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

A three-side stacker with a side push frame at one end of the stacker, on which a side arm is horizontally traversable mounted, wherein the side arm has a first traversable portion mounted on the side push frame and a second portion, which is mounted pivotally around a vertical axis on the first portion and on which a load supporting means is mounted, which is actuable by a hydraulic lifting cylinder, and a pivoting equipment for the second portion, mounted on the first portion, wherein the casing of a hydraulic rotational drive with a rotatable spindle is fixed on the first portion, wherein a portion of the spindle is splinedly connected with a holder or a lifting scaffold for the load supporting means outside the casing.

The invention relates to a steering actuation device for a vehicle, in particular for an industrial truck, having an operating element for inputting steering commands by exerting torques on the operating element, having a sensor arrangement for monitoring the steering command input state of the operating element and having a control device for converting the steering command input data detected by the sensor arrangement into control information for a steering drive apparatus of a wheel, which can be steered, of the vehicle, the sensor arrangement detecting the respective steering command input state of the operating element by means of monitoring the elastic material deformation, in particular torsion, of an element, which is subjected to elastic deformation by means of a steering command input torque on the operating element and is coupled to or associated with the operating element.

Steering actuation device for a vehicle, in particular for an industrial truck

The present invention relates to an industrial truck () having a load-receiving device () for the purpose of receiving a load (), said load-receiving device () having a clamping device () in order to hold a clamping region () of the received load () in clamping engagement, the clamping device () having at least one clamping mechanism () which can move between a clamping position and a release position, a drive arrangement (), which is coupled to at least one of the clamping mechanisms (), for the purpose of moving the clamping mechanisms () and an elastic device () which prestresses the clamping mechanisms () towards one of the positions. With the industrial truck according to the invention, provision is made for the elastic device () to prestress the clamping mechanisms () in the direction of the clamping position and to exert a clamping force on the clamping region () of the load () in the clamping position.

Industrial truck having a pallet gripper

The invention relates to an industrial truck having a mounting plate and an add-on unit, which is fixed to said mounting plate by means of at least one fixing means, a bearing surface, which points towards the mounting plate, of the add-on unit being in touching contact with a mounting surface, which points towards the add-on unit, of the mounting plate, and at least one of the surfaces (bearing surface and mounting surface) being formed such that it is curved convexly at least in the section of the touching contact.

Industrial truck having an add-on unit

In the case of an industrial truck having a piston/cylinder arrangement (), comprising a cylinder () and a piston (), which can be extended out of and withdrawn into said cylinder (), as a drive and/or as guidance for a first component () for the purpose of moving it in relation to a second component (), in particular as a drive for components () of a lifting system (), the piston () is coupled for force transfer purposes to a component () associated with it (first or second component), and the cylinder () is mounted on a cylinder bearing () of the respective other component () associated with the cylinder () and is coupled to said component () for force transfer purposes. According to the invention, the cylinder () is in bearing engagement with the cylinder bearing () such that it can be moved in relation to the cylinder bearing ().
