Abstract
A device and method used to raise or lower the landing gear of a semi-trailer. The device is coupled to the landing gear of the semi-trailer and actuates the landing gear according to user selection. The user may select to actuate the landing gear through a motorized gear assembly within the device, by optionally attaching a handle to the landing gear via the device, or by engaging a separate motorized hand tool to the landing gear via the device. To use the handle or the motorized hand tool, the user actuates a shift lever disposed on the device which disengages the related mechanical means for actuating the landing gear. The flexibility for actuating the landing gear allows a user to raise or lower the landing gear according to the surrounding circumstances or in case one of the means for actuating breaks or fails.
