Trailer "Flip-Up Side" LIFT....Ideas ??

The motor in a power lift chair is rated for 24 volts but it has a fair amount of power at 12v. If you find a lift chair being tossed grab the lift motor and drive rail assembly, the hand set and the connection to the power supply. They actually use a 9v battery for a backupin case the power goes out, it will lift the chair once or twice if someone is in it so 12v should work for you.
