Abstract
An apparatus for controlling a first fluid cylinder and a second fluid cylinder includes an operational pressure source and a fluid control circuit. The fluid control circuit includes a pilot valve assembly having a first valve position and a second valve position. Moreover, the fluid control circuit (1) delivers pressure from the operational pressure source to the first fluid cylinder when the pilot valve assembly is positioned in the first valve position, (2) isolates the second fluid cylinder from the operational pressure source when the pilot valve assembly is positioned in the first valve position, (3) delivers pressure from the operational pressure source to the second fluid cylinder when the pilot valve assembly is positioned in the second valve position, and (4) isolates the first fluid cylinder from the operational pressure source when the pilot valve assembly is positioned in the second valve position. A method for controlling a first fluid cylinder and a second fluid cylinder is also disclosed.
