摘要： A working machine includes a hydraulic control apparatus. In a straight travel valve of the hydraulic control apparatus, a communication path and a control valve that opens and closes the communication path are provided. During a combined operation of traveling operation and working operation, a working pressure and a traveling pressure are taken in as pilot pressures on either side. During a small traveling operation in which the traveling operation amount is small, the communication path is unconditionally closed. During a large traveling operation in which the traveling operation amount is large, if the working pressure is higher than the traveling pressure, the communication path is open, and if the working pressure is lower than the traveling pressure, the communication path is closed.

摘要： A hydraulic control system for a working machine according to the present invention includes a regulator control valve for controlling an operation of a pump regulator and a controller for sending a control signal for changing a discharge quantity of the pump to the regulator control valve in accordance with an operation amount of an operating means. On the basis of the control signal, a secondary pressure in the regulator control valve is fed to the pump regulator. This system further includes a fail-safe valve disposed in a control line joining the pump regulator and the regulator control valve. The fail-safe valve has an ordinary position for sending the secondary pressure to the pump regulator and a fail-safe position for sending an oil pressure from a path other than the regulator control valve to the pump regulator in such a manner that a predetermined discharge amount is ensured. The fail-safe valve is configured so as to switch from the ordinary position to the fail-safe position in accordance with a failure signal indicative of failure in the regulator control valve. According to this, while adopting an electronic control system for the pump, it is possible to continue a work even in the failed condition of the system.
