The invention concerns a hydraulic stabilizing system (10, 110, 210) comprising: a plurality of hydraulic stabilizing jacks (12, 112, 212), each of said jacks having an actuator (20, 120, 220) comprising: an actuator cylinder (28, 128, 228); an actuator piston (30, 130, 230) slidingly engaged with said actuator cylinder, said actuator piston cooperating with said actuator cylinder to define an actuator extend chamber (38, 138, 238) and an actuator retract chamber (40, 140, 240); an actuator piston rod (32, 132, 232) connected to said actuator piston and selectively extendable from and retractable into said jack cylinder; and one of a pilot-operated check valve (42) and a pilot-operated directional valve (176, 276) having a first flow port connected to one of said actuator retract chamber and said actuator extend chamber in fluid communication therewith; a fluid transfer pump (44, 144, 244); and a first hydraulic line (70, 170, 270) connecting an output of said pump with one of said actuator extend chamber and said actuator retract chamber of said at least one of said actuators and with a second flow port of said one of a pilot-operated check valve and a pilot-operated directional valve of said at least one of said actuators.
