Crane DRS wheel set removal method

                                           
Crane DRS wheel set removal method:
1. Lift the pre-assembled, new active wheel set with the shaft end gear coupling half to the crown of the crane.
2. Use the crane's lifting screw or jack to lift the crown bridge, so that the wheel tread is about 10mm away from the top surface of the track. Move the crane DRS wheel set and pull it out along the track surface to remove it.
4. Remove the fastening bolts connecting the angular bearing housing of the crane DRS wheel set to the end beam.
