Described is an electric telehandler (1) comprising: one or more traction apparatuses (3, 51, 6) equipped with a drive wheel (3); movement means comprising a plurality of hydraulic actuators, a hydraulic distributor (2) to actuate the actuators and a pump (21) for supplying the distributor (2); and an electric motor (4, 41, 42, 43, 44, 45, 46, 47, 48, 49) connected directly to the traction apparatus and/or to the pump (21) of the movement means.

An electrical method for centering telehandler rear wheels preferably includes an electronic control module (ECM), a rear steering cylinder, a pair of rear centering valves, a front steering cylinder, a steer mode valve, at least one steering position sensor, a steering control unit and a mode selection switch. The front and rear steering cylinders are connected to the steer mode valve. The steering control unit directs hydraulic fluid from a hydraulic pump to flow into the front and rear steering cylinders to turn the wheels. A 2W steering mode requires that the rear wheels be straight before going from a 4W steering mode into the 2W steering mode. The ECM monitors a position of the rear wheels through the at least one steering position sensor. If the wheels are not straight, the ECM will open a centering valve to straighten the rear wheels, before going into the 2W steering mode.
