Leaf Chain

QY933

Leaf chains are a type of roller chain that consists of interleaved plates that give greater tensile strength than other roller chains. Leaf chains run over sheaves rather than sprockets. They are commonly used in lifting applications such as forklifts and hoists.
1. High tensile strength for heavy lifting.
2. Compact and flexible design.
3. Excellent shock load absorption.

The parts of BL leaf chain is from ANSI roller chain, the plate shape is the same as ANSI roller chain inner plate but higher thickness, and pin diameter is increased. Thus it is a heavy type used for transmission structure of straight back and forth.
