What Is the LH20 Series Leaf Chain?<\/h2>\n

\"LH20<\/p>\n

The LH20 series leaf chain is a plate-lacing chain engineered specifically for vertical load-bearing applications \u2014 most notably the mast lifting systems of forklifts, reach trucks, and overhead lifting equipment. Unlike roller chains designed for rotary power transmission, leaf chains transfer tensile force along a linear path, making them the industry standard wherever precision vertical movement and high-cycle reliability are demanded. The design follows both DIN ISO and ANSI chain numbering conventions, giving procurement teams in the UK and across Europe the flexibility to source against either specification without compromise.<\/p>\n

With a fixed pitch of 31.75 mm, a plate height (h2) max of 30.18 mm, plate thickness (T) max of 4.90 mm, and pin diameter (d2) max of 11.11 mm, the LH20 family covers lacing configurations from 2\u00d72 through 8\u00d78. Each variant is precision-manufactured to achieve ultimate tensile strengths ranging from 115.6 kN on the compact LH2022 right up to 555.1 kN on the heavy-duty LH1088 \u2014 values that reflect the demanding reality of UK warehouse, logistics, and heavy-industrial environments where downtime is never an option.<\/p>\n<\/div>\n<\/div>\n

\n

Why UK Engineers Specify the LH20 Series<\/h2>\n

Six performance pillars that set this leaf chain apart<\/p>\n

\"LH20<\/p>\n

 <\/p>\n

\n
\n
\u2693<\/div>\n

DIN ISO & ANSI Dual Compliance<\/h3>\n

Every LH20 chain is manufactured to satisfy both DIN ISO (LH prefix) and ANSI (BL prefix) standards simultaneously. This means UK distributors and OEM integrators can order once and satisfy multiple project specifications without re-engineering assemblies or managing separate stock lines.<\/p>\n<\/div>\n

\n
\ud83d\udcc8<\/div>\n

Exceptional Tensile Strength Range<\/h3>\n

From 115.6 kN average tensile on the LH2022 to a substantial 555.1 kN on the LH1088, the series offers a calibrated strength ladder. Design engineers can right-size the chain for the exact load cycle without over-specifying, reducing material cost while maintaining generous safety factors that align with LOLER and PUWER regulations in Britain.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/div>\n

Precision Plate Lacing Architecture<\/h3>\n

The interleaved plate lacing \u2014 available in 2\u00d72, 2\u00d73, 3\u00d74, 4\u00d74, 4\u00d76, 6\u00d76, and 8\u00d78 configurations \u2014 distributes stress evenly across every link. This design prevents stress concentration at any single plate, extending service life dramatically in high-frequency lift\/lower cycles typical of busy UK distribution centre operations.<\/p>\n<\/div>\n

\n
\ud83d\udee1<\/div>\n

High-Grade Alloy Steel Construction<\/h3>\n

Plates are stamped from heat-treated alloy steel with consistent hardness profiles. Pins are precision-ground to tight diameter tolerances, ensuring smooth articulation and minimal wear even under sustained loads. The material selection directly supports the high Q-min and Q0 tensile values published in the specification table, giving maintenance teams confidence in the published data.<\/p>\n<\/div>\n

\n
\u2699<\/div>\n

Forklift-Optimised Weight Profile<\/h3>\n

Weight per metre ranges from just 3.40 kg\/m (LH2022) to 13.8 kg\/m (LH1088). This calibrated weight scaling means forklift mast designers can balance counterweight calculations accurately, while mobile elevated work platforms benefit from reduced dead-load in their boom and scissor assemblies without sacrificing the structural integrity required for operator safety.<\/p>\n<\/div>\n

\n
\ud83d\udd5a<\/div>\n

Rapid UK Supply & Custom Lengths<\/h3>\n

Ever Power holds stock of standard LH20 series variants and can supply cut-to-length chains with appropriate end anchors and connecting links for same-week dispatch to UK addresses. For projects requiring non-standard configurations, our engineering team will review drawings and quote bespoke assemblies, keeping British MRO operations running without extended lead times from overseas sources.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Material, Working Principle & Application Environments<\/h2>\n

\"LH20<\/p>\n

 <\/p>\n

\n
\n

\u2696 Material & Heat Treatment<\/h3>\n

The LH20 series leaf chain plates are stamped from medium-carbon alloy steel (conforming to GB\/T equivalent grades) and undergo controlled carburising and quenching processes to reach a surface hardness that resists wear while maintaining ductile core properties. Pin stock is precision-turned from case-hardened steel bar and ground to tolerance class h6, ensuring consistent fit within the plate apertures across the full production run. The combination of hard surface and tough core is what allows these chains to absorb shock loads typical of forklift free-lift sequences without propagating fatigue cracks through the cross-section.<\/p>\n<\/div>\n

\n

\u2699 Working Principle<\/h3>\n

Unlike roller chains where sprocket engagement is the primary transmission mechanism, the leaf chain operates as a pure tensile link. In a standard counterbalanced forklift mast, the chain anchors at one end to the mast carriage and at the other to a fixed point on the frame. As the hydraulic cylinder extends, the chain’s catenary geometry is managed by a pulley (sheave), with the chain bearing the combined weight of the load, the fork carriage, and any dynamic forces generated during acceleration and braking. This means every single link in the chain continuously carries the full working load \u2014 making precision heat treatment and dimensional consistency across all lacing plates absolutely non-negotiable for safe, long-life operation.<\/p>\n<\/div>\n

\n

\ud83c\udfe2 Application Scenarios<\/h3>\n

The LH20 series is the first choice for counterbalanced forklift trucks, reach trucks, very-narrow-aisle (VNA) order pickers, stacker cranes, scissor lifts, and hydraulic dock levellers across UK warehousing and manufacturing sites. Beyond materials handling, these leaf chains are specified in foundry ladle cranes, automotive press tool changers, and agricultural machinery where a compact, high-strength tensile link is required in a corrosive or high-temperature operating environment. UK facilities covered under the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) regularly rely on this series as it facilitates straightforward planned maintenance inspection and elongation measurement.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Challenge: Repeated Leaf Chain Failures in a High-Cycle Cold Store Environment<\/h3>\n

\"LH20<\/p>\n

A third-party logistics operator running a 24,000 sq ft refrigerated distribution centre near Birmingham was experiencing premature leaf chain failures on their fleet of 14 Linde R20 reach trucks. Operating at temperatures between -25\u00b0C and +5\u00b0C across three shifts, the incumbent chain supplier’s product was showing accelerated elongation and pin corrosion within 900\u20131,100 operating hours, far below the expected 3,000-hour service interval. The site’s engineering team calculated that unplanned downtime and emergency chain replacement was costing the business approximately \u00a318,000 per quarter in parts, labour, and lost throughput.<\/p>\n

After a technical review, the procurement manager contacted Ever Power and specified LH2044 (BL1044) chains for the primary lift mast and LH2034 (BL1034) for the free-lift stage. Ever Power supplied chains with additional pre-lubrication suited to cold-store conditions. The first batch of 28 chain assemblies was delivered to the Birmingham facility within five working days.<\/p>\n

Result:<\/strong> After 12 months in service, no chain on the fleet had been replaced due to elongation or corrosion. The site’s planned maintenance team reported that elongation measurements at the 1,500-hour inspection remained well within the 2% condemn limit specified by BS EN 13157. Estimated annual cost saving: \u00a368,000, factoring in reduced replacement frequency, zero unplanned downtime events, and a 15% reduction in lubrication labour. The operator subsequently standardised the entire fleet on LH20 series chains.<\/p>\n<\/div>\n

<\/p>\n

\n
\n

“We switched to Ever Power’s LH2066 for our heavy stacker cranes in our Coventry parts depot. Lead time was fast, chain quality was immediately obvious from the surface finish alone, and the tensile strength data matched the published figures exactly when we bench-tested a sample. Highly recommended for UK industrial buyers looking for a reliable DIN-compliant supplier.”<\/p>\n

\u2014 Mark T., Maintenance Manager<\/p>\n

Automotive Parts Distribution, Coventry, UK<\/p>\n<\/div>\n

\n

“Our forklift fleet at the Port of Felixstowe includes 40-tonne container handlers with demanding lift cycles. After evaluating three suppliers, Ever Power’s LH1088 was the only chain that met both our ANSI and LOLER documentation requirements out of the box. The custom-length supply with swaged pin ends saved our workshop two days of fabrication per vessel turnaround.”<\/p>\n

Frequently Asked Questions<\/h2>\n

Common questions from UK buyers, maintenance engineers, and OEM procurement teams<\/p>\n

\n
\n
\n

What is the correct LH20 series leaf chain to use for a 2.5-tonne counterbalanced forklift in a UK food-distribution warehouse?<\/h3>\n<\/div>\n
\n

For a 2.5-tonne capacity counterbalanced forklift used in a food distribution environment, the LH2034 (DIN ISO) or BL1034 (ANSI) with a 3\u00d74 lacing configuration is typically the first choice. It provides an average tensile strength of 231.6 kN, which typically offers a safety factor well above the 4:1 minimum required by LOLER when applied to standard duplex mast geometry at that rated capacity. For reach trucks and three-stage masts where the free-lift chain is shorter and cycles more frequently, LH2044 provides additional margin. We recommend sharing your mast assembly drawing with our UK technical team for a final confirmation, as mast geometry and sheave radius affect the design working load per strand.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

How much does an LH2044 leaf chain assembly cost from a UK-based supplier, and what lead time can I expect for delivery to England?<\/h3>\n<\/div>\n
\n

Pricing depends on cut length, quantity, and whether you require standard or custom end terminations. For standard cut-to-length LH2044 chains without anchor hardware, indicative pricing starts from a competitive per-metre rate that is typically 15\u201320% below European distributor pricing when ordered directly from Ever Power. For UK mainland delivery, standard in-stock orders dispatch within 2\u20133 working days; custom-fabricated assemblies with swaged or threaded end anchors are typically ready within 5\u20137 working days. Contact sales@leaf-chain.com<\/a> with your specification and required quantity for a firm price and confirmed lead time.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

Where can I find a reliable leaf chain supplier in the UK that can provide both DIN ISO and ANSI chain certifications for LOLER compliance?<\/h3>\n<\/div>\n
\n

Ever Power supplies LH20 series chains dual-certified to DIN ISO 4347 and ANSI B29.8 from a single manufacturing source, which significantly simplifies LOLER documentation for UK site engineers. Each production batch is accompanied by a material certificate (mill certificate), a dimensional inspection report, and a tensile proof-load test certificate. These documents can be issued in English and are formatted to satisfy the written scheme of examination requirements under LOLER 1998. Contact us directly at sales@leaf-chain.com<\/a> to receive a sample certificate pack before placing your first order.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

When should I replace a forklift leaf chain in a UK manufacturing plant, and how do I measure elongation correctly?<\/h3>\n<\/div>\n
\n

Industry practice endorsed by BS EN 13157 and the FLTA (Fork Lift Truck Association) recommends condemning a leaf chain that has elongated more than 2% beyond its nominal pitch length when measured over a 300 mm gauge length. In practice, chains in UK manufacturing environments running two or three shifts should be checked every 500 operating hours, or every six months at minimum. Signs requiring immediate replacement include visible cracking on plate edges, corrosion pitting penetrating more than 10% of the plate cross-section, or any permanent lateral deformation. Our engineering team can advise on setting up a LOLER-compliant inspection checklist tailored to your specific forklift fleet model.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

Which leaf chain lacing configuration offers the best strength-to-weight ratio for reach truck mast applications in high-bay UK logistics centres?<\/h3>\n<\/div>\n
\n

For high-bay reach trucks operating at lift heights of 10\u201314 metres in UK automated storage and retrieval environments, the LH2046 (4\u00d76 lacing) tends to offer an excellent balance. It delivers 291.4 kN average tensile strength while maintaining a weight of just 8.60 kg\/m, which keeps the overall mast assembly weight \u2014 including the chain and its anchors \u2014 within the counterweight balance parameters of most modern reach truck platforms. The narrower pin length (55.09 mm max) also fits within the tighter mast channel widths common to European-designed trucks. For twin-chain mast configurations, our engineers can confirm per-strand load calculations against the mast maker’s data sheet.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n
