What Is the LH40 Series Leaf Chain?<\/h2>\n
\n

\"LH40The LH40 Series leaf chain is a precision-engineered, high-strength plate chain manufactured in full compliance with DIN ISO 4347 and corresponding ANSI BL standards. With a pitch of 63.5 mm and chain lacing configurations ranging from 2\u00d72 to 8\u00d78, it delivers a working tensile range from 433.7 kN up to 1,734.8 kN ultimate strength \u2014 making it one of the most versatile heavy load chains available to UK buyers. The LH40 series is the backbone of mast-type lifting assemblies in counterbalance forklifts, reach trucks, and high-rack stacker systems across Britain’s warehousing, ports, construction, and manufacturing sectors.<\/p>\n

Each link in the chain is formed from heat-treated alloy steel plate and a hardened, precision-ground pin. This combination resists cyclic fatigue, lateral shock loading, and the kind of low-speed, high-torque stress cycles that would destroy lesser chains within months. The result is a leaf chain that regularly achieves 20,000+ operating hours in documented field applications \u2014 a figure that resonates strongly with UK fleet operators facing tight MHE maintenance budgets.<\/p>\n

Ever Power has supplied the LH40 series to clients across England, Scotland, Wales, and Northern Ireland for over a decade, and every batch leaves our facility with dimensional reports, material certificates, and \u2014 on request \u2014 third-party inspection documentation from accredited UK laboratories.<\/p>\n<\/div>\n<\/div>\n

Material, Working Principle & Typical Applications<\/h2>\n
\n
\n

\ud83d\udee1 Material & Construction<\/h3>\n

LH40 plates are precision blanked from high-carbon alloy steel strip, then coined to ensure plate-eye roundness and flatness tolerances within \u00b10.05 mm. Pins are precision-ground hardened alloy steel, assembled with controlled press-fit interference to prevent rotation under cyclic loading. All components undergo shot-peening for improved fatigue resistance, and a controlled-thickness rust-preventive oil coat is applied before packaging \u2014 meeting the long sea-freight shelf-life requirements of UK buyers.<\/p>\n<\/div>\n

\n

\u2699 Working Principle<\/h3>\n

Unlike roller chains or transmission chains, a leaf chain functions purely as a tensile link \u2014 it carries load rather than transmitting power. Each link set articulates around the pin axis, allowing the chain to flex over sheaves and anchor points as the mast carriage rises and descends. The interleaved plate lacing distributes the tensile load evenly across all bearing surfaces, which is why correctly specified lacing width has such a profound effect on fatigue life under the repetitive shock loads typical of UK logistics operations running two- or three-shift patterns.<\/p>\n<\/div>\n
