Crane rail is specially used for laying tracks for cranes, such as railroad cranes, overhead cranes, gantry cranes and other types of cranes. It provides a smooth and strong runway for the cranes to move forward and backward when operating heavy loads.
GNEE RAIL offers QU70 crane rail, QU80 crane rail, QU100 crane rail and QU120 crane rail with standard length 12m and U71Mn material.

The QU series rails are mainly made from U71Mn and U75V high-strength carbon-manganese steel. U71Mn offers excellent tensile and yield strength for general heavy-duty applications, while U75V provides superior performance under high temperature, corrosion, and impact conditions.
| Steel Grade | C(%) | Si | Mn | Cr | V | P | S | Tensile Strength (Rm/MPa) |
| U71Mn | 0.65~0.76 | 0.15~0.58 | 0.70~1.40 | – | – | ≤0.035 | ≤0.030 | ≥880 |
| U75V | 0.71~0.80 | 0.50~0.80 | 0.75~1.05 | – | 0.04~0.12 | ≤0.035 | ≤0.030 | ≥980 |
The QU crane rail series features high load-bearing capacity, superior wear resistance, and excellent impact strength. After hot rolling and normalizing treatment, the rail's hardness is evenly distributed, ensuring no deformation or spalling under heavy wheel pressure.QU rails are widely used in container terminals, stacker reclaimers, gantry cranes, shipyard cranes, steel plant overhead cranes, and large-scale logistics systems, providing reliable tracks for heavy lifting machinery.
In order to better serve the different needs of customers, our technical team is available to provide advice and support, helping every customer to optimize their rail selections to minimize life cycle costs. We supply suitable rail parts, like fish plates, rail clips, bolts, and nuts. We supply rail processing, like 45-degree mitre cut, welding process, milling process, special profile processing, etc. Our engineer helps customer to design railroad line according to requirements, and build mining railroad line and crane moving line. The technical support provided by GNEE RAIL can ensure that every rail we deliver provides optimum performance throughout its service life.
