Axle-box unit and bearings dismantling and washing system

Axle-box unit and bearings dismantling and washing system
The system for dismantling and washing axle boxes and bearings is intended for use at railway car repair factories (car depots and car wheel workshops).
The system performs the following manufacturing operations:
  •  lifting and moving the wheelset along the trestle;
  •  rotation of wheelsets at manufacturing positions;
  •  using a dismantling stand to unscrew all the bolts of the axle-box unit and M110 nut;
  •  removal of both axle-boxes from the axle of the wheel set and their transportation by means of a manipulator to the position of dismantling the bearings of the automated section for pressing-out and washing bearings and axle box housings;
  •  pressing-out of bearings from the axle box;
  •  washing of axle-box housings;
  •  washing of bearings.
