The valve assembly is configured to (a) direct a first portion of the flow of pressurized fluid to the drive pump and (b) selectively direct a second portion of the flow of pressurized fluid to the hydraulic actuator.

A working machine has a body, a ground-engaging propulsion structure supporting the body, an inclinable working arm pivotally connected to the body mounting a working implement at a distal end thereof, a drive arrangement configured to provide motive power, and a control system configured to determine a center of gravity of the working machine. The control system is configured to control or restrict a speed of movement of the working machine in response to the determined center of gravity.

Mainframes for a self-propelled machine are disclosed. The mainframe includes first and second pockets that extend from the front end to the rear end of the mainframe. A hydraulic reservoir housing extends from the first side to the second side of the mainframe. The hydraulic reservoir housing is disposed between the front end of the mainframe and first and second drive openings.

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.

An industrial vehicle work guide system is disclosed. An industrial vehicle work guide system according to an embodiment of the present invention includes: a memory configured to store engine used data, a driving time, a fuel consumption amount, and reference fuel efficiency; a display module configured to output a guide message; and an analysis module configured to calculate actual fuel efficiency by using the engine used data, the driving time, and the fuel consumption amount, compare the actual fuel efficiency with the reference fuel efficiency, and control the display module so that the display module outputs a guide message when the actual fuel efficiency is lower than the reference fuel efficiency.

A housing for a hydraulic actuator unit of a pallet truck is disclosed. The housing includes a lift motor mount for mounting a lift motor to the housing and a pump mount for mounting a hydraulic pump to the housing, and couples the pump to the lift motor when each are mounted. The housing includes a hydraulic cylinder with a cylinder rod, which is positioned based on the fluid level in the hydraulic cylinder; a reservoir to store fluid for actuation of the cylinder rod; and one or more fluid galleries that extend, internal to the housing, among the fluid reservoir, the pump mount, and the hydraulic cylinder. A traction motor mount mounts the traction motor, which is coupled to a steering unit of the pallet truck and controls actuation of a traction wheel of the pallet truck when the traction motor is mounted to the traction motor mount.

Controlling a maximum vehicle speed for an industrial vehicle includes determining, by a processor of the industrial vehicle, a torque applied to the traction wheel of the industrial vehicle; converting the torque to an equivalent force value; and determining an acceleration of the industrial vehicle while the torque is applied to the traction wheel. Additional steps include calculating a load being moved by the industrial vehicle, based at least in part on the acceleration and the equivalent force value; and controlling the maximum speed of the industrial vehicle based on the calculated load being moved by the industrial vehicle.

An industrial vehicle includes a body, an axle pivotally supported by the body, a lateral acceleration sensor determining lateral acceleration applied to the body when the industrial vehicle is turned, an actuator temporally restricting pivoting of the axle while the industrial vehicle is being turned, a vehicle speed limiter limiting traveling speed of the industrial vehicle when the industrial vehicle is turned, and a controller driving the actuator based on the lateral acceleration determined by the lateral acceleration sensor to temporally restrict pivoting of the axle and to limit traveling speed of the industrial vehicle based on the lateral acceleration. In the controller a first lateral acceleration threshold value which is used in judging whether traveling speed of the industrial vehicle should be limited is set larger than a second lateral acceleration threshold value which is used in judging whether pivoting of the axle should be temporally restricted.
