A motor-driven truck of the type comprising a front lifting stand, first guide and journalling elements including a longitudinal stand stationary mounted on the chassis, second guide and journalling elements including a stand movable along the stationary stand, and an operator's cab supported by the movable stand and arranged to be placed in a desired position which is variable with respect to the stationary stand and to the front lifting stand as well, said first guide and journalling elements are firmly connected to the movable stand and guided by the stationary stand. The stationary stand is diagonally arranged so that it encompasses an acute angle alpha with the center line C1 of the truck and so that it extends between a rear place at the center line C1 and a front place at a front corner of the truck near one side of the lifting stand, whereby the movable stand includes a horizontal stand member located under the cab and a vertical stand member rigidly connected to the horizontal stand member and arranged close to the rear surface of the cab. The journalling elements are firmly mounted onto the under side of the horizontal stand member. The second guide and journalling elements are firmly connected to the cab and guided by the vertical stand member. Furthermore, first force-transmitting members are connected to the stationary stand and to the horizontal stand member for controlled stepless movement of the cab and the movable stand along the stationary stand, whereas second force-transmitting members are connected to the rear surface of the cab and to the movable stand for controlled stepless movement of the cab along the vertical stand member. |
