A controller for operative connection to a power assisted transport vehicle that is at least partially directed by a human operator in physical contact with the vehicle, the controller including: a contact surface with a deadman switch, a first sensor and a second sensor each responsive to manual actuation of the contact surface, each sensor having a respective first sensor output signal and a second sensor output signal, and a signal processing means adapted to process the first and second output signals, and control the mode of operation of the controller in accordance with the state of the deadman switch.

A vehicle supported implement for handling separate loads independently, and related methods of use, are presented. The implement is configured to move a load, such as a hay bale, rotating the load radially about an axis, from a first position at a first elevation to a second position at a second elevation. It includes a first frame member and a second frame member pivotally connected to the first frame member at a joint. The axis of rotation intersects the joint normal to the back side of the first frame member and the second frame member rotates radially about the axis of rotation between the first position and the second position. The implement includes an actuator, such as a hydraulic cylinder, connected to the frame members to control the rotation. The implement includes an attachment feature on the back side to secure it to a vehicle.

An apparatus for stacking hay bales comprises a base frame securable to a motorized vehicle, a plurality of tines pivotally connected to the base frame extending to free distal ends, the tines defining locations therebetween spaced to correspond to a bale of hay and a push bar extending parallel to the base frame and movable between a retracted position proximate to the base frame to an extended position along the plurality of tines to push the hay bales from therebetween. In operation, the apparatus is used by passing at least two of a plurality of tines to each side of a hay bale, lifting the hay bale by a platform extending from a base of the plurality of tines and pushing the hay bales off the tines with the push bar.

A working machine has a body and a load handling apparatus coupled to the body. The load handling apparatus is moveable with respect to the body by an electrically driven actuator assembly. A controller is configured to receive a tilt signal representative of a moment of tilt of the working machine and issue a control signal configured to control an electrical drive element of the electrically driven actuator assembly based on the value of the tilt signal relative to a tilt threshold.

Systems and methods for material handling vehicle simulation are provided. In one aspect, a method for material handling vehicle simulation using a material handling vehicle includes connecting a simulation controller to a simulation port, providing an input to a soft switch on a touch screen, upon providing the input to the soft switch on the touch screen, triggering the material handing vehicle to transition from the standard mode to the simulation mode, and projecting a simulated environment onto a simulation display. The simulated environment is configured to simulate operation of the material handling vehicle on the simulation display.

The aerial work platform comprises a chassis (2), optionally a turret (4) mounted pivotably on the chassis, a mechanism (8) for lifting a work platform that is mounted on the chassis or the turret, and a control station (50) arranged on the chassis (2) or the turret (4). The control station comprises: members (52) for controlling the lifting mechanism and optionally the rotation of the turret, a validation member (54), the control members (52) being inhibited in the absence of simultaneous actuation of the validation member, and a handle (70). The mutual arrangement thereof makes it possible to hold the handle (70) and to simultaneously actuate the validation member (54) with a same hand while simultaneously actuating any one of the control members (52) with the other hand.

A forklift includes a fuel cell system. The fuel cell system includes a battery stack and a capacitor and is electrically connected to a vehicle system. The vehicle system includes a control valve that switches supply of hydraulic oil to a power steering cylinder and a cargo-handling cylinder, a cargo-handling pump that supplies hydraulic oil stored in a hydraulic oil tank to the control valve, a cargo-handling motor that drives the cargo-handling pump, and an on-load valve that returns the hydraulic oil from the control valve to the hydraulic oil tank. The fuel cell system operates the fuel cell system to execute a warm-up control. A vehicle ECU continues supplying power from the fuel cell stack to the cargo-handling motor during the execution of the warm-up control.
