4140 Material Steel Rail Wheels 10-1450mm Forging 0.1mm Tolerance

4140 material Customized Crane Trolley Wheels diameter from 10-1450mm Forging 0.1mm tolerance mainly used for RRV, Road-rail dual-use vehicles refer to special vehicles that can run on railway tracks as well as on general roads and even in the field. also called RRV. It was mainly used in the military in the early days. Hyundai mainly undertakes emergency tasks such as maintenance and rescue of railway lines and along the lines. Road-rail dual-use vehicles are required to be able to switch between roads and railways quickly and easily. It is usually realized by the hydraulic lane-changing slewing device on the chassis and the railway traveling guide wheel device that can be raised and lowered at any time. With the guide wheel device, the general rubber tire wheels can drive straight along the rail. Because this kind of vehicle requires a certain traction and carrying capacity, it can play a unique role in the event that the railway line is interrupted or blocked due to a disaster. Dedicated road-rail vehicles include: electric traction section catenary repair vehicles, excavators used for mountain railway repairs, emergency tractors, generator vehicles, fire trucks, fast bridge vehicles, etc.
