Product Introduction
GB The high-precision dimensions of crane rails are the key to ensuring the stable operation of lifting equipment. Taking the QU series as an example, the rail height, bottom width, waist thickness and other parameters of each specification from QU70 to QU120 are strictly controlled within the tolerance range. The rail height error does not exceed ±0.5mm, and the bottom width error is ±1mm. This high-precision design makes the clearance between the crane wheel and the rail extremely small, effectively reducing the lateral shaking and rail gnawing during operation.
GB crane rails mainly include QU70, QU80, QU100, and QU120.
Size:
QU70: rail height 120mm, bottom width 120mm, head width 70mm, waist thickness 28mm.
QU80: rail height 130mm, bottom width 130mm, head width 80mm, waist thickness 32mm.
QU100: rail height 150mm, bottom width 150mm, head width 100mm, waist thickness 38mm.
QU120: rail height 170mm, bottom width 170mm, head width 120mm, waist thickness 44mm.
Length specifications: Standard lengths are 9m, 9.5m, 10m, 10.5m, 11m, 11.5m, 12m, 12.5m;
Scope of application:
