ABSTRACT:
An interlocking change-over valve system for use in a hydraulically controlled mechanism includes a plurality of hydraulic actuators and at least one valve corresponding to each actuator for controlling the hydraulic pressure supplied to each actuator. A hydraulic cylinder communicates with each valve for opening and closing the valve. A control device remotely activates the hydraulic cylinder to selectively supply hydraulic pressure to some of the hydraulic actuators.
