通过液压装置来支撑驾驶员在驱动电动工业车辆时施加的转向力。能量由液压泵提供，油压作用在气缸上，减小了驾驶员施加的力。保持了转向阻力，因此可以保持对轴偏移的感觉。

        Supports the steering force to be applied by the driver during steering of motor-driven industrial trucks by means of a hydraulic device. The energy is supplied by a hydraulic pump, the oil pressure acts on a cylinder and reduces the force to be applied by the driver. The steering resistance is retained so that the feeling for the degree of permissible axle excursion is maintained.
