LH10 Series Leaf Chain

Dual-Standard Compliance

Every LH10 chain is manufactured to satisfy both DIN ISO and ANSI chain number designations concurrently. This eliminates costly compatibility headaches when replacing chains sourced from different global OEM equipment, a common challenge faced by UK maintenance engineers working with mixed-origin forklift fleets from Toyota, Jungheinrich, Crown, and Linde.

Precision-Ground Pin Geometry

The pins used in LH10 leaf chains are ground to a maximum diameter tolerance of d2 max = 5.96 mm, maintaining consistent shear resistance across the full lacing range. Precision ground pins distribute dynamic load more evenly through every link plate, which is critical in applications with frequent acceleration and deceleration cycles, such as rapid-cycle warehouse order-picking systems common in UK distribution centres.

Scalable Tensile Strength Range

The LH10 series spans ultimate tensile strength values from 33.4 kN (LH1022/LH1023) up to 133.4 kN (LH1088). This breadth means a single product family can address light-duty pallet stackers alongside heavy counterbalance forklifts rated at 5–8 tonnes. UK procurement teams benefit significantly from consolidating their leaf chain supplier base around a unified series with verified performance data.

Optimised Plate Thickness & Height

With plate height h2 max of 15.09 mm and plate thickness T max of 2.44 mm, the LH10 series achieves a high strength-to-cross-section ratio. The thinner plate profile reduces overall chain weight without sacrificing structural integrity — a genuine advantage in applications where mast height and counterweight balance are tightly engineered, such as narrow-aisle very-narrow-aisle (VNA) trucks.

Corrosion-Resistant Surface Treatment

Standard LH10 leaf chains receive a controlled phosphate and oil (P&O) surface treatment that protects against moisture-induced corrosion — a genuine requirement in British cold storage facilities, outdoor port handling, and coastal industrial sites. Optional zinc-nickel plating is available on custom orders to meet more aggressive environmental conditions, something we discuss in detail with each customer during the application review stage.

Extended Service Life by Design

The relationship between average tensile strength Q0 and ultimate tensile strength Q (min) is carefully balanced in the LH10 series to maximise fatigue life. For instance, the LH1044 achieves an average tensile of 84.5 kN against an ultimate of 66.7 kN, providing a meaningful safety buffer. Longer service intervals reduce total cost of ownership and minimise the operational disruption associated with unplanned maintenance in high-throughput UK logistics operations.

🔍 Core Material & Heat Treatment

LH10 leaf chains are manufactured from high-quality carbon steel and alloy steel plate stock, selected for consistent grain structure and machinability. Plates undergo carburising heat treatment to achieve a hard, wear-resistant outer surface while retaining a tough ductile core — a combination that resists both abrasion and impact fracture simultaneously. Pins are through-hardened from alloy steel bar with controlled case hardness to prevent galling during articulation. Every batch is subjected to tensile proof testing before despatch.

⚙ Working Principle

A leaf chain transmits tensile load through a series of interleaved steel plates joined by hardened pins. Unlike roller chains — which primarily transmit rotary power — a leaf chain is a pure tension member. When load is applied, the force passes through the pin-to-plate bearing interfaces in a predictable, uniform manner across all lacing rows. The lacing configuration (e.g., 4×4 or 6×6) determines how many plate rows share the tensile load, directly controlling the chain’s ultimate and average tensile strength values. This simple, robust working principle is why leaf chains have remained the dominant choice for forklift mast applications for decades.

🏭 Typical Application Scenarios

• Forklift mast elevation systems (counterbalance & reach trucks)
• Pallet stackers and order-pickers in UK distribution warehouses
• Industrial hoists and overhead lifting gantries
• Port container handling and dock leveller mechanisms
• Automotive press loading and transfer systems
• Cold storage vertical conveyor and lift table applications
• Agricultural machinery elevation and tensioning assemblies
• Offshore oil & gas deck handling equipment

⛭ Bespoke Length & Lacing

We manufacture to customer-specified cut lengths, eliminating field trimming waste. Non-standard lacing patterns and mixed-lacing assemblies are engineered based on your load calculation data, making us the preferred partner for UK OEM equipment builders who cannot use off-the-shelf configurations.

🔨 Surface Finish Options

Beyond the standard phosphate-and-oil finish, our factory offers zinc-nickel electroplating, hot-dip galvanising, and specific food-grade lubricant pre-application for clients in the UK food processing and pharmaceutical sectors who operate under strict hygiene standards or require NSF H1 compliance documentation.

📋 OEM Documentation Support

We provide full mill certificates, material test reports (MTR), tensile test certificates, and REACH/RoHS compliance declarations as standard with each shipment. This documentation package is particularly valued by UK engineering procurement teams managing ISO 9001 supply chain audits and LOLER (Lifting Operations and Lifting Equipment Regulations 1998) compliance requirements.

📈 Volume Flexibility

Our manufacturing capacity supports both small-batch prototype orders for R&D teams and high-volume blanket purchase orders for national distributor networks. UK buyers benefit from DDP (Delivered Duty Paid) shipping terms to major ports including Felixstowe, Southampton, and Tilbury, with standard lead times of 15–25 working days from order confirmation depending on specification.

“We had been buying chains from three different suppliers depending on availability. Standardising on Ever Power LH1044 across the fleet simplified our stores management dramatically and the failure rate data speaks for itself.”

— Site Maintenance Manager, 3PL Distribution, Birmingham

“We source LH1066 chains for a series of heavy-duty overhead hoists used in a steel fabrication plant in Sheffield. The tensile strength consistency batch-to-batch is noticeably better than previous suppliers we’ve tried. Documentation package meets our ISO 9001 audit requirements without any back-and-forth.”

“We operate a fleet of reach trucks in a cold-store facility near Rotterdam. The phosphate-and-oil finish on the LH10 chains holds up well in the wet transition zones between ambient loading bays and -22°C freezer chambers. We’ve been reordering from Ever Power for 3 years now and the price-per-metre is very competitive for the quality.”

Cold Chain Logistics · Rotterdam, Netherlands

“As an independent forklift service dealer covering the Greater Manchester area, we need a leaf chain supplier we can actually rely on for quick turnaround. Ever Power consistently delivers within the lead time quoted and their technical support team has twice helped us select the correct lacing specification when a customer’s original OEM chain was discontinued. That kind of application knowledge is rare.”
