<p>The object of the invention is a transfer device that grips one or more wheels (6), which is intended to move an aircraft (1) or other wheeled device over a base, which transfer device includes two rollers (3, 4) which are placed on opposite sides of the wheel (6) and pressed against the wheel (6), at least one one of which is a friction roller (3, 4) driven by a motor, pressure devices (2) to create the aforementioned pressure, and three or more support wheels (7, 8) for the independent movement of the transfer device. The intention of the invention is to create a transfer device the power transmission required for the independent movement of which is simple and reliable. According to the invention the transfer device's own wheel (8) or an auxiliary wheel that drives it is located in the track of movement of the friction roller (4), in which case the friction roller (4) is operationally pressed alternatively against either the aircraft's wheel (6) or the transfer device's own wheel (8) to transmit drive to one or other of these.</p> |
