Claims18
A mobile floor levelling vehicle for levelling an undulating floor surface, which floor levelling vehicle comprises
- a vehicle body with a front and a back and a first and second longitudinal side,
- displacement means for moving the vehicle, comprising front displacement means mounted to the front of the vehicle body and back displacement means mounted to the back of the vehicle body;
- a first vehicle driving for driving the movement of the displacement means
- at least one grinding tool mounted to the vehicle body, the grinding tool being provided to contact the floor surface that needs to be levelled and to remove an amount of material from the floor to achieve the desired degree of levelling, the movement of the grinding tool being driving by a second driving, characterised in that
- the front displacement means comprise a first and second oblong front displacement member mounted respectively to the opposite first and second longitudinal sides of the vehicle body, which first and second front displacement member extend in longitudinal direction of the vehicle and are rigid in longitudinal direction
- the back displacement means comprise a first and second oblong back displacement member mounted respectively to the first and second longitudinal side of the vehicle body in cross direction thereof, the first and second back displacement members extending in longitudinal direction of the vehicle
- wherein the first front and back displacement member are mounted to a first rigid longitudinally extending axis of the vehicle body, and the second front and back displacement member are mounted to a second rigid longitudinally extending axis of the vehicle body,
- wherein the first front and back displacement members on the one hand and the second front and back displacement members on the other hand are provided to move over a same track
- wherein the back displacement members are provided to move over a track that has been levelled by the at least one grinding tool,
- wherein the front and back displacement members are tiltable with respect to the vehicle body in longitudinal direction of the vehicle.
