Abstract
In a hydraulic driving system, a plurality of loading-line driving devices adjust a flow rate of an operating liquid flowing from a loading-line pump to a loading-line actuator, and a steering-line driving device adjusts a flow rate of the operating liquid flowing from the steering-line pump to the steering actuator. When one of a plurality of loading-line actuators is driving, a switching valve device connects a loading-side passage and a steering-side passage. When any of the plurality of loading-line actuators is not driving, the switching valve device disconnects the loading-side passage and the steering-side passage.
