That's just the basic power unit, it's up to YOU to figure out how to couple the thing to what you want to bend(straighten) and with what. Probably there's a community college course on auto body repair that covers how to use it fully.

I haven't used that one but standard ones depend on having lots of tie down spots in the floor. A friend poured his garage floor with strategic loops of rebar sticking up around the edges. A regular shop might have steel T bar slots cast in the floor.
This unit looks like it has two pulleys suitable for chain. To use, you set the vehicle up on some heavy duty special purpose jack stands and anchor with chain. The pull arm is set up to get the proper pull direction angle and then held in place with chains to your floor system. The cahin is attached to the the vehicle, run through the upper chain pulley, down to the lower chain pulley on the triangle plate attached to the cylinder, and back up to the secondary anchor or to the notch in the triangle block.
The low buck version of these are nothing more than some stands with a suitable post and link positions that can be chained in place. Hook up a ratcheting chain hoist to get the pull you need.
The pros at this are really fun to watch. The car uncrumples like some animati>
I've never seen one, but the downloaded manual shows a bellcrank in the base that apparently moves a pulley downward as the ram extends. Another pulley higher up changes the vertical pull to horizontal? I presume it's easier and faster to set up than loose chains and a pull- back ram or cable pullers although you still need a solid anchor and the pump from a Porta-Power kit.

Ok. I got it now. I have always used a piece of I-beam, some blocks, hooks and/or chain, and a hydraulic jack. Since I do not plan to put anchors in the floor of my shop for that sort of thing I'll just stick with my I-beam. I was hoping it was some really clever miracle device that I just didn't understand.
I use two big trees and a cable puller.
You guys sure must run into a lot of stuff. d8-)
I've only hit things three times in 46 years of driving, plus one time on a race track, and I made damned sure my vehicle was destroyed beyond repair each time. It sure makes life simpler.
Oh, and make sure you're wearing your seat belt...

I run into a lot of welding distortion, and the local kids think I'm a MacGyver who can fix anything.
