DEVICE AND METHOD FOR TRANSPORTING HEAVY DUTY RACKS BY MEANS OF A TRANSPORT VEHICLE ON AN UNEVEN GROUND SURFACE
First Claim
1. A device for transporting heavy duty racks on an uneven ground surface by means of a transport vehicle, comprising the following features:
- a) a housing (3) having a carrier plate (1) for carrying and transporting a heavy duty rack (12), having two separately driven drive wheels (20) each hinged to a separate axis of rotation (5), one on each of the two sides in the center of the housing (3), and having at least one stabilizing wheel (9) at the front, and having at least one stabilizing wheel (21) at the rear,b) a transverse control arm (34), which connects the drive wheels (20), which each can be pivoted about the axis of rotation (5) by means of an angle lever (40), such that they are able to carry out vertical movements independently of one another,c) a centrally arranged actuating element (31), which can move two front lift rods (19) and two rear lift rods (16) by means of a lifting rotary lever (27) and a push rod (24) connected thereto, for raising or lowering the carrier plate (1),d) a system for supplying energy to a transport vehicle either via inductive lines laid in the ground or via stationary energy supply stations which can be driven up to,e) a control system for controlling and moving a transport vehicle within the scope of a load transportation program.

Abstract
The invention relates to a device and to a method for transporting heavy duty racks on an uneven ground surface by means of a transport vehicle, comprising the following features: a) a housing (3) having a carrier plate (1) for transporting a heavy duty rack (12), having two separately powered drive wheels (20) hinged to a respective axis of rotation (5) on both sides in the center of the housing (3), having at least one stabilizing wheel (9) in the front and at least one stabilizing wheel (21) in the back; b) a transverse control arm (34), which connects the drive wheels (20), which respectively can be pivoted about the axis of rotation (5) by means of an angle lever (40) such that they are able to carry out vertical movements independently from one another; c) a centrally arranged actuating element (31), which can move two front lift rods (19) and two rear lift rods (16) by means of a lifting rotary lever (27) and of a push rod (24) connected thereto, for raising and lowering the carrier plate (1); d) a system for supplying a transport vehicle with energy.

6. A method for transporting heavy duty racks on an uneven ground surface by means of a transport vehicle, said method having the following features:
-
a) a transport vehicle travels beneath a rack system (12) to be transported and vertically lifts this by means of an actuating element (31) and the push rods (19) and (16), moved directly vertically upwardly as a result of this movement by means of the carrier plate (1), to such an extent that the feet of the heavy duty rack (12) do not contact the ground surface during the transportation, even if the ground is uneven, and moves to the target location, b) unevennesses in the ground are compensated for during the transportation to the target location by means of the individually driven drive wheels (20) and the possibility for movement thereof about a decentrally arranged axis of rotation (5), and also the combined movement thereof via the respective angle lever (40) with a transverse control arm (34), such that the transport vehicle is subjected only to minor fluctuations, c) in the event of gradients the inclined position of the heavy duty rack is determined by means of an inclination sensor, and the horizontal position of the carrier plate (1) is corrected as necessary by means of actuating elements (17) and (18), d) upon arrival at the target location the heavy duty rack (12) is set down at the desired location by means of the lowered push rods (19) and (16). - View Dependent Claims (8, 9, 10)

7. The method as claimed in claim 7, wherein the center of gravity of the heavy duty rack (12) is detected by means of sensors, and the result of such a center of gravity determination is used to control the actuating elements (17) and (18), and in that the inclination of a heavy duty rack (12) is determined by means of an inclination sensor.
