AL 822 leaf chains for forklifts and material handling

The AL Series leaf chains were the pioneers of ANSI leaf chains and are still widely used in various lifting applications, owing to their compact, high-strength lifting design. Our offering of leaf chains stands out due to the use of high-strength hardened pins, heat-treated plates, and shot-peened components. The chain is also pre-stressed at the factory to minimize initial stretching during installation.

Product Details

Typically, leaf chains are stocked in 10ft boxes, 50ft reels, and 100ft reels, but we also supply cut-to-length and custom leaf chains. Below are our standard leaf chain sizes in each series (AL3 - AL29).
