Product Introduction
QU120 Crane Rail is a high load capacity rail designed for heavy duty cranes. It is made of high carbon steel U71Mn with tensile strength of ≥880 MPa, excellent wear and fatigue resistance, and is suitable for frequently impacted operating scenarios.
QU120 rail length are furnished from 6-12meter. Other lengths are available upon request from GNEE RAIL. Steel Grade are produced to various qualities and specifications as required by our clients.
Product Specifications
The QU120 track has a large cross-section and strong rigidity. Its rail head width is 120mm, rail height is 170mm, bottom width is 170mm, and the theoretical weight is as high as 118kg/m.
Product Application
The QU120 rail is a heavy-duty crane rail widely used for large ship-to-shore cranes (STS), rail-mounted gantry cranes (RMG), and rail-mounted transport systems. Its exceptional load-bearing capacity and stability make it ideal for intensive container handling operations, withstanding extreme wheel loads and harsh coastal environments.
QU120 Structural Characteristics and Load-bearing Advantages
The QU120 rail features a thicker cross-section, a greater moment of inertia, and significantly improved bending strength, enabling it to withstand high vertical loads and complex lateral stresses. Its optimized rail base width increases the contact area and more evenly distributes foundation stress, effectively reducing track subsidence and gauge deviation.
How do I select the right QU model for my crane's tonnage?
A: Refer to rail head width and load capacity:
QU70 (70mm rail head): Ideal for 5–50-ton light/medium cranes (e.g., workshop bridge cranes using QU70 heavy duty crane rail for industrial workshop).
QU80 (80mm rail head): Suited for 50–100-ton medium cranes (e.g., port gantry cranes requiring overhead crane rail QU70).
QU100 (100mm rail head): Designed for 100+ ton heavy cranes (e.g., metallurgical casting cranes demanding high strength crane rail for molten metal transport).
Note: Match wheel tread width (typically 10–20mm wider than rail head) and operating speed. Free load calculation services are available.
As a famous QU120 rail supplier in China, GNEE RAIL keeps a large number of QU120 rails in stock all the year round.
