Abstract: A hydraulic steering device (1) of a mobile machine, in particular of an industrial truck, includes a steering angle transmitter (2) in mechanically functional communication with a steering valve (4). As a function of the actuation of the steering angle transmitter (2), the steering valve (4) controls the connection of a steering drive (13) with a pressure fluid source (6) and a reservoir (11). To vary the translation ratio of the steering device in a simple manner, a bypass device (20) is operationally associated with the steering drive (13). By activation of the bypass device, the quantity of pressure fluid delivered from the pressure fluid source (6) to the steering drive (13) can be diverted to a reservoir (11).

Abstract: An industrial truck has a vehicle frame (1) with a support section (3) that holds a battery block (4). For insertion and removal of the battery block (4), there is a lateral frame opening (3b) and a top frame opening (3a). The vehicle frame (1) has a side member (6) configured to span the support section (3). The side member (6) can be pivoted between a closed position in which it spans the support section (3) and is a component of the load-bearing structure of the vehicle frame (1) and an open position in which it allows access to the support section (3).

Abstract: An industrial truck, in particular counterbalance fork-lift truck, has a front drive axle (2) which has at least one electric drive motor and is fastened together with other components (K) to a vehicle frame (1). A component carrier (T) adjoining the drive axle (2) at the rear in the longitudinal direction of the vehicle is rigidly connected to the drive axle (2) and at least one vibration-producing and/or vibration-transmitting component (K) is fastened on the component carrier (T). The drive axle (2) with the component carrier (T) and the components (K) fastened thereon form a preassembled axle assembly, which is elastically mounted on the vehicle frame (1).

Abstract: An industrial truck has a vehicle frame (1) with a frame portion (2) having a lateral frame opening (2b) for receiving a battery block. A door (3) covers the frame opening (2b) and may be pivoted outwardly about a substantially vertical axis of rotation (A1). To allow the door (3) to be opened approximately 180°, the door (3) is connected to the vehicle frame (1) by a double hinge (5). A second axis of rotation (A2) is set apart and parallel to the first axis of rotation (A1) and is alterable in its position when the door (3) pivots about the first axis of rotation (A1). A device for obstructing a rotational motion of the door (3) about the second axis of rotation (A2) can be provided, which device can be active in the pivoting range between the closed position and an open position that is approximately at right angles.
