What are the advantages of using QU120 crane rails

Oct 14, 2025

QU120 crane rail is a kind of steel rail with lower height and larger head width and waist thickness. It is used for laying the tracks of crane carts and trolley. It is mainly used for large-scale projects, ports for lifting containers, etc. for gantry cranes. Its load is 100-400tons. It is mainly applied for loading and unloading of heavy equipment and special crane rails for gantry cranes.

QU120 Crane Rail Performance Advantages

Firstly, extremely high load-bearing capacity. The QU120 rail has a large cross-section, wide rail head, and thick web, capable of withstanding concentrated impact forces from crane wheel loads and frequent start-stop operations, ensuring that the track does not undergo permanent deformation under high-load conditions, thereby enhancing equipment operational safety and stability.

Secondly, outstanding wear resistance and fatigue performance. QU120 is typically made of U71Mn high-manganese steel or high-quality alloy steel, and undergoes heat treatment and quenching processes. The rail surface has high hardness, effectively reducing wheel-rail wear and rail head flaking, extending the track service life and lowering maintenance costs.

Thirdly, strong adaptability to extreme conditions. The QU120 rail can maintain stable performance under high-frequency impacts, heavy-load operations, and low-temperature environments, resisting brittle fracture and fatigue cracking, thereby ensuring the long-term smooth operation of cranes and heavy transport equipment.

QU120 crane rail can be also used for large-scale projects, terminal hoisting containers, and laying of transportation lines for large machinery and equipment etc., and it's dedicated for gantry cranes. In addition, GNEE RAIL could also supply other crane rail specifications, like QU70 crane rail, QU80 crane rail and QU100 crane rail.
