Consisting of link plates with next large size pitch chain of ANSI roller chains. Chiefly used for medium load with greater shock.
Leaf chains are well suited for any applica-tion requiring flexible, high strength link-age for reciprocating motion or lift at rela-tively low speed. For their low cost and long life, widely used for lift trucks, masts and other lifting as construction and min-ing machines and excellent as balance and counterweights of machine tools and so forth.
