With a Mercedes-Benz lorry as the basic vehicle, type AT 2200-12E is optimally suited for corrugation grinding and reprofiling of grooved and Vignole rails. It is provided with a stowing space for abrasives and other operating materials. In addition, a driver’s cab for relocation travel is attached at both the front and rear. All adjustment movements of the grinding packages and the in/off tracking system are hydraulically controlled. Thanks to the small clearance profile, the grinding vehicle also functions in underground railways and tramways when the required tyres are used.
