How to choose a lifting chain? When selecting a lifting chain, it is necessary to consider the load capacity. For hoisting chains made of looped chains, one must look at how many legs the rigging has. For electric chain hoists, one needs to determine which type of hoist and how many rows of chains are used based on its tonnage rating, and measure the diameter of the chains. For hoists that require replacement of chains, it is important to select the same specifications as before. Electric hoist chains and hand-operated hoist chains generally undergo blackening treatment, with a small number being galvanized, and some remaining in their original color with polished finishes. Lifting chains are used in various environments.
