Crane Rail QU70 QU80 QU100 QU120 | U71Mn Material | GB3426 Standard | For Overhead Crane & Port Machinery
GB Standard QU Series Crane Rail for Overhead Crane & Port Machinery
Our QU series crane rails are specially designed for heavy-duty lifting equipment, manufactured from high-quality U71Mn manganese steel in strict accordance with GB/T 3426 and YB/T 5055-2014 standards. With rail head widths ranging from 70mm to 120mm and unit weights from 52.80 kg/m to 118.10 kg/m, these rails are engineered to withstand the extreme wheel loads, lateral thrusts, and cyclic contact stress of overhead travelling cranes, port gantry cranes, and heavy machinery workshops.
