The large Tank will help with keeping the hydraulic oil cool if running for long periods of time...most of your high end splitters have a large oil tank...thats all im saying
and as far as tonnage ratio to psi...I run a 75 ton press brake and it only puts out 2500 psi on the pressure guage..there are other factors that comes in to play for tonnage.
I didn't say YOU made any of my quoted statements. I got them off the 'Rugged Split' web-site. And yes, I am aware that a large hydraulic tank will dissipate heat, but THEY claimed it made the cycle time faster. And as far as cooling the fluid goes, 8 gallons is better than 4 I guess, but still, with a 16+ GPM pump, the total capacity of the tank will theoretically be moved thru the system twice every minute. That doesn't give it much time to cool off in the tank. General industry standard for this application and size is roughly one and a half or two times the rated pump size in tank capacity. And that's ACTUAL capacity, not just tank size. Given that, it should ideally have something close to an 25 or 30 gallon tank. Something in the 15 to 20 gallon range would be more in line with what most manufacturers would probably put on it for a tank.
As far as a tonnage rating goes, tonnage is a function of pressure and the area that pressure is pushing against. With a 5" diameter cylinder and 2500 psi, you will get 49,062.5 pounds of pushing force, or 24.53125 tons. To get this answer, calculate the cross-sectional area of the piston by squaring the diameter, multiplying the result by pi (3.14), then dividing this result by 4. For the example of the 'Rugged Split', in which the cylinder has a 5 inch diameter, the cross sectional area is 5" X 5 = 25 X 3.14 = 78.5 /4 = 19.625 square inches. Calculate the cylinder tonnage by multiplying the square inches by the pressure capacity of the hydraulic pump. For example, using the 'Rugged Split' cylinder above and a 2500 psi pump, multiply the cylinder capacity of 19.625 square inches X 2500 psi = 49062.5 pounds. To convert from pounds to tons, divide this result by 2,000 to get 24.5 tons. They don't say specifically what their pump is running for pressure, but I guessed at 2500psi as that's my middle of the road guess. I would doubt it's any higher than that, but I can almost guaranty that it's not the 4000psi it would have to be to get their claimed 37 tons.
With all that said, I'm not saying this machine wouldn't work for you, I'm just saying it's not as 'rugged' as they're trying to make it sound or as their name may imply. It's probably the same machine that's sold at Tractor Supply. I was just there today and they had several '37 Ton' splitters on display out front that looked identical as the ones at the 'Rugged Split' website but I didn't make note of the price.
