Product Application
QU70 Rails Project Applications
Packaging & Delivery Assurance
Steel belts and steel wires for fixing
Steel wires and steel belts play a key role in the packaging and transportation of rails. Steel wires are used to tightly fix multiple rails into bundles by winding and tying them together to prevent the rails from being displaced or damaged by collisions during transportation; steel belts, with their strong rigidity and wrapping properties, reinforce the outer layer of the rails and form a protective frame on the outside of the rail bundle to protect the rail surface from scratches, extrusion, and other damage.
Wooden box protection
Since rail accessories (such as fasteners, bolts, gaskets, etc.) have various specifications and shapes, wooden boxes can be customized with partitioned linings according to the size and characteristics of the accessories, and the gaps can be filled with cushioning materials such as foam and corrugated paper to classify and fix different accessories to avoid thread damage, surface scratches or scattered parts due to collisions during transportation.
Common Problems of QU70 Crane Rails
Does the rated load of the QU70 rail match the maximum lifting weight of the crane?
The design load capacity of the QU70 rail is 10-30 tons (the specific load capacity needs to be calculated in combination with the crane wheel pressure). To ensure safety, please provide your crane model and maximum lifting weight, and we will check the load matching.
Does the QU70 Rail height, bottom width, head width, etc. meet the national standards?
Yes, QU70 rail is strictly produced according to the national standard, and we can provide the test report and standard parameter table.
Is non-standard length available to reduce on-site welding joints?
Customization is supported! The standard length is 12m, but non-standard lengths such as 6m/9m can be provided to reduce welding points and installation costs.
Is the QU70 Crane Rail made of high-strength wear-resistant steel?
QU70 track is made of U71Mn high-strength wear-resistant steel with a hardness of HB260-320 and a tensile strength of ≥880MPa, which is suitable for heavy loads and frequent use scenarios.
