What is the dimension of QU120 rail

QU120 crane rail is one of the highest load-bearing models in the GB crane rail series. It is designed for ultra-heavy-duty applications. These include port gantry cranes and large overhead cranes in metallurgical plants with high wheel pressures. Its cross-sectional dimensions and weight far exceed those of standard railway heavy rails.

The nominal height of QU120 rail is approximately 170 mm. The rail head width is approximately 120 mm. The rail base width is approximately 170 mm. The web thickness is approximately 32 mm. Its theoretical weight is approximately 118 kg/m. This design features a wide head, thick web, and widened base. It effectively distributes wheel pressure and impact forces during high-frequency lifting operations. This extends the service life of both the track and the wheels.

In practical engineering, selecting QU120 involves more than just single rail weight and cross-section. It requires matching with suitable rail pads, hold-down plates, anchorages, and track foundations. For example, port quayside cranes and metallurgical ladle cars often require the rails to be integrally cast with concrete foundations. This is combined with high-strength bolts or welded rail clamps. This ensures stability and long-term precision.
