The present invention involves a narrow aisle truck comprising: a vehicle body having length and width directions; wheels assigned to the vehicle body and arranged on two axes running in the width direction and configured to drive and steer the truck; a drive system configured to exert an acceleration torque on at least one of the wheels; a mast extending substantially vertically with respect to the length direction of the vehicle body between the two axes; at least one detection unit to detect at least one state parameter; at least one actuator to cause a movement of the mast relative to the vehicle body; and a control unit to: determine a current state, determine an effect of an actuation of the at least one actuator on the current state, and activate the at least one actuator to reduce a difference between the determined current state and a predetermined target state.

Narrow aisle truck with measures for preventing mast vibrations and for compensating for mast deformations

The invention relates to an industrial truck comprising a mast, a load-carrying apparatus, which can be moved upwards and downwards thereon and which has at least one load-receiving assembly for receiving a load that is to be transported, and a support structure connecting the load-receiving assembly to the mast, the load-receiving assembly having a load-carrying arrangement connected to the support structure, and a device for reducing vibrations, characterised in that the device for reducing vibrations has at least one load support, which covers the load-carrying arrangement at the top at least in regions, on which support a load received by the load-carrying apparatus can be supported and which support is provided so as to be movable to a limited extent on the load-carrying arrangement such that it can perform vibration-reducing movements relative to the load-carrying arrangement.

Industrial truck comprising a device for reducing vibrations

The invention relates to an electrically powered industrial truck, in particular a narrow aisle forklift truck, comprising a battery box for housing a battery block, which box is open on at least one side for removing the battery block in the width direction of the vehicle and comprises on its top face a strut extending substantially in the longitudinal direction of the vehicle, and at least one locking device for the battery block housed in a battery box, wherein the at least one locking device comprises a mount associated with the strut, a pivot shaft, which extends above the battery box in the width direction of the industrial truck and is pivotally held by the mount, and a pivot lever, which is carried by the pivot shaft and is pivotable between a locking position and a releasing position, wherein the pivot lever is designed, when in its locking position, to support the battery block in the width direction of the vehicle and, when in its releasing position, to release the battery block in the width direction of the vehicle.

Battery lock

The invention relates to an industrial truck comprising a vehicle body (); a mast () that extends substantially vertically and is rigidly connected to the vehicle body () or hinged to the vehicle body (), the mast () being associated with a load-carrying apparatus such that said apparatus can be moved upwards and downwards on said mast, which load-carrying apparatus comprises at least one load-receiving means for receiving a load that is to be transported; and an outrigger (), the longitudinal axis (L) of which extends between a first fastening point () on the vehicle body () and a second fastening point () on the mast (), the second fastening point () being associated with a vertically upper side of the mast (). In this case, the outrigger () is associated with an apparatus for reducing vibrations () which is designed to reduce vibrations acting in the direction of the longitudinal axis (L) of the outrigger ().

Outrigger comprising an apparatus for reducing vibrations

An industrial truck is described, such as a tri-lateral sideloader, comprising a truck body, wheels connected to the truck body by wheel suspensions, a mast, a plurality of operating components designed to carry out operating functions of the industrial truck, a control unit designed to actuate the operating components, and a detection apparatus designed to detect an operating parameter and/or a parameter of the environment. Here, the industrial truck further comprises a prediction unit designed to predict the occurrence of vibrations on the industrial truck based on data provided by the detection apparatus and to provide prediction data to the control unit. Based on the prediction data, the control unit is further designed to adapt the actuation of at least one of the operating components and/or to actuate an apparatus for reducing vibrations such that the vibrations predicted by the prediction unit are reduced.

Proactively reducing vibrations in an industrial truck

An industrial truck is described, the industrial truck comprising a chassis,

The invention relates to an industrial truck comprising a mast, a load-carrying apparatus, which can be moved upwards and downwards thereon and which has at least one load-receiving assembly for receiving a load that is to be transported, and a support structure connecting the load-receiving assembly to the mast, the load-receiving assembly having a load-carrying arrangement connected to the support structure, and a device for reducing vibrations, characterized in that the device for reducing vibrations has at least one load support, which covers the load-carrying arrangement at the top at least in regions, on which support a load received by the load-carrying apparatus can be supported and which support is provided so as to be movable to a limited extent on the load-carrying arrangement such that it can perform vibration-reducing movements relative to the load-carrying arrangement.

Industrial truck, in particular a tri-lateral sideloader, comprising a chassis (), a mast () arranged on the chassis (), a cab (), a support structure () supporting the cab (), which can be moved up and down on the mast () together with the cab () and has at least one cantilever arrangement () projecting from the mast (), which arrangement extends underneath the cab () and supports a load-carrying assembly () arranged in front of the cab (),and a device for reducing vibrations having vibration components transverse to the main direction of travel (G) of the industrial truck, which device allows vibration-reducing movements of the load-carrying assembly () relative to the mast (),characterized in thatthe cantilever arrangement () has a division, having a first cantilever portion (), which is coupled to the mast () and guided thereon in a height-adjustable manner, as a first part, and having a second cantilever portion (), which supports the load-carrying assembly () and is connected to the first cantilever portion (), as the other part, such that, together with the load-carrying assembly (), it can perform vibration-reducing movements relative to said first cantilever portion, in particular having movement components transverse to the main direction of travel (G) of the industrial truck.

Embodiments include an industrial truck comprising a chassis, which is supported by at least two front wheels and by at least one rear wheel, a mast for a load-carrying apparatus, wherein the front wheels are rotatably arranged on wheel arms that protrude forwards from the mast support region of the chassis, and configured for suppressing and reducing vibrations, wherein at least one of the wheel arms, is split into at least two wheel arm portions, which are mounted by a bearing arrangement so as to be able to perform movements relative to one another, wherein relative movements of the wheel arm portions are influenced, in order to suppress or reduce vibrations.

Industrial truck comprising means for suppressing and reducing vibrations

The invention relates to an industrial truck, in particular a tri-lateral stacker. The industrial truck may include a lateral pusher having a degree of freedom of movement that is oriented laterally, transversely to the main direction of travel of the industrial truck, and a lateral push drive device that can be controlled by a control device of the industrial truck for moving the lateral pusher along a lateral push frame. The industrial truck may include a device for reducing transverse vibrations, such as vibration components that are transverse to the main direction of travel of the industrial track. In a vibration-damping operating mode, the lateral push drive device can be operated as a component of the device for reducing vibrations, wherein the device allows the lateral pusher to move relative to the lateral push frame so as to reduce vibrations.
