ABSTRACT:
The excavator of the present invention has wheels which are suspended or respectively attached in a special way. When the excavator moves or is transported, the wheels are in their vertical normal position and for excavating purposes preferably all wheels are tilted sideways. This measure increases the seating surface of the excavator and therefore its stability on the ground. For this purpose, the wheels are tiltingly attached to axle extensions which can be moved in the direction of the axle. The said axle extensions are pulled in when the excavator moves, and for excavating tasks are pushed out towards the side whereby the tilting of the wheels takes place. Pistons inside the axle effect the moving of the axle extensions.
