For the wheel set replacement method and process has been a problem that needs attention, the following, for you to list in detail the replacement of lifting accessories in the wheel set of steps:

① Remove the connecting bolts of the coupling at the end of the wheel axle.

② Remove the fastening bolts connecting the angular bearing box of the wheel set and the end beam.

③Use crane lifting screw or jack to lift the crane bridge, so that the wheel tread surface from the top surface of the track about 10 mm or so, pry the wheel set and pull it out along the track surface in order to unload the replacement.
