    Exactly what Fish On said in response to the original question.

    I am sure a company like Pacific will make you anything, but costly no doubt. If you really have a good steady use for it, but can't fit an 8ft wide brake...buy one used and cut it down/rebuild to 4ft? That or build completely from scratch yourself would be the only "budget friendly" options imo, and probably what I would do before paying pacific or another company to build me one. Though figuring a way to accommodate a 6-8ft brake would probably be more economical and more useful in the end for most peoples situations.

    Hi M.Moore,
    KAAST Machine Tools has a manual hydraulic pressbrake with a small footprint and high tonnage. They call is the HPA-P. I think they start at 3'x100 tons and go up to 200 tons. The one I have is 60" x 150 t and it will bend 1/2" plate like buttah!

    I wish I had the space and that kind of money. (Dream big and one day it may come true)

    In the mean time I got a 10" cylinder give to me out of a concrete breaking machine and a Ram Pac 10,000 psi pump and I am going to be building my own little press brake. Should be good for 200 ton but will only have a 3.5 " stroke.

    I doubt if your 10" cylinder is good for more than 4,000 psi, might be 6,000. But I have never seen 10,000 psi on equipment. You will want to check out the maximum pressure on your cylinder before using.

    Goldsmith,
    Those do look good! Your 5’er just has the one main cylinder and two guide columns?
    How much?

    It is rated for 10,000 but will limit it to 8,000 due to line rating. Thanks for the heads up though.

    Am I the only one that sees issue with the 3.5" stroke? Even if you make TDC mere microns above the pinch point (which is going to be severely limiting on shapes that you can actually get out of the machine after bending), I don't think that's enough stroke to fully bend something in an 8 or 10" die (assuming we're really talking about bending 3/4 and thicker plate in this).

    Yup, a simple trig layout will reveal all....

    Do you know what its out of or have a picture? Most of those are only rated for 2.5" of stroke, then they're gravity or external spring return. If it'll work for you, they're simple but durable cylinders, normally they're plumbed to SPX powerteam pumps and use ATF as the hydraulic fluid. If you know someone scrapping one of them, I'd be interested in the valving if its still available.

    It's a KAAST, not Kasto!
    The 60" x 150 t cost me $26,000 but they also had a 40"x100 t I was considering for $18,500.
    Can't figure out why my photos don't post!

    If you need a real narrow high tonnage press brake maybe don't call it a press brake anymore? I have a 300 ton Bliss straight side stamping press with 9 inches of stroke that would hold 24" of punch and die if a guy needed to use it for that I guess. I paid a lot more to crane it's 21 ton ass into the shop than I gave for the machine. Paid about 10% of scrap value for it.

    Before I found the Bliss, I was collecting parts to build a 200 ton hydraulic forming press. I had two 10.5" cylinders from a 200 ton die casting press I was going to use. They were built like brick shithouses, but still only rated for 3000 PSI. Those cylinders weighed 3400 pounds EACH. I don't remember the stroke, but it was around 12 inches.

    I have found it's much more efficient to just buy what you need than build it when it comes to big stuff like this. A few months back there was a 500 ton hydraulic straight side press up for sale near me. It was pretty much if you were willing to pay for craning and hauling something 25 feet tall and 80,000 pounds you could just have it.

    I remember just moving those two die cast machine cylinders around. My 4000 lb forklift could only lift one. I remember hauling them in the bed of my 93 dodge 3/4 ton. Guy loaded them with an excavator and I had to have him take one out and I made a second trip an hour each way. What a waste of time.

    And it’s already Yoder blue!

    They’re actually pretty good to deal with, just wish they didn’t paint everything blue?

    That is one helluva big chunk of iron, wonder what it weighs?

    Interesting the tonnage indicator red lines at 150 ton, but the scale goes to 300 ton.

    I was thinking the same thing. I suppose that's the mindset most folks have with mechanicals- "It does 1/4 good, so it'll do 1/2" OK."

    I've been fixing up an old Verson I have and the thing is just massive for it's rated tonnage compared to the Hydro-mechanical Diacros of the same tonnage I'm used to. This little 25ish ton Verson is the same beef as a 100 ton Diacro. I suspect it was just assumed people would overload a mechanical and the builders made it to take that abuse.
