A handle and tiller head plug-in module for a material handling vehicle. The handle having an elongated tiller having an upper portion including at least one steering handgrip member and an upward extending wall surrounding electrical contacts associated with operator control functions. The tiller head plug-in module includes a housing having a downward extending wall surrounding electrical contacts, with the housing supporting a plurality of operator control interface elements, including at least one lift control element, and at least drive control element. The tiller head plug-in module is configured to be removably electrically connected to the handle when the upward extending wall surrounding the electrical contacts of the upper portion of the tiller is plugged into and received by the downward extending wall surrounding the electrical contacts of the housing.

A mobility device lift system including an electric pallet jack having a handle, a pallet, a ramp, a vertical lifting mechanism, and a wheel assembly. The pallet is sized and functionally configured to support a mobility device thereon. The pallet is affixed to the vertical lifting mechanism, such that the pallet is able to move up and down vertically via hydraulics of the vertical lifting mechanism. The electric pallet jack is configured for transporting the mobility device from a loading bridge to a belt loader. The ramp of the device provides a connector between the loading bridge and the belt loader.

Vehicles, systems and methods for providing articulating two section vehicles with tracks, and a front body attached superstructure with telescopic forklift, for use on all terrain condition applications. The vehicle can include front and rear track assemblies that can tilt up and down while traveling over different ground surfaces. Each of the track assemblies can have rotatable articulating/oscillating track wheels which can traverse different contoured surfaces. The right and left tracks on both the front and rear track assemblies can separately extend outward and inward from underneath the vehicles to add stability to the vehicles. The cab can be raised and lowered to add greater visibility for the operator. Hydraulics can be used for raising and lowering the extendable boom and operator cab, as well as controlling the body articulating hinge, the articulating tracks and the tilting controls for the front track assembly.

A method for operating an industrial truck having three wheels. During longitudinal travel, two steerable wheels run in succession in a first lane, and a third wheel runs in a second lane. The third wheel initially runs on an inside during a turning in while cornering until the industrial truck, during a further turning in, transitions into a revolving motion. The method includes reducing a drive power as of a specific steering angle during the turning in prior to the revolving motion, and disengaging or reversing a direction of a drive rotation of the third wheel after a delay time which begins with the reducing of the drive power, or, continuously reducing the drive power from the specific steering angle during the further turning in, and disengaging or reversing the direction of rotation of the third wheel when transitioning into the revolving motion.

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 steering system includes a first wheel and a second wheel spaced apart from the first wheel, a first tie rod, a second tie rod, and an electrical actuator. The first wheel is rotatably coupled to a first knuckle, and the first knuckle is pivotable about a first suspension post. The second wheel is rotatably coupled to a second knuckle, and the second knuckle is pivotable about a second suspension post spaced apart from the first suspension post. The first tie rod is coupled to the first knuckle and to a mechanical linkage. The second tie rod is coupled to the second knuckle and the mechanical linkage. The electrical actuator is coupled to the mechanical linkage so that movement of the electrical actuator translates the mechanical linkage axially, which adjusts the orientation of the wheels relative to the suspension posts.

A material handling vehicle. The material handling vehicle including a vehicle body, an operator compartment, and a mast. The mast has a mounting platform, a first support member coupled to the mounting platform, a second support member coupled to the mounting platform, and a detection system coupled to the mast. The mast is coupled to the vehicle body at a frontward location relative to the operator compartment. The position of the mast on the vehicle body prevents the mast from impeding a field of view of an operator positioned in the operator compartment.

A height adjustment module includes a mounting part extending on a plane; a plurality of support arms disposed around the mounting part on the plane on which the mounting part has been extended, and coupled to the mounting part to be rotatable upward or downward; a plurality of travelling parts each being coupled to a first end portion of the support arm, respectively, and including a wheel contacting the ground, respectively; a lift extending over the plane, and connected to second end portions of the plurality of support arms so that vertical movement is interlocked with each other; and a support link coupled to the mounting part to be vertically slidable, and coupled to the lift to be vertically fixed to move the mounting part relative to the lift as the support link is slid in the mounting part.

A work vehicle includes a hydraulic actuator, a control valve, a pressure sensing unit, a force imparting component, and a controller. The hydraulic actuator varies a steering angle. The control valve controls flow of fluid supplied to the hydraulic actuator. The operation member is configured to be operated by an operator and to control the control valve when varying the steering angle. The pressure sensing unit senses a pressure produced by the hydraulic actuator. The force imparting component imparts an assisting force or a counterforce to operation of the operation member. The controller controls the force imparting component so as to generate resistance to operation of the operation member based on a pressure value sensed by the pressure sensing unit.
