Electric 12V powered conversion kit engineered to mount to the two speed gearbox on heavy duty 2 speed gooseneck trailer jacks used on horse trailers and race car haulers.
Utilize your existing RV or automotive type trailer battery to supply the required 12 Volt power for the heavy duty motor.
This kit was designed for mounting to the welded 1-1/2" diameter support hub installed on most Holland / Binkley model landing leg jacks used on horse and livestock trailers.
If your jack does not have the support collar our adapter hub kit may be required for installation. See details on the HK-2SPD adapter.
A two way (up/down) toggle switch and complete emergency crank handle - extension rod assembly are included with the kit.
The motor - gearbox unit requires a minimum of 10-1/2" on the outboard side for installation and clearance to obstructions.
The crank shaft must measure 4-7/8" from the gearbox to center of the pin hole.
Installation of the kit will lock jack into low speed.
If you are unsure of your jack model or just need more details please call our office at 503-637-5050. We are happy to help you determine if this is the correct kit for your application.
This conversion kit is NOT intended for use on semi trailers.
