What is the dimension of QU100 rail
Sep 29, 2025
The QU100 crane rail is one of the widely used heavy-duty crane rails in the GB standard. It is commonly used for port gantry cranes, large overhead cranes in metallurgical plants, and heavy-duty warehouse systems. Its cross-section is wider and thicker than standard railway heavy rails, enabling it to withstand frequent starts, stops, and high wheel pressures.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Heavy Rail | 38 KG/M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG/M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG/M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG/M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG/M | 176 | 73 | 150 | 16.5 | 60.64 | |
Standard dimensions (with minor variations depending on manufacturing tolerances) are as follows:
- Height: approx. 150 mm
- Head width: approx. 100 mm
- Base width: approx. 150 mm
- Web thickness: approx. 28 mm
- Theoretical weight: approx. 88.9 kg/m
This sectional design provides ample bending strength and fatigue resistance. It effectively distributes the impact loads from heavy crane wheels. Compared to QU70 or QU80, QU100 offers higher load-bearing capacity and wear life. It is suitable for applications with large spans, high wheel pressures, and high operating frequency. Compared to the larger QU120 specification, it offers a better balance between cost and installation convenience.
