CR100 Crane Rail
Product Overview
The JIS CR100 crane rail is a premium-grade, high-strength rail designed for heavy-duty overhead cranes, gantry cranes, and material handling systems in industrial environments requiring extreme load capacity. Manufactured to JIS E 1101 and JIS E 1103 standards, it combines robust structural integrity with advanced wear resistance, ensuring reliable performance under dynamic loads and harsh operating conditions.
Precision Control ±0.1mmKey features
Rail height: 150mm ; base width: 155mm
Web thickness: 39mm; head width: 120mm.
Material:
U71Mn High-Strength Rail Steel (default): Tensile strength ≥880MPa, hardness ≥260HBW, ideal for heavy freight and high-speed applications.
Key Specifications:
Profile: Symmetrical wide-flange design (100.2kg/m)
Length:Standard: 10/12 m; custom lengths available upon request.
Heavy-Duty Load Capacity
U71Mn steel structure withstands dynamic loads and frequent start-stop operations, minimizing deformation.
Enhanced Wear Resistance
As-rolled hardness of 260–300 HBW reduces rail head wear compared to conventional carbon steel.
Microalloyed composition (0.65–0.76% C, 1.10–1.40% Mn) ensures resistance to surface fatigue and abrasion.
Precision Engineering
Tight dimensional tolerances (±0.5 mm for height/width; ±0.3 mm for head profile) ensure seamless alignment with crane wheels and fasteners.
Corrosion Protection
Optional hot-dip galvanization or epoxy coatings for outdoor applications in marine or high-humidity environments.

FAQs
Q:Length, Delivery and Surface Treatment of CR100 Rail (Common Options)？
A: Common full-length segments: 12 meters (or 8–25 meters as required). Delivery options include: bare rail, oil-coated (for rust prevention), or surface-polished/painted. The rail can be factory-treated with heat (head hardening) or full-rail hardening, with specific details subject to the purchase contract.
