GB The coordinated design of crane rails and lifting equipment is the key to ensuring operational safety. The rail surface profile of the QU series rails strictly matches the tread curve of the crane wheel. For example, when the arc radius of the QU100 rail head contacts the wheel of a heavy crane, the uniformity of the contact stress distribution is increased by 30%, reducing the risk of wheel slippage. At the same time, the elastic modulus of the rails is compatible with the crane suspension system, which effectively buffers the impact load during frequent starting and braking, prolongs the overall service life of the equipment, and realizes efficient linkage between the rails and the lifting equipment.
QU120 Heavy Duty Crane Rail Advantages
With a single weight of 118.5 kg per meter, it is one of the rail products with the largest cross-sectional size and the heaviest weight per meter in my country. It can withstand the huge weight of large cranes and the impact force generated by frequent lifting operations. It is suitable for heavy cranes with large lifting weight and frequent use.
It is usually made of alloy steel such as U71Mn U75V. After special production process and heat treatment, the rail surface has high hardness and strong wear resistance, which can reduce the wear between the crane wheels and the rails, extend the service life of the rails, and reduce maintenance costs.
The rail head width is 120mm and the bottom width is 170mm. This large cross-sectional size and reasonable structural design enable the rail to maintain good stability when bearing loads, and is not prone to deformation and distortion, providing reliable protection for the safe operation of the crane.
