Description
Equipment that needs to be raised and lowered is typically powered by hydraulics or a screw type crank. Workers with hand, arm, shoulder, and strength disabilities can find it tiring or difficult to crank on a handle to power a winch without hydraulics. Angle drills can be used for powering winches.
A farmer who is hooking up a trailer with a conventional trailer jack will find it much easier to have use an angle drill with an adapter to raise and lower the jack.
