Mountable wheel arrangement

The attachable wheel unit (17) for connecting to a transporting device has a fork-form bolster (20) to accommodate the axle (18) of a running wheel (19), a support bracket (24) to accommodate a coupling element (25) for the connection to the transporting device and for connection to the axle bolster, and a damping device (30) acting between the support bracket and the axle bolster. The coupling element serves for the connection of the axle bolster to the support bracket.
