The operation sequence for replacing wheel components while driving is as follows:

Remove the connecting bolts of the wheel shaft end coupling of the crane; Next, the sturdy bolts connecting the wheel group angular bearing box and the end beam were removed; After disassembling the bolts, use a lifting screw or jack to lift the crane bridge, so that the wheel tread is at a certain distance from the top of the track. At the same time, pry the wheel assembly and pull it out along the track surface for removal and replacement. Lift the pre assembled, new active wheel set with shaft end gear coupling half body onto the crane track; Push the wheel assembly closer to the installation position, while adjusting the top to slowly lower the vehicle body, and tighten the fastening bolts to ensure the safety of the operation. At this point, you can tighten the horizontal bolts appropriately, and then tighten the vertical bolts accordingly. Align the screw holes of the half body of the gear coupling at the wheel shaft end with the half body of the driven shaft coupling of the reducer, insert the connecting bolts and make them firm; After everything is normal, just drop the car body down.
