The UltraLift Powered Landing Gear Tool is designed to eliminate the hand-cranking typically required for raising and lowering of semi-trailer landing gear. Once one's trailer is retrofitted with UltraLift's bolt-on adaptor (with no permanent modifications needed to the trailer), the UltraLift is inserted into the adapter, and the trigger is used to raise or lower the landing gear. There is no need to hook onto power from any other source. A manual crank incorporated into the adapter serves as a back-up. One tool can be used for any other trailers fitted with the adaptors.
