Moving apparatus to move a wheeled vehicle (1) on a surface (2). The vehicle is e.g. a motor vehicle, trailer or airplane on an airfield and the surface (2) is e.g. ground, road, airfield, floor of a building, loading platform, back of a truck or railway truck. The moving apparatus consists of a drive wheel (4) rotated by a motor (3) and a pressing device (5) attached to it directly or indirectly to press the drive wheel against the wheel (6) of the vehicle to be moved. The vehicle (1) is moved by rotating its wheel (6) by means of the drive wheel (4). According to the invention the pressing device (5) of the drive wheel (4) of the moving apparatus consists of at least two friction wheels (8) connected to each other with connecting members (7), of which friction wheels (8) at least one is a drive wheel rotated by a motor (3). At least one of the firction wheels can be moved by means of the connecting members so that the friction wheels are pressed on different sides against the wheel (6) or group of wheels (6 and 10) formed by a bogie of the vehicle to be moved. The moving apparatus can include at least one ground wheel (11) resting on the surface (2), which ground wheel is freely turning at least while the moving apparatus is being used to move the vehicle to be moved. |
