MAGNUM LIFT allows you to easily convert your heavy duty 2 speed Binkley - Holland, Bulldog or other similar gooseneck trailer jack to electric power operation.
Designed to be mounted on the 1-1/2" input shaft hub (collar) of gooseneck horse/stock trailers and fifth wheel or gooseneck race/cargo trailer jacks.
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 Bracket kit shown as an option just above the Add To Cart button.
Runs from trailer's existing 12 Volt DC power source.
Comes as a complete kit with switch box, wiring harness, electrical connectors, manual override and mounting bracket.
If space is an issue this kit can be mounted on the opposite side of jack from gear box (see last 2 images). Some welding is required for this mounting method.
Motor is a single speed unit designed to be used on LOW speed side of gear box only.
Factory rated lifting capacity at hitch appx.* 6,500 lb.
Lifting speed is 7" per minute appx.
The Magnum Electric is 9-1/2" wide, and installs in standard position with basic hand tools. 2-Year factory warranty.
Jack shown for illustration purpose ONLY. Available and sold separately.
*Can vary depending on condition of jack, trailer geometry, parking position etc.
