PROBLEM TO BE SOLVED: To provide a vehicle for high lift work avoiding any runaway on a slope and enhancing the safety of the work even while wheels on one side of the vehicle are floated.SOLUTION: The working vehicle includes first and second traveling motors M1, M2 rotationally driven with oil supply from a hydraulic pump P1 to drive driving wheels. The working vehicle further includes: a first oil passage L1 connected to one port of the hydraulic pump P1; a No.1-1 branch oil passage and a No.1-2 branch oil passage branching from the first oil passage and connected to one port of the first and second hydraulic motors respectively; a second oil passage L2 connected to the other port of the hydraulic pump P1; a No.2-1 branch oil passage and a No.2-2 branch oil passage branching from the second oil passage L2 and connected to the other port of the first and second hydraulic motors M1, M2 respectively; and first and second traveling control valves provided in the No.1-1 and No.1-2 branch oil passages respectively, allowing the flow of oil in the direction for driving the first and second hydraulic motor, and restricting the flow of oil in the opposite direction based on an operation of a travelling operation means. |
