摘要:
A fluid power interlock system and method for providing same including a circuit having a first valve shiftable between a first and second state having an input and a pair of selectively operable first outputs. One of the first outputs is operatively connectable to a first actuator and the other of the first outputs is operatively connected to a second valve shiftable between a first and second state. The second valve has a pair of selectively operable outputs, one of the second valve outputs is operatively connectable to a second actuator, and the other of the second valve outputs is operatively connected to the first valve and provides a pilot signal thereto for permitting the first valve to shift from a first state to a second state. Shifting state of either of the first and second valves interrupts the pilot signal thereby preventing the non actuated valve from being actuated and shifting state. The system may also include a manifold, wherein the first and second valves are secured to the manifold.
