Leaf chains are suitable for any application requiring flexibility, high-strength linkage for reciprocating motion or lifting at relatively low speed. Because of their low cost and long life, these chains are widely used for lift trucks, masts and other lifting as well as construction machines, mining machines and balance or counterweights of machine tools.
Leaf Chains
AL Series (Light Duty)
Consisting of link plates of the same contour and thickness as the pin link plates of ANSI roller chains in the same pitch. Mainly used for relatively constant, low, medium load with less shock.
