Leaf Chain

leaf chains are used for fork lift masts, as balancers between head and counterweight in machine tools, or for low-speed pulling (tension linkage). This type of chain is also called "balance chain," and is regulated by ansi. In roller chains, all the link plates have higher fatigue resistance due to the compressive stress of press fits. In leaf chains, only two outer plates are press fit. Therefore, the tensile strength of leaf chains is high, but the maximum allowable tension is low. It is advisable to use safety guards at all times, and be particularly alert to assure the safety factor.
