I took a chance today, and bought a brand new right angle drive assembly, with an acme screw about 36" long sticking out of the top of it, with a heavy L bracket on the nut so it travels up and down on the acme screw. Screw is about 1" in diamter, and the entire unit was designed to be bolted down, right angle drive at the bottom, with a place for a top support bearing on the end of the acme screw.
The right angle drive, which has (2) 3/8" keyed drive shafts, is a Joyce/Dayton RWJT62-25 and is rated at 2 tons.
I believe this is the unit...
This was in reference to someone who needed to pick somone up some 30 odd inches.
This is the proper unit to do it with

"The importance of morality is that people behave themselves even if nobody's watching. There are not enough cops and laws to replace personal morality as a means to produce a civilized society. Indeed, the police and criminal justice system are the last desperate line of defense for a civilized society. Unfortunately, too many of us see police, laws and the criminal justice system as society's first line of defense." --Walter Williams
