QU70 Rail
QU70 rail is named after its 70 mm head width and manufactured to YB/T 5055-2014 standards. Featuring equal height and base width with a thick web, this compact design offers solid bending resistance. Made primarily from U71Mn manganese steel and weighing 52.8 kg/m, QU70 is ideal for medium-duty cranes—such as bridge and gantry cranes—in industrial facilities and smaller terminals where lifting demands are moderate.
- Strong Bending Resistance
- Durable Manganese Steel
- Ideal for Medium-Duty Cranes

QU70 Rails Project Applications
Medium Cranes
Ideal for bridge and gantry cranes in industrial workshops. QU70 rail supports steady movement under moderate loads, especially where cargo flow is stable and working conditions are not excessively demanding.
Light Port Duty
Used at small to mid-size port terminals where traffic is light. It enables smooth crane operations without overloading the rail system, maintaining reliability in container or bulk handling.
Workshop Use
Perfect for factory settings where overhead cranes operate on fixed routes. The rail’s balance between strength and size helps ensure durability in general industrial lifting tasks.
