ABSTRACT:
A hydraulically driven industrial machine having a variable displacement type hydraulic pump adapted to take in and pressurized working oil from an working oil tank, a hydraulic actuator to be driven by pressurized working oil delivered from the hydraulic pump through a control valve to perform a predetermined job, a variable return oil cooling means capable of cooling return oil from the hydraulic actuator at a varying cooling rate, an operational load detection means adapted to detect an operational load factor of the hydraulic actuator, and a control means adapted to vary the return oil cooling rate on the basis of an operational load factor detected by the operational load detection means.
