Abstract
Tiller truck provided with force transferring means in order to transmit a pumping movement with the tiller (1) to the wheels via a coupling in order to facilitate the movement of the truck when this runs heavily due to a great load and/or uneven ground. The coupling is so arranged that it can be set for force transfer forward or rearward or in an entirely free position. A control (26) for the control of the coupling is arranged in the tiller handle.
Claims18
Tiller truck provided with a force transfer mechanism and coupling for the transfer of a pumping tiller movement to a drive movement for the steering wheels, wherein the coupling is so arranged that it has three control positions, one the driving entirely free coupling position and two in opposite directions drive force transferring positions while movement of the tiller in the opposite direction of a set drive force transferring turning direction allows free movement without force transfer of the tiller and that the wheels can rotate freely in the drive force transferring direction.
