Leaf Chain

Leaf chain also called as forklift chain, includes AL, BL/LH, LL series. Our range of leaf chain for materials handling applications is used worldwide for straddle carriers, forklift trucks and on major civil engineering works such as flood defence barriers.
Link Plates
Plates are made from a special steel which can withstand sudden loads and provides maximum resistance to breakage.

Pins are manufactured from a special steel which has excellent resistance to bending. This increases the wear life of the chain.

Inner Link Plates
Movement of the inner plates is improved by close control of the pin and plate hole dimensions. This reduces rubbing (friction) to a minimum so the chain operates more economically and efficiently.

Chain pitch
Pitch (distance between each pin or plate hole) accuracy and pin hole diameters (holes in link plates) are maintained on every component during manufacture. This ensures consistent precision performance and good movement of the leaf chain joints.

What is a Leaf Chain?

Leaf chain is a rollerless chain that is commonly used on forklift trucks and in other material handling applications. Leaf chain is constructed of steel link plates mounted side-by-side on pins. The contour of the link is the same figure-eight shape found on standard roller chains. The chain can flex at each pin. Leaf chain is used in tension linkage applications, where the chain is kept in tension and can be moved in either direction. Leaf chain is commonly used on forklift trucks and in other material handling applications. Leaf chain is also referred to as cable chain and balance chain.

Applications of Leaf Chain

There are different classes and applications for leaf chain. These include agricultural chain, conveyor chain, engineering steel chain, oil field chain, and power transmission chain.

  • Agricultural leaf chain is used for agricultural applications.

  • Conveyor leaf chain is specially designed for use in conveyor applications. This category includes roller chains with special attachments, flat-top leaf chains, and silent chains.

  • Engineering steel leaf chains are manufactured from machined and fabricated steel. This type of leaf chain can be used for a variety of industrial applications.

  • Oil field leaf chains are heavy-duty chains that are tested according to American Petroleum Institute (API) guidelines.

  • Power transmission leaf chains are used in power transmission drive applications.

Specifications of Leaf Chain

Specifications for leaf chains include series type. There are three main types of leaf chain series: AL series, BL series, and LL series.

  • AL series leaf chains have link plates that are the same contour and thickness as the ANSI roller chain pin links of the same pitch.

  • BL series leaf chains are designed to link plates that are thicker and have a larger contour than the AL series link plates of the same pitch. The BL series link plates and pins are the same as those of the ANSI roller chain of the next larger pitch.

  • LL series leaf chain is based on British Standard chain dimensions. LL series leaf chain conforms to the ISO 606 international standard.
