Abstract: The invention relates to a method and device for controlling a combined rotary/push movement of a load-receiving means of an industrial truck, in particular a three-way stacker, both the rotary movement and the push movement being brought about by means of respective hydraulic elements (32, 34), which are supplied with hydraulic fluid by a single hydraulic pump (22) which is driven by an associated pump motor (24), and a performance characteristic of the hydraulic pump (22) being controlled according to a predetermined progression over time during the rotary/push movement; the industrial truck comprising a valve assembly (30) which is designed to be operated such that, below a threshold value for the hydraulic pressure provided by the hydraulic pump (22), only the rotary movement of the load-receiving means is brought about, while, above the threshold value, both the rotary movement and the push movement are brought about.

Abstract: A steering system has a wheel (38) which rolls on an underlying surface (U) and which can be steered about a wheel steering axis (34) which is orthogonal with respect to the underlying surface (U), the rolling direction being determined by a wheel steering angle which describes the rotational position of the wheel (38) about the wheel steering axis (34). Furthermore, the steering system has a steering force coupling-in part (13) for coupling a steering force into the steering system and a steering force transmission device (28) for transmitting the steering force to the wheel (38), and, furthermore, a steering angle limiting device (40, 42a, 42b, 50) which can be switched between an active state and an inactive state, limits the wheel steering angle at least to a wheel steering angle range in the active state and does not limit the wheel steering angle of the wheel (38) in the inactive state.
