Abstract: A control system includes a valve that alternately energizes one end of a main hydraulic cylinder to raise a gas gun, energizes the other end of the cylinder to raise a gas gun truck and drains both ends to permit gun or truck free fall. A control cylinder coupled in parallel with the main cylinder prevents actuation of the valve to raise the gun when the truck is raised, and vice versa. Truck free fall is initiated by a kickoff cylinder which operates on the main cylinder. The rate of both gun and truck free fall is controlled by orifices.
