An industrial truck comprises a vehicle body, a lifting frame, at least one load wheel, at least one further wheel, at least one actuator, at least one detection unit configured to detect a current operating parameter of the industrial truck, and a control unit. The control unit is configured to define a target state of the industrial truck, to receive data from the detection unit to determine an actual state of the industrial truck based on the detected operating parameters of the industrial truck, to calculate the effects of possible adjustments of the relative position of the load wheel with respect to the vehicle body on the actual state of the industrial truck, and to instruct the at least one actuator to adjust the relative position of the load wheel with respect to the vehicle body to approximate the actual state of the industrial truck to the target state.

The present invention relates to a wheel arm forklift truck (1), preferably as an automated guided vehicle, comprising a front end (10c) having at least, preferably exactly, two steerable drive rollers (11a, 11b); comprising at least one first wheel arm (10a) which extends in a straight line away from the front end (10c) and is fixedly connected to the front end (10c), wherein the first wheel arm (10a) has at least, preferably exactly, one first roller (12a); and comprising at least one first fork arm (15a) which is located above the first wheel arm (10a) in the vertical direction (Z) and is designed to be raised and lowered in the vertical direction (Z). The wheel arm forklift truck (1) is characterized in that the first roller (12a) of the first wheel arm (10a) is steerable through at least 90°.

The present disclosure relates to the technical field of mechanical equipment for aerial works, in particular to a small scissor aerial work platform and a traveling chassis thereof. The traveling chassis includes a base and oppositely-arranged left and right steering wheel assemblies. The base is of a concave structure, a scissor-stored groove with an upward opening is formed in the base, a left wheel set accommodating groove and a right wheel set accommodating groove which are used for accommodating the steering wheel assemblies and provided with downward openings are further formed in a front end of the base, and a lower portion of the scissor-stored groove is located between the left wheel set accommodating groove and the right wheel set accommodating groove.

A device for the deaeration of a hydraulic fluid of a hydraulic system has at least one hydraulic motor arrangement and a hydraulic fluid storage which is hydraulically coupled with this hydraulic motor arrangement. A suction device for sucking out the hydraulic fluid is associated with the at least one hydraulic motor arrangement such that the suction device guides hydraulic fluid out of the hydraulic motor arrangement into the hydraulic fluid storage by means of vacuum pressure (Δp). The suction device is constructed as a jet pump and is integrated in the return line between the hydraulic motor arrangement and hydraulic fluid storage.

A forklift includes: an armrest that is provided at a driver's seat of a vehicle and is moved between a non-operation position and an operation position by a movable mechanism; a steering member that outputs an operation signal in response to a steering operation; a steering device that changes a steering angle of steering wheels of the vehicle; a control unit that changes the steering angle according to the operation signal; and an armrest detection unit that detects whether the armrest is at the non-operation position or at the operation position in which when the armrest detection unit detects that the armrest is at the non-operation position, the control unit controls the steering device or the steering member such that the steering device does not change the steering angle even if the steering member is operated.

An object responsive control system for a work machine having a boom, an attachment pivotally coupled to the boom, an object sensor adapted for sensing the presence of an undesirable object located in a travel path of the work machine and delivering an object signal upon sensing the undesirable object. A controller adapted for receiving a boom position signal, an attachment position signal, and calculating an elevational position based on the boom position signal. The system activating an object response upon calculating an attachment elevation position above a predetermined threshold and receiving an object signal.

A materials handling vehicle comprises an operator compartment, a compartment tower, a multi-field scanning tool, and mechanisms that facilitate movement along a travel plane in a warehouse. The tool establishes a scan field, and, within scan field bounds, an occupancy detection field and an obstacle detection field. Tool scanning hardware is configured to generate the scan field from a point of origin that is elevated relative to the operator compartment and to expand the scan field such that it intersects the operator compartment and extends laterally beyond lateral edges of the operator compartment such that the occupancy detection field falls within the operator compartment, the obstacle detection field falls outside of the operator compartment, and the multi-field scanning tool is configured to indicate the presence of an occupant in the occupancy detection field and obstacles in the obstacle detection field.

A multidirectional transport vehicle includes a longitudinal axis which defines a longitudinal direction, a transverse axis which defines a transverse direction, a steering system, a driving direction switch, and a driving direction adjustment element. The steering system comprises at least three independently steerable wheels and a steering target value transmitter which steers the wheels. Each wheel has a wheel axle. A steering pole, on which each wheel axle is aligned when cornering, is moved along a steering pole axis by actuating the steering target value transmitter. The driving direction switch includes a limited number of separate switch positions, wherein exactly one switch position preselects exactly one respective rotational position of the steering pole axis relative to the multidirectional transport vehicle and preselects one of two driving directions facilitated thereby. The driving direction adjustment element changes a preselectable rotational position of the steering pole axis.

A vehicle includes a vehicle controller communicating over a first communication system with actuators for changing the state of vehicle systems. A signal module communicates with the vehicle controller via the first communication system. One or more signal sources communicate with the signal module via a second communication system, and transmit signals to the signal module. Based on one or more signals and one or more user inputs, the signal module generates and transmits control signals to the vehicle controller. The vehicle controller actuates the actuator based on the control signal.
