For their low cost and long life, widely used for lift trucks, masts and other lifting as construction and mining machines and excellent as balance and counterweights of machine tools and so forth.

Construction and Lacing Combinations

Built of interlaced plates held together by riveted pins. The chain nomenclature indicates the lacing combinations.
