What Is CR100 Rail?
CR100 Rail is a heavy-duty crane rail profile designed for industrial crane and gantry track systems requiring high load capacity and long-term operational stability. Manufactured according to JIS crane rail standards, CR100 Rail has a theoretical weight of 100.20 kg/m and a 120 mm head width, providing a larger contact area and improved load-bearing performance under heavy crane wheel loads. It is widely used in port container terminals, steel mills, shipyards, and heavy industrial facilities.
Compared with standard railway tracks, CR100 Rail features a wider head, thicker web, and broader base to withstand higher vertical and lateral forces generated by heavy-duty crane operations.
GNEE RAIL provides technical support, dimensional verification, and engineering drawing review to help customers select suitable crane rail solutions for different project requirements.

Steel Grades and Material Properties for CR100 Rail
Selecting the right steel grade is essential for achieving the required strength, wear resistance, and service life of crane rails. GNEE RAIL manufactures CR100 Crane Rail using high-strength U71Mn rail steel, which provides excellent mechanical properties for heavy-duty crane applications.
U71Mn features a minimum tensile strength of 880 MPa and a typical hardness range of 260–300 HBW, offering reliable resistance to wear, impact, and repeated wheel loads. This material selection helps CR100 Rail maintain structural stability and long-term performance in crane runway systems used in ports, steel mills, shipyards, and other heavy industrial facilities.

Common Applications of CR100 Crane Rail
Due to its heavy-duty profile and high wheel load capacity, CR100 Crane Rail is designed for demanding industrial crane systems rather than conventional railway applications. Typical applications include:
- Port Terminals: Crane runway systems for Ship-to-Shore (STS) cranes, Rail-Mounted Gantry (RMG) cranes, and Rubber-Tyred Gantry (RTG) cranes.
- Steel Mills & Metallurgy Plants: Heavy-duty crane tracks for ladle cranes, charging cranes, and material handling systems operating under high loads and frequent cycles.
- Shipyards: Runway systems for large gantry cranes used in shipbuilding and offshore structure fabrication.
- Mining & Heavy Industries: Crane and material handling systems requiring reliable performance under continuous heavy loads.

Frequently Asked Questions (FAQ) About CR100 Rail
Q1: What is the primary difference between CR73 and CR100 rails?
The main difference is the rail size and load capacity. CR73 weighs 73.30 kg/m with a 135 mm height and 100 mm head width, while CR100 weighs 100.20 kg/m with a 150 mm height and 120 mm head width. The larger cross-section of CR100 provides higher load-bearing capacity for heavier crane applications.
Q2: How is CR100 crane rail packaged for ocean shipping to prevent corrosion?
CR100 rails are bundled with heavy-duty steel straps for ocean transportation. GNEE Rail can provide anti-rust coating or protective oil treatment before shipment, using suitable export packaging methods to reduce corrosion risks during long-distance sea transport.
