PGM-48 Rail Grinding Train

The machine is used to correct the rail corrugation and wheel-rail bum, correct the track side tilting deformation and repair the defect on wheel-rail contact surface and other rail defects caused due to vehicle running on rail. It can also be used for preventive maintenance of rails. The grinding machine is composed of No. 1 car (control), No. 2 car (living) and No. 3 car (end). Each car has 8 grinding heads, and the whole vehicle has 48 grinding heads in total. The minimum working curve radius of the grinding car is 180m. When the working speed is 7km/h, the metal removed every time is 0.2mm. The machine is equipped with 6 dust collection units, and each unit composes an independent dust colledbn system, with total power of 90kW. The dust collection system is designed with three cleaning modes, i.e. differential pressure cleaning, start-up cleaning and shutdown cleaning.
