Leaf Chains are made for high load, slow speed tension linkages. Often they are specified for reciprocating motion lifting devices. The chains are typically supplied to a specific length and connected to a clevis at each end. Leaf chains are available in AL or BL style. The BL is preferred as they conform to the ASME/ANSI B29.8 american standard.
