QU100 Crane Rail 89.0kg/m YB/T 5055 Heavy Duty Crane Rail

QU100 rail (89.0kg/m crane runway rail) is a heavy-load crane runway rail in accordance with YB/T 5055 standard, widely selected for heavy industrial crane projects worldwide. Designed with large cross-section to bear high wheel pressure and repeated impact loads, it features excellent structural stability, fatigue resistance and wear performance. U71Mn is the regular supply grade, and U75V is optional for projects with higher fatigue requirements.
