A running control circuit for a hydraulically driven running device comprising a hydraulic pump, parallel left- and right-hand directional control valves provided along a discharge path of the hydraulic pump, sets of first left- and right-hand circuits and second left- and right-hand circuits formed by connecting output sides of the left- and right-hand directional control valves to left- and right-hand running hydraulic motors, respectively, and pressure compensating valves each provided along the first and second circuits for controlling an opening area between an inlet port and an outlet port thereof by virtue of the difference in pressure between its own loading pressure and the highest of the loading pressures of the left- and right-hand running hydraulic motors for compensation of pressure, wherein the pressure compensating valves are constructed to function such that they establish communications between the first left- and right-hand circuits and between the second left- and right-hand circuits via a communication path, respectively, when compensating for hydraulic oil, while they cut off communications between the first left- and right-hand circuits and between the second left- and right-hand circuits when a communication between the inlet and outlet ports is cut off or substantially cut off.
