chain rigging mainly some big foreign manufacturers to be able to produce this high-strength special steel lifting chain. 1,100 level is super-type chain rigging chain rigging, compared with 80 chain, super-type biggest advantage is in the same diameter, the rated load of up to 25%, that is at the same rated load , lifting chain GB, 100 chain with a diameter smaller. 2,100 grade chain rigging surface has a higher hardness and better toughness. Chain links and attachments more wear. 3,100 grade chain rigging temperatures up to 200 degrees = 100% of the rated load of 200 degrees to 300 degrees = 90%, 300 degrees to 400 degrees = 75% 4,100 grade chain rigging elongation at break of a minimum of 20% may be . 5,100 grade chain rigging system can not be mistaken, because only chains and accessories have the same level in order to connect to each other. Lifting chain hoist is required for parts, but how to select the right lifting chain? The problem may be a topic of concern many of my friends. Then chen to provide you with information, I hope for your help. Lifting chain chain can be adjusted according to the height of lift lifting objects of different lengths crane essential extract important means to improve the operational efficiency of the crane to expand the operating range of the crane plays an important role. We in the selection of lifting chain, the black lifting chain, first of all pay attention to check the appearance of: inside / outside links deformation, cracks, corrosion embroidery; roller is crack, Jinhua lifting chains, damaged by excessive wear and tear; running. abnormal sounds or vibrations when abnormal, chain lubrication is good; the joint is loose deformation; pin is deformed or rotated, embroidered eclipse.
