<p>A transport vehicle with a liftable and lowerable platform (6) for loads has at least three lifting cylinders (3) for the platform (6), the said cylinders (3) being supported on a chassis and engaging in an articulated fashion on the chassis and on the platform (6) or on an intermediate platform (5) to which at least two guide pins (4) which are guided in or on the chassis in the vertical direction are connected in an articulated fashion, at least one guide pin or one articulation point of the guide pin on the platform (6) or intermediate platform (5) being displaceably mounted in the direction of the connection line (11) of the axes of the guide pins (4) by means of the bearing point (12). In order to monitor the stability, in particular the tilt resistance, of a load located on the transport vehicle, the lifting cylinders (3) and the pressure lines of the said cylinders (3) are connected to pressure sensors and the pressure measurement values are fed to a processor, in particular a comparator. When the pressure drops below a set value in a lifting cylinder (3), the pressure medium source is connected to this lifting cylinder (3) to adjust the actual pressure value to the set pressure value. <IMAGE></p> |
