A150 Rail
Product Overview
DIN 536 A150 is a DIN 536-1:1991-compliant, hot-rolled heavy-duty crane rail engineered for extreme loads and the harshest industrial environments. Its oversized cross-section and premium U71Mn material deliver superior bending and torsional stiffness, outstanding wear resistance, and long service life for the most demanding lifting applications.
Key points
Industry-leading load capacity — large cross-section and high section modulus provide exceptional bending and torsional resistance for super-heavy cranes.
High wear resistance & longevity — superior surface hardness and fatigue resistance reduce downtime and life-cycle cost.
Weldable & install-friendly — designed for continuous (seamless) runs, compatible with standard welding and finishing processes; supports full-length quenching for added surface hardness.
Certified & customizable — supplied with EN 10204 3.1 material certificate; standard 12 m length with cutting and processing options (6–12 m).

Typical applications
Port and terminal cranes (quay cranes, rail-mounted gantries)
Shipyard gantry cranes and heavy lifting lines
Metallurgical plants and heavy machinery shops
Heavy-duty installation tracks for hydropower, nuclear, and large civil projects
Special heavy-haul rail (axle loads ≥ 30 t)
Installation highlights
Concrete base flatness: ≤ 3 mm per 10 m.
Anchor spacing: ≤ 1.5 m (adjust to span and load).
Vibration isolation: use 8 mm rubber pads sized to rail base.
Fastening: dedicated resilient clip / elastic bar systems recommended.
Joints: fishplates with 3–5 mm thermal/expansion gap for continuous lines.
Maintenance guidance
Daily: visual check of fastenings; clear debris.
Monthly: measure lateral/head wear (max allowed: straight runs 10 mm; curves 8 mm).
Quarterly: check alignment and foundation condition.
Annually: full inspection for deformation and material integrity.
Preventive machining: when head wear = 8–10 mm, grind away 0.3–0.5 mm to restore profile.
