Proven Schöberl wheel dolly with directional control on two swivel castors. In addition to existing advantages, it is now possible to lock two wheels for straight-line travel. Thereby, a vehicle can be easily loaded or unloaded since lateral rolling, e.g. on a slope is prevented. However, it is possible to turn the vehicle 360 ° when the locks are released. Attachments in various sizes can be used to manoeuver vehicles without wheels.
