What Is the LL32 Series Leaf Chain?
The LL32 series leaf chain is a high-performance, plate-link chain manufactured in strict accordance with DIN 8152 and ISO 4347 international standards. Built on a 50.80 mm pitch with a 17.81 mm pin diameter and 6.4 mm plate thickness, it delivers consistent dimensional accuracy and mechanical reliability across the full lacing range — from the 2×2 LL3222 to the 8×8 LL3288. Every link plate is precision-stamped from alloy steel, heat-treated, and shot-peened to eliminate residual surface stress and maximise fatigue resistance over extended operational cycles.
For UK procurement engineers and plant managers sourcing heavy-duty lifting chain, the LL32 series represents a direct-fit replacement or upgrade for existing forklift mast assemblies, telescopic boom hoists, and counterbalanced lift platforms. The four standard lacing configurations give specifiers the flexibility to match exact load ratings and weight-per-metre targets without over-engineering the drive system. Whether you are sourcing for a logistics hub in Birmingham, a distribution centre in Manchester, or a port handling facility at Southampton, Ever Power supplies the LL32 series with full certification documentation and traceable material records — ready to satisfy UK health and safety compliance and LOLER inspection requirements.

Material, Engineering Principle & Operating Scenarios
Alloy Steel Construction
Every link plate in the LL32 leaf chain is stamped from medium-carbon alloy steel with controlled boron addition. After forming, the plates undergo carbonitriding at 820–860 °C, followed by oil quenching and low-temperature tempering. This sequence delivers surface hardness of 58–62 HRC alongside a tough, fatigue-resistant core — exactly the combination demanded by oscillating lift mast applications where millions of flex cycles are the norm rather than the exception. Pins are precision-ground to h6 tolerance and phosphated for break-in lubrication.
Load Distribution Principle
Leaf chains transmit tensile loads exclusively — there is no sprocket engagement, no roller, and no bush. The overlapping plate arrangement means each pin carries load shared across multiple plate eyes simultaneously, dramatically reducing contact stress per unit area compared to a simplex roller chain of equivalent pitch. Increasing the lacing number (from 2×2 to 8×8) multiplies the number of plates in parallel, which is why the LL3288 achieves 1040 kN ultimate tensile strength from the same 50.80 mm pitch geometry as the LL3222 at 260 kN. The design is inherently scalable, deterministic, and straightforward to inspect in service.
Typical UK Application Scenarios
The LL32 series leaf chain is most commonly specified for reach trucks and counterbalanced forklifts operating in UK distribution warehouses and manufacturing plants, where the combination of tight aisle widths and continuous multi-shift duty cycles places severe demands on mast components. It also sees regular deployment in column-mounted hoists in automotive assembly lines across the West Midlands and Yorkshire, in scissor-lift platforms used for aircraft maintenance at UK regional airports, and in quayside container-handling cranes at major British ports including Felixstowe and Tilbury. Anywhere a compact, high-tensile chain suspension is preferred over hydraulic or wire-rope alternatives, the LL32 delivers reliable performance with lower whole-life maintenance costs.
Why Engineers Choose the LL32 Leaf Chain
DIN/ISO Compliance
Fully meets DIN 8152 and ISO 4347, accepted by UK LOLER inspectors and OEM engineers without deviation.
Up to 1040 kN UTS
The LL3288 configuration reaches 1040 kN ultimate tensile strength — covering the most demanding heavy industrial lift systems.
Four Lacing Options
2×2, 4×4, 6×6, and 8×8 configurations let you match the exact load capacity and weight target of any lift system.
Extended Service Life
Carbonitrided plates and shot-peened surfaces extend fatigue life far beyond standard unhardened chain in continuous multi-shift duty.
Full Traceability
Each batch ships with material certificates, heat-treatment records, and tensile test reports — essential for LOLER and CE documentation.
Fast UK Despatch
Stocked configurations available for rapid despatch from UK-based partners, minimising downtime for critical lift equipment repairs.
Manufacturing Capability & Custom Solutions
Ever Power operates a purpose-built leaf chain manufacturing facility equipped with CNC stamping presses, automated heat-treatment lines, and in-house tensile testing rigs calibrated to national standards. The production team holds over 18 years of application engineering experience across forklift OEM supply, port equipment, and bespoke industrial hoist projects — which means when you bring an unusual load case or a non-standard dimensional requirement, you are speaking with engineers who have encountered similar challenges and solved them before.
Our product customisation service covers non-standard pitch multiples, extended pin lengths for wide-clearance mast assemblies, special plate profiles for reduced side clearance, stainless steel plate variants for food-grade or corrosive environments, and pre-assembled chain sections with fitted anchor pins or clevis ends. Minimum order quantities for custom runs are kept deliberately low so that UK maintenance teams sourcing for legacy or discontinued equipment models can obtain exact replacements without unnecessary overstocking. Every custom batch receives the same quality documentation as standard production — no exceptions.

The Challenge
A third-party logistics operator running a 24/7 ambient-temperature distribution centre near Coventry was experiencing premature mast chain failure on its fleet of 18 reach trucks. The existing chains — sourced from a non-specialist reseller — were showing elongation beyond the 3% withdrawal limit within 11 months of installation under a two-shift pattern. Unplanned downtime was running at approximately 14 days per vehicle annually, and the LOLER inspection regime was triggering increasingly frequent out-of-service periods. The fleet manager required a higher-fatigue-life replacement that could be supplied with full material traceability to satisfy their ISO 9001 quality system.
The Solution
After a technical consultation with Ever Power’s application engineering team, the client standardised on the LL3244 (4×4 lacing) for the outer mast position and the LL3266 (6×6) for the inner mast position across the full 18-vehicle fleet. Custom pre-lubricated chain sections with fitted clevis anchor pins were supplied to reduce installation time during scheduled maintenance slots. Full tensile test certificates and heat-treatment records were provided for each batch, enabling immediate filing into the client’s LOLER documentation folder without additional third-party verification.
The Result
After 18 months of three-shift operation, no LL32 series chain across the fleet had reached the elongation withdrawal threshold. Unplanned downtime attributed to mast chain failure dropped to zero. The client calculated an annual maintenance cost saving in excess of £38,000 across the fleet, and the reduced inspection frequency freed up approximately 60 technician-hours per year. The success of the programme led to the client specifying LL32 series chains as the default replacement standard for their other UK distribution sites in Milton Keynes and Leeds.
What Our Customers Say
★★★★★
“We’ve been running LL3266 chains in our automotive press-shop hoists for just over two years now. The difference in service life compared to what we had before is night and day. The quality documentation that ships with every order also makes our internal audit process far smoother.”
James R.
Engineering Manager · Automotive Tier-1 Supplier · Wolverhampton, UK
★★★★★
“We needed a custom stainless variant for a cold-store application at our Aberdeen facility. Ever Power turned around a prototype within three weeks and matched our dimensional drawing exactly. The test reports came with the first production batch — exactly what we needed for our LOLER file.”
Fiona M.
Procurement Lead · Cold Chain Logistics · Aberdeen, Scotland
★★★★★
“Price was competitive versus other UK leaf chain suppliers, but what really won our business was the technical support. The team helped us select between the LL3244 and LL3266 by modelling our actual duty cycle, not just the rated capacity. That kind of application knowledge is genuinely rare in this market.”
