Method for operating a transport vehicle having two drive wheels and two support wheels for the interference-free transport of load shelves in factory buildings in a partially autonomous driving mode, the method comprising the following features: a) a control centre in a storage area receives the order to ensure that a load shelf having transported goods located thereon is transported to a destination; b) the control centre determines which transport vehicle , based on its current location and its present order status, is capable of handling the required order the fastest; c) the transport vehicle subsequently receives from the control centre the order to seek the load shelf in a region of a comparatively large surface of a storage area, to pick up the load shelf , and to drive the load shelf having the transported goods located thereon to the destination; d) the transport vehicle selected by the control centre receives from the control centre route instructions pertaining to the route to be travelled and the speed to be travelled in each section of the route, which route instructions are determined by means of a specific route algorithm, in order to reach the destination in a specific time window; e) the transport vehicle determines the load shelf to be picked up by means of a 3D-sensor, chooses a suitable initial position for picking up the load shelf , drives below the latter and lifts it for transporting, characterized in that the load shelf can be lifted and lowered by means of two front and two rear lifting rods of the transport vehicle by way of a control member ; a centre of gravity of the load shelf is determined by means of sensors; the result of such a centre-of-gravity determination is used for actuating additional control members for the front and the rear lifting rods of the transport vehicle , wherein the actuation of the additional control members takes place separately and independently of lifting and lowering the load shelf; and the two drive wheels are in each case pushed onto a floor area by a spring element by way of an angular lever . a) a control centre in a storage area receives the order to ensure that a load shelf having transported goods located thereon is transported to a destination; b) the control centre determines which transport vehicle , based on its current location and its present order status, is capable of handling the required order the fastest; c) the transport vehicle subsequently receives from the control centre the order to seek the load shelf in a region of a comparatively large surface of a storage area, to pick up the load shelf , and to drive the load shelf having the transported goods located thereon to the destination; d) the transport vehicle selected by the control centre receives from the control centre route instructions pertaining to the route to be travelled and the speed to be travelled in each section of the route, which route instructions are determined by means of a specific route algorithm, in order to reach the destination in a specific time window; e) the transport vehicle determines the load shelf to be picked up by means of a 3D-sensor, chooses a suitable initial position for picking up the load shelf , drives below the latter and lifts it for transporting, the load shelf can be lifted and lowered by means of two front and two rear lifting rods of the transport vehicle by way of a control member ; a centre of gravity of the load shelf is determined by means of sensors; the result of such a centre-of-gravity determination is used for actuating additional control members for the front and the rear lifting rods of the transport vehicle , wherein the actuation of the additional control members takes place separately and independently of lifting and lowering the load shelf; and the two drive wheels are in each case pushed onto a floor area by a spring element by way of an angular lever . <EOS>
