Product Description
Leaf Chain serves as a universal, high-tensile lifting and balancing solution designed to operate seamlessly across the entire spectrum of modern material handling and heavy machinery. From the critical mast assemblies of forklifts, reach trucks and telehandlers and the synchronized boom extensions of excavators, concrete pumps and cranes to the precision vertical drives of automated storage systems (AS/RS), stackers, aerial work platforms and industrial lifts, these chains provide unmatched stability and safety.
Our professional manufacturing team produces high-performance Leaf Chains specialized in supporting the safe and efficient operation of material handling and lifting systems. We adopt premium materials including high-carbon steel, 40Cr/50Mn alloy steel, and optional stainless steel, combined with advanced precision punching, professional heat treatment, shot peening technology, and automated assembly processes.
