FIELD: transport engineering; vehicles with hydraulic steering gears. SUBSTANCE: discharge hole of positive displacement hydraulic steering gear is connected to pressure hydraulic line of hydraulic system working circuit hydraulic distributor through check valve to input of which pressure valve is connected whose hydraulic control line is connected with output of check valve. Deliveries of two pumps of working equipment and steering gear are combined to drive more energy consuming working circuit and, thanks to it, installed power of hydraulic system pumps can be reduced and in case of failure of one pumps, serviceability of working circuit is preserved. EFFECT: enhanced efficiency and functional reliability of fork-lift truck. 4 cl, 3 dwg
