Disassembling the powered wheel

If the wheel is damaged or worn, it must be replaced by a new wheel.

 

The figures show the disassembly of a size 130 wheel. The removal of larger wheels does not essentially differ from this.

*   Take out the bearing bolt, bearing flange and wheel.

 

Note:

Only for size 420 with crane travel drive 420 V: An adapter is also inserted on the bearing flange. If this cannot be easily taken off, it can remain on the bearing flange when the wheel is removed.

 

Tip:

To be able to easily remove the bearing flange from the end carriage, screw two or four screws in the corners of the bearing flange and thereby press the bearing flange off the end carriage.

 

 

Only with size 500

This work step applies only to end carriages of size 500.

 

Tip:

 

 

Threaded holes

 

Bearing bolt

To be able to remove the bearing bolts more easily, insert two screws into free threaded holes on the bearing bolt, opposite each other. This makes it easy to push the bearing bolt out of the end carriage.
