Product Introduction
GB crane rails are products under national standards and specifications. They are special rails with precise dimensional accuracy and good surface quality. They are used for crane track laying, can effectively reduce running resistance, and extend the service life of cranes.
QU80 crane rails have a rail height of 130mm. This height design effectively disperses the vertical pressure generated by the crane during operation while ensuring the overall rigidity of the rail; the bottom width is also 130mm. The wide bottom is like a solid base, which enhances the contact area between the rail and the foundation, provides stable support, and reduces shaking during operation; the head width is 80mm, which provides a perfect contact area for the crane wheels, which not only ensures the load-bearing capacity, but also reduces the wear between the wheels and the rails; the waist thickness is 32mm, which further strengthens the structural strength of the rail, making it less likely to deform when facing heavy load impact. These dimensional parameters cooperate with each other, making the theoretical weight of each meter of QU80 rail about 64.41kg, building a strong load-bearing structure that can stably support the lifting of 50-100 tons of heavy objects.
The U71Mn material has undergone a special heat treatment process, which greatly enhances the hardness and wear resistance of the track surface. In high-frequency crane use scenarios such as ports and mines, even after tens of thousands of wheel rolls, the QU80 track can still maintain a good surface morphology, reducing maintenance frequency and lowering corporate operating costs.

Product Application
Product Packaging & Delivery
Generally, steel strips or steel wires are used to bundle rails, usually at regular intervals (e.g., 2-3 meters) to ensure that the rails do not collide or slide against each other during transportation. For longer rails, additional protective pads, such as rubber pads or wooden boards, may be required at both ends and in the middle of the rails to prevent the steel strips or wires from damaging the rail surface.
