What Is the Size of CR100 Rail?
The JIS CR100 crane rail has a height of 150 mm, head width of 120 mm, base width of 155 mm, and web thickness of 39 mm. Its theoretical weight is 100.20 kg/m (67.33 lb/ft). Manufactured in accordance with JIS E 1101 and JIS E 1103, CR100 is designed for heavy-duty crane runway systems in ports, steel mills, shipyards, logistics terminals, and other industrial facilities with high wheel loads.
JIS CR100 Rail Dimensions & Technical Specifications
The CR100 profile is designed to provide high load-bearing capacity, stable wheel contact, and long service life in demanding crane applications. Its wide rail head helps distribute wheel loads more evenly, reducing contact stress and rail wear, while the robust web and base improve structural strength and installation stability.
Choosing the correct rail profile is critical for crane stability, wheel contact performance, and long-term service life. GNEE RAILWAY RAILWAYL supplies JIS CR100 crane rails with EN 10204 3.1 Mill Test Certificates (MTC), optional third-party inspection, custom rail processing, corrosion protection, and compatible fastening systems for international infrastructure and industrial projects.
How Does CR100 Crane Rail Compare with Other Crane Rail Standards?
JIS CR100 is frequently compared with crane rail profiles specified under DIN 536 (Germany), GB/T (China), and GOST (Kazakhstan) when selecting or replacing heavy-duty crane rails. Although these standards are intended for similar crane runway applications, they differ in profile dimensions, cross-sectional geometry, theoretical weight, and technical specifications. As a result, rail profiles from different standards are not directly interchangeable, and compatibility should be verified based on the original track design, crane wheel dimensions, fastening system, and load requirements.
| Standard Profile | Height (mm) | Base Width (mm) | Head Width (mm) | Web Thick. (mm) | Weight (kg/m) |
|---|---|---|---|---|---|
| JIS CR100 (Japan) | 150.0 | 155.0 | 120.0 | 39.0 | 100.20 |
| Chinese QU100 (GB) | 150.0 | 150.0 | 100.0 | 38.0 | 88.96 |
| Chile GOST KP100 | 150.0 | 150.0 | 100.0 | 38.0 | 89.00 |
| DIN 536 A100 (Germany) | 95.0 | 200.0 | 100.0 | 60.0 | 74.30 |
| DIN 536 A120 (Germany) | 105.0 | 220.0 | 120.0 | 72.0 | 100.00 |
Compared with QU100 (GB/T) and KP100 (GOST), the JIS CR100 rail has a 120 mm head width and a theoretical weight of 100.20 kg/m, while QU100 and KP100 have a 100 mm head width and a theoretical weight of approximately 88.96 kg/m. These dimensional differences may affect wheel contact, fastening compatibility, and rail installation.

Where Is JIS CR100 Crane Rail Used?
The JIS CR100 crane rail is designed for heavy-duty crane runway systems requiring high load capacity, stable wheel contact, and long service life. Manufactured from high-strength U71Mn rail steel, CR100 provides good wear resistance, high bending strength, and reliable performance under frequent wheel loading conditions. With its large rail profile and heavy linear weight of 100.20 kg/m, CR100 is commonly used in industrial facilities where continuous crane operations and heavy wheel loads are required.
- Port & Container Terminals: CR100 rails are used for Ship-to-Shore (STS) container cranes, Rail-Mounted Gantry (RMG) cranes, and other large-scale container handling equipment where stable crane travel and precise rail alignment are required.
- Steel Mills & Foundries: CR100 crane rails are applied in overhead traveling cranes, ladle cranes, and material handling systems for transporting steel products, molten metal containers, and heavy industrial loads.
- Shipyards & Maritime Facilities: CR100 rails support Goliath cranes, gantry cranes, and shipbuilding lifting systems used for large component positioning, hull assembly, and heavy fabrication operations.
- Mining & Bulk Material Handling: CR100 rails are suitable for stacker reclaimers, heavy transfer vehicles, and bulk handling crane systems in mining, ports, and large industrial storage facilities.
Frequently Asked Questions (FAQs) About CR100 Rail Size
Q1: What are the dimensions of CR100 rail?
A: The JIS CR100 crane rail has a height of 150 mm, head width of 120 mm, base width of 155 mm, and web thickness of 39 mm. Its theoretical weight is 100.20 kg/m (67.33 lb/ft).
Q2: Can CR100 rail be welded?
A: Yes. CR100 rail can be welded using aluminothermic (thermite) welding or flash butt welding. Proper welding procedures, including pre-heating and controlled cooling, are required to ensure joint quality.
Q3: What is the difference between CR73 and CR100 rail?
A: CR73 and CR100 are both JIS crane rails, but CR100 has a larger profile and higher weight.
- CR73: 135 mm height, 73.30 kg/m weight
- CR100: 150 mm height, 100.20 kg/m weight
CR100 is generally selected for crane systems requiring higher wheel loads and greater structural capacity.
