What are the Applications of GB QU120 Crane Rail
Oct 14, 2025
QU120 Crane Rail is a high-strength steel rail specially designed for heavy-duty equipment and industrial transport lines, widely used in various rail systems due to its excellent load-bearing capacity, wear resistance, and impact resistance. This rail features a large cross-section, wide head, and thick web, maintaining track stability and safety under frequent heavy-load operations.

In port and terminal operations, QU120 rails are the preferred rail type for ship-to-shore (STS) cranes, rail-mounted gantry (RMG) cranes, and rubber-tired gantry (RTG) cranes. Its high-strength characteristics can withstand crane wheel loads and longitudinal impact forces, ensuring smooth start and stop of equipment, while reducing track wear and structural deformation.
In industrial plants and heavy-duty transport lines, QU120 crane rails are widely used in steel mills, mining transport lines, shipyards, and large machinery manufacturing facilities. When paired with overhead cranes or in-plant handling equipment, they enable safe and efficient heavy material transportation, while the wear resistance and fatigue strength of the rails extend service life and reduce maintenance costs.
Furthermore, QU120 rails are suitable for storage yards, automated warehousing systems, and heavy-duty track maintenance lines, ensuring long-term operational safety and reliability thanks to their stable structure and durability.
