DGMC-16JS Rail Grinding Machine with Hybrid Dual-Power From Diesel and Catenary

DGMC-16JS is applicable to rail grinding of standard track gauge line. This machine is composed of two cars (A car + B car) which are connected by rigid drawbar, and the power source for the complete vehicle is from the metro CATENARY electric energy and self-contained internal combustion generator unit. Both of the two power sources are able to drive the complete vehicle traveling and grinding. Based on advanced computer network control technology, and through control of the grinding mechanism and the complete vehicle, the machine is able to grind the rail head surface by means of high-speed rotating grinding wheels driven by motor during operation at low constant speed, recover the contour shape of rail cross section, improve the longitudinal smoothness of rail, eliminate the defects such as rail surface corrosion, fatigue cracks, corrugation, wear, deformation, speckles and fins, and prolong the service life of rail.
