The SY BL646/SY Leaf Chain is a premium 3/4 inch pitch lifting chain engineered for dependable performance in industrial load-handling applications. Featuring a 4x6 lacing configuration, this BL series leaf chain is designed to provide strong tensile capacity and excellent fatigue resistance in forklifts, hoists and hydraulic mast systems.
Manufactured to BL (American standard leaf chain) dimensions, the BL646 chain utilises stacked, heat-treated alloy steel link plates arranged in a 4x6 lacing pattern to maximise load-bearing capability while maintaining a compact operating profile. This robust plate construction ensures reliable operation under repeated lifting cycles and shock loading conditions.
Built from high-strength, heat-treated steel and assembled to strict quality standards, the BL646/SY delivers consistent performance and long service life in demanding materials handling environments. Supplied in a convenient 10 ft length, it allows flexible cutting and installation to suit a wide range of lifting equipment configurations.
