What is the Weight per Meter of CR73 Rail?
The theoretical weight of CR73 crane rail is 73.3 kg per meter (49.26 lb/yd). As a heavy-duty crane rail profile manufactured according to JIS crane rail specifications, CR73 is designed for industrial applications requiring high load capacity and long-term operational stability.
With its robust cross-sectional design, CR73 rail is commonly used for port cranes, gantry cranes, steel plant cranes, shipyard handling systems, and other heavy-duty industrial rail applications.
The weight per meter is a key parameter for crane runway design, transportation planning, and load-bearing calculations.
GNEE RAIL supplies CR73 crane rails manufactured to meet international project requirements, with support for technical document review, Mill Test Certificates (MTC), customized lengths, and export packaging solutions. Our CR73 rails are supplied for industrial applications including port cranes, steel plants, shipyards, and heavy-duty material handling systems.

CR73 Rail Technical Specifications & Dimensions
When selecting CR73 crane rail, weight alone is not enough. The rail profile dimensions must match the crane wheel system, rail fastening components, and supporting structures to ensure proper installation and long-term performance.
The following table shows the standard CR73 crane rail dimensions, including key parameters such as rail height, head width, base width, and web thickness.
| Parameter | Specification (Metric) | Specification (Imperial Equivalent) |
|---|---|---|
| Theoretical Weight | 73.3 kg/m | 49.26 lbs/yd |
| Rail Height (H) | 135.00 mm | 5.31 inches |
| Bottom Width / Base (B) | 140.00 mm | 5.51 inches |
| Head Width (A) | 74.00 mm | 2.91 inches |
| Web Thickness (S) | 22.00 mm | 0.87 inches |
The CR73 rail features a robust profile with a 135 mm rail height and 140 mm head width, providing stable support for heavy-duty crane operations. Its cross-sectional design helps improve resistance to deformation and maintain track stability under dynamic loads, such as crane acceleration, braking, and uneven wheel loading.
Frequently Asked Questions (FAQ)
Q1: Is CR73 rail the same as JIS 73kg/m crane rail?
Yes. CR73 is a JIS standard crane rail profile with a theoretical weight of approximately 73.3 kg/m. The typical dimensions include 135 mm rail height, 140 mm head width, and 100 mm base width. Always confirm the required specifications before ordering.
Q2: How is CR73 crane rail installed?
CR73 crane rail is typically installed using dedicated crane rail fastening systems, such as rail clips or clamps, mounted on steel girders or concrete foundations. Rail pads are commonly used underneath the rail base to improve load distribution and reduce vibration during crane operation.
Q3: Can GNEE RAIL supply custom lengths of CR73 rail?
Yes. Standard CR73 rail lengths commonly include 10 m and 12 m, while customized cutting lengths can be supplied according to project requirements. Customized lengths help reduce rail joints and simplify installation.
Q4: What steel grades are available for CR73 rail?
CR73 rails can be supplied in different steel grades according to application requirements, including load capacity, wear resistance, and operating conditions. Common crane rail materials include U71Mn and other high-strength rail steel grades specified for heavy-duty applications.
