An industrial truck includes at least two steerable wheels, each of which is configured to be steerable independently of one another, and a steering angle control. Each of the at least two steerable wheels has assigned thereto one steering drive unit which comprises a rotary steering motor, and one steering shaft. Each one of the at least two steerable wheels is connected to the rotary steering motor of the steering drive unit via the steering shaft which is assigned thereto. The steering angle control controls each rotary steering motor. The steering angle control has at least one rotational angle detection device which detects a current rotational angle position of each steering shaft. The at least one rotational angle detection device is designed as a part of each steering drive unit.

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.

The safety device comprises a vehicle body inclination angle detector to detect an inclination angle of the vehicle body. In a vehicle body attitude in which the inclination angle of the vehicle body detected by the vehicle body inclination angle detector is less than a predetermined inclination angle, while any travel operation by the travel operation device is not performed, when a steering operation by the steering operation device is performed, the travel controller performs control to release braking the front wheels and the rear wheels by the brake device and to make the steering device turn the front wheels and the rear wheels in accordance with the steering operation.

A vehicle including a control valve to lift and lower a boom. The vehicle further includes a control circuit to control a speed of the boom lowering via a pressure compensator that balances a first pressure signal downstream of a control valve during the boom lowering and a second pressure signal from a hydraulic user interface so that, upon increasing of the first pressure signal during the boom lowering, the control valve progressively closes.

A method of controlling a hydraulic control system of a material handling vehicle is provided. The method includes detecting an elevated height of a fork assembly, determining if the elevated height is above a first predetermined height threshold, and actuating a first low pressure control valve from a control valve closed position to a control valve open position to provide fluid communication from a supply passage to the first low pressure relief valve when the elevated height is above a first predetermined height threshold.
