AL 1688 leaf chains for forklifts and material handling

Introduction to AL Series Leaf Chains

AL Series leaf chains, designed in accordance with the ANSI leaf chain specification dimensions, are considered the modern-day version of "lighter" duty leaf chains. They were the first series of ANSI leaf chains ever produced and are still widely used in various lifting applications due to their high-strength, space-saving design.

Key Features and Benefits

What sets our leaf chains apart is the use of high-strength hardened pins, heat-treated plates, and shot-peened components. Moreover, our chains are pre-stressed at the factory to minimize initial stretching upon installation.

Lightweight

As a "lighter" duty chain, the AL series leaf chain is relatively lightweight. This makes it an excellent choice for applications where weight is a crucial factor.

High Strength

The AL series leaf chain is made from high-strength, hardened pins and heat-treated plates. This ensures a high tensile strength, providing excellent durability and longevity.

Corrosion Resistant

The shot-peened components of the AL series leaf chain provide excellent resistance to corrosion. This makes it suitable for use in harsh environments.
