Default Cheap 10 ton porta power question.

Does anyone know the approximate bore diameter of the 10 ton porta power ram? I have a job coming that will be pushing the limits of our 7.5 ton gantry crane and want to figure out how much things weigh before just going for it. I would take it to the truck scale in town but everyone around here has switched to the above ground scales and a combine is just too wide to fit. I'm thinking that I can put a pressure gauge on a tee and by reading the pressure I can figure the weight.

What you see starting at 3:30 is what I will have to undo, if the insurance company decides to fix it.

I would look at brackets and jacks, and lift the top from the bottom that way. Are you replacing the top piece, or the bottom?

If you have a Enerpac 10 ton cylinder, the square inches of piston area is 3.14"
Just so happens to be the same size cylinder I used to use on some manufacturing equipment I used to make. Ken

You have the force, and if the pressure is known, you can back calculate the piston size used to create it.

The lower frame is what I'll be replacing. I don't have enough crane to pick the top half off so I plan on building stands for the front and lifting the back with the crane. Then I will roll the bottom frame out on the wheels. The frame is taller in the back than the front is so the bottom has to go out the back. The big question is do I need to pull the power pack off to be able to lift it or can I save 4 days labor and leave it in place.

Brackets and jacks will be in the way. I can do that on one end but not the other.
