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.
Key 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.
Applications
Ports & Maritime
Container cranes in international ports for handling 40+ ton containers.
Ro-Ro terminals and bulk material handling systems.
Heavy Industry
Steel mills and foundries for overhead cranes transporting molten metal or heavy machinery.
Shipyards for gantry cranes in vessel assembly and repair.
Mining & Construction
Underground mining transport systems with high payload requirements.
Quarries and aggregate processing plants for mobile crane operations.
Aerospace & Automotive
Aircraft hangars for assembly line cranes handling large components.
Automotive manufacturing for heavy-duty press shop cranes.
