ABSTRACT:
An industrial truck has a chassis (1), a lifting frame (5), a load holding device (10) that can move vertically along the lifting frame (5), and at least one movement device to move the lifting frame (5) relative to the chassis (1). The acceleration and/or the speed of movement of the lifting frame (5) that can be achieved by the movement device can be controlled as a function of at least one operating parameter of the industrial truck. The operating parameter is measured at least approximately continuously. One operating parameter is the current lifting height of the load holding device (10). An additional operating parameter is the weight of a load that is being held by the load holding device (10).
