QU80 RAIL
Product Overview
QU80 Rail is a heavy-duty crane rail engineered for medium-to-high load lifting systems.
With an 80 mm flat rail head and reinforced cross-section, QU80 provides reliable wheel support, improved load distribution, and long-term dimensional stability under continuous crane operation.
Manufactured to YB/T 5055-2014, QU80 crane rail is widely used in overhead cranes, gantry cranes, port handling equipment, and heavy industrial workshops where durability and precision are essential.

Material advantages include:
- High surface wear resistance under concentrated crane wheel loads
- Excellent impact toughness for frequent start-stop and reversing operations
- Stable fatigue performance under long-term cyclic stress
- Good adaptability to harsh industrial environments
Combined with controlled hot rolling and precision finishing, U71Mn steel ensures consistent rail geometry, smooth wheel contact, and extended service life.
