Hey guys, I saw all the discussion about using twin rams. I know OTC routinely used twin rams in their line of cylinders, and if I'm not mistaking one of the applications they used to use them in was their pin press, until they quit making them that is. I believe they used either a 50 or 75 ton twin ram for power. I have a 30 ton Twin Ram on my truck now that has a single oil connection with the bases connected together and a crossbar on the rods with a hole in it. It's designed to do basically the same thing Enerpacs Hollo-Rams do to be able to push or pull depending on how you set it up..... As long as you both cylinders are connected together(IE one oil supply from the pump) they will always act with equal force, just like a set of lift cylinders on a loader do. Roy, good luck on your press. We made us a "portable" one several years ago with 75 ton single ram to break tracks with and it has been a lifesaver.
