Abstract:
A method and apparatus for selectively activating a gravity down mode of a hydraulic system during operation of a lift gate. An electronic control circuit is added to hydraulic control circuitry and is configured to selectively interrupt the power down mode or gravity down mode of operation of the hydraulic system based on either a manual input (override) or a sensed condition and switch to the other mode of operation.
