QU120 Rail

QU120 Rail for Extreme-Duty Crane Systems

Product Overview

QU120 rail is a premium crane rail profile developed for extreme-duty lifting systems, where wheel loads, impact forces, and service cycles exceed the limits of conventional QU series rails.

With its 120 mm rail head and reinforced web geometry, QU120 rail is engineered to maintain structural stability, alignment accuracy, and surface integrity under continuous heavy operation. It is particularly suited for mega gantry cranes, ship-to-shore cranes, steel mill cranes, and bulk material handling systems, where downtime is costly and safety margins are non-negotiable.

Manufactured in accordance with YB/T 5055-2014, GlorySteelWork supplies QU120 crane rails for projects that demand maximum load tolerance and long-term operational reliability.

QU120 Crane Rail Materials

QU120 rails are produced using U71Mn high-carbon rail steel, selected specifically for high wheel pressure, frequent impact loading, and fatigue-intensive environments. For special applications, higher-strength or project-specific steel grades can be customized to meet unique load, wear, or service-life requirements.

Material advantages include:

High tensile strength and resistance to plastic deformation
Excellent wear resistance under large-diameter crane wheels
Strong fatigue performance for long service cycles
Stable hardness distribution for predictable rail head behavior
Through controlled rolling and cooling processes, the steel achieves a consistent internal structure that supports long-term track stability under extreme loads.
