What size is my arbor press?

[gjz30075]

Just picked up an arbor press at an estate sale yesterday. There's a Made
in China sticker on it but absolutely no other markings. I'm guessing its
about a 3 ton unit and shown are the dimensions. It's 23 inches tall,
18 inches long and 8 inches wide. Any ideas? And maybe a mfgr?
Thanks!

I picked up the same exact one, at an estate sale and mine only says china. so interested in what other say, I say no more than 1 ton.

Without measuring my 3 ton ratcheting dayton which i think is way taller then 2'. I'd say yours is smaller so 2 tons is my guess.

Good to know. Thanks

Do the math. Simple levers. Lets say you have a 24" handle and a pinion gear with a radius of .75" ( at the pitch dia.) . Apply a 100 lb pull at the end of the handle and you have 24" / .75" x 100lb = 3200lb minus the friction losses.

Plug in your real numbers and you'll have your answer.

Or, if you don't want to disassemble to measure the pinion diameter, measure travel of the ram and travel at the far end of the handle. Handle travel/ram travel x 100lbs is your answer.
Say the handle end travels 10" (keeping it small for easy measuring - straight won't be very different from the arc it actually travels) and the ram travels 1". That's a 10 to 1 advantage, so your 100 lbs applied to the handle end becomes 1,000 lbs at the ram.

You could always look up presses on HF or northern and see what measurements match their press.

this. just google the cheap imports and fine one that matches your size/dimensions.
