Lifting chain is composed by a long list of oblong chain. Comic material is made of Q215, Q235,20MnZ and MnV round by forge welding or soldering simmer. Welded chain according to the ratio of the pitch diameter D T and round, divided into two long-chain and short chain. Said long chain, NA and cranes. Short chain size, lifting chain price for cranes; bending stress because when it is wound around the pulleys or rolls, and tangent chain produced at much less than the long chain. Lifting chain welded, press manufacturing precision different standards, specifications chain and is divided into two kinds of non-standard chain. In use, the lifting chain around pulley smooth surface, allowing the lifting chain there are some errors in the longitudinal direction, each pitch error allowable value. This chain has become a non-standard chain. Because the lifting chain when used in flat pulley, he can slide along the wheel surface, so that mechanical lifting chain, must be fixed to the burden she had to end load. On the contrary, it is required to bypass the surface of the chain pulley special oval recess, which requires a chain fall exactly recess, then pitch error not greater than 0.03d, error no larger than the width. This chain has become standard chain. Lifting chain advantage for any direction have good flexibility, bending stress generated when bending small compared to other rigging. However, since there are major welding chain, easy to wear, lifting chain, is extremely sensitive to shock loads and sudden rupture characteristics. Should be used with strict attention and examination. 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. When we in the selection of lifting chain, lifting chain sprocket, the first to pay attention to the appearance of the check: inside / outside links deformation, cracks, corrosion embroidery; roller whether cracks, damaged by excessive wear and tear; abnormal sounds during operation or abnormal vibration, chain lubrication is good; the joint is loose deformation; pin is deformed or rotated, embroidered eclipse.
