Leaf chain
Leaf chain is a pin-and-plate lifting chain with no bushes or rollers, built from stacked link plates on hardened pins to carry high static and dynamic tension over plain sheaves. Renold leaf chain is used for fork-lift mast lifting and similar balance and tension duties, where fatigue strength and wear resistance set service life. SES holds the range as an authorised Renold distributor, covering construction Interlaced link plates on hardened pins; plates Special steel for shock and breakage resistance; pins Bending-resistant special steel; standard ISO 4347 / ANSI B29.8. Executions include AL series, BL series, LH series, various lacing ratios. It is specified most often into fork-lift truck masts and straddle carriers. Every part is genuine Renold through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Leaf chain in the parts of a plant where this particular duty actually occurs. In practice that means fork-lift truck masts, straddle carriers, counterbalance and hoist mechanisms, and equally flood defence barriers, machine-tool balances, civil engineering lifting works. What links them is the duty rather than the machine name — type: Pin/plate leaf (no roller). If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the Renold range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Fork-lift mast / lifting duty — BL or LH series to the required load and lacing Runs over a plain sheave, not a sprocket — Leaf chain, not roller chain Corrosive lifting environment — Corrosion-protected leaf chain variant Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Match the truck OEM's lacing and pin type exactly and always renew the anchor/clevis pins — this is a safety-critical lifting item, so sell in matched sets. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
