Abstract
A locking mechanism for a base plate of a vibratory compactor includes a locking actuator configured to alternately lock and unlock the base plate relative to the vibratory compactor, and a hydraulic control circuit in fluid communication with a source of pressurized hydraulic fluid and the locking actuator. The hydraulic control circuit includes a hydraulic pilot-pressure-actuated, 2-position spool valve, wherein the spool valve is configured to move to a first position when pressurized hydraulic fluid from the source is supplied to the spool valve in a first direction, and move to a second position when the pressurized hydraulic fluid from the source is supplied to the spool valve in a second direction. In the first position of the spool valve the pressurized hydraulic fluid moves the locking actuator to a locked position, and after the locking actuator is in the locked position, the pressurized hydraulic fluid operates a hydraulic motor configured to power the vibratory compactor. In the second position of the spool valve the pressurized hydraulic fluid moves the locking actuator to an unlocked position.
