CRC leaf chain manufacturing is focused on imperial pitch leaf chains that include BL (LH) series chains (International Standards ISO4347, DIN8152, ANSI B29.8 & NFE26107); AL series chains (ANSI B29.8); and EL (LL) series chains (ISO4347, DIN8152 & NFE26107).
Leaf Chain is the most simple of steel chains, consisting only of link plates and pins. This chain generally has greater tensile strength than roller chains and runs over sheaves rather than sprockets. They are suitable for hanging, balancing or motion transmitting applications. Leaf chains are often used as counterweight chains for machine tools, elevator and oven doors, fork lift truck masts, spinning frames and similar lifting or balancing applications.
