Lynx BL Series Leaf Chain

Leaf chain (also called forklift chain or hoist chain) is a heavy-duty articulated chain built without rollers, using only interlocking side plates and pins. The flat profile and high tensile strength make it the standard choice for lift, hoist, and counterweight applications. Lynx BL series leaf chain follows ANSI B29.8, sized from BL422 through BL2088, in lacing patterns from 2x2 through 8x8 (inner-plate × outer-plate count).

Frequently Asked Questions

What does the lacing pattern (e.g., 4x6) mean?

The lacing pattern describes the side plate arrangement: the first number is the inner-plate count between pins, the second is the outer-plate count. A "4x6" lacing has 4 inner plates and 6 outer plates per pitch. Higher numbers mean more material and higher tensile strength. The most common patterns are 2x2 (light), 4x4 (medium), 6x6 (heavy), and 8x8 (extreme).

Why doesn't leaf chain have rollers?

Leaf chain is designed for tension-only applications (lifting, pulling) rather than driving sprockets. Without rollers, it has a slimmer profile that fits tightly in mast channels and around sheaves. The side plates and pins carry all the load directly. Don't use leaf chain to drive sprockets, it's not designed for that load pattern.

How do I select the right leaf chain size?

Calculate maximum static load on the chain, multiply by your safety factor (typically 4:1 or 5:1 for lift applications), and select a chain whose minimum ultimate tensile strength exceeds that value. Most lift applications follow OSHA and ASME B30 guidelines for safety factors. Consult the chain manufacturer's technical bulletin for cycle-life curves at specific load levels.

Does leaf chain need pre-stretching?

Yes, leaf chain elongates during initial service. Manufacturers typically pre-stretch chain at the factory to 35-40% of ultimate tensile strength, which removes most of the initial elongation. If you buy un-stretched chain, expect 1-3% length increase during first use, which can affect lift travel and counterweight position. Specify pre-stretched chain for precision applications.
