I bought a foot-pumped hydraulic cart.

It worked OK but I wanted the platform to lift without any effort on my part.
The existing cylinder and pump got replaced by a hardware store bottle jack
driven by a windshield wiper motor from a junkyard.

The wiper motor cost only twenty bucks, so I put a lot more power into it than
is advisable.

I welded a washer to the pressure release valve of the bottle jack and control
it via a lawnmower throttle mounted to the pushbar.

The table is powered with a rechargeable 24V battery I had spare.

This table will lift 260 lbs from 11.25" to 31.5" in about a minute and a half.
