Magnum Lift LEGB-2 Electric 12V power conversion kit, for 2 Speed Gooseneck Trailer Jacks

The MAGNUM LIFT LEGB-2 allows you to easily convert your heavy duty 2 speed Binkley - Holland, Bulldog or other similar gooseneck horse or car trailer jack to electric power operation. Please note, this kit is not intended for use on semi or heavy equipment type trailers. Maximum weight lifting capacity at the jack leg/s is appx. 7,000 lb.   Designed to be mounted on the 1-1/2" input shaft support hub (collar) of gooseneck horse/stock trailers and fifth wheel or gooseneck race/cargo trailer jacks. See the jack image with the support hub circled for clarification. Holland/Binkley brand jacks manufactured after September 2010 no longer have the support hub welded to the gear box. If the hub is not present on your jack you will need to add the 1-1/2" Support Hub Adapter Bracket kit.   Electric motor coupler fits jacks with 1" diameter crank shafts only. Runs from trailer's existing 12 Volt DC battery power source. A 12 volt automotive style battery MUST be available to sup
