most people compare if there’s a number they think they’re comparing two models. And if that number is bigger than a competitor we can sell our machine.

The most common way is they take the highest rated component maybe 3500 psi or 3700 psi and multiply that times cylinder area and get an inflated tons. Even though the system is operating say at 2400 psi.

very few actually operate in 3000 to 3500 psi range because the cost and availability of components changes considerably at the 3000 psi point. Not to say that lower quality components can’t be pushed a higher pressure, it’s just that for industrial components 3000 is a traditional boundary where hose and pump technology changes somewhat.

Basically just compare cylinder diameter between different models and ignore all the tonnage ratings. And look at pump size and cycle time and probably most important is ergonomics and overall quality.

I asked a floor salesman one time how they were claiming X number of tons with the 4 inch cylinder and the pressure. he had apparently gone to product sales class. And memorized everything but understood nothing, because his explanation was ‘our cylinder is so much more efficient than the other companies’

Ditto.

How the Foxtrot do you think a 9 hp Honda can generate 25+ tons of force and get something done...??? Ain't happening.

Multiply the surface area of the cylinder plunger (R x R x 3.14156) times the

Darn salesmen..............

surprising what it could do. I use it to do small amounts or kindling or indoor splitting now.

I've since bought a Forest King farm model hydro splitter rated at 30 tons.

I know it can't be pushing 30 tons of force at the blade so its definitely false advertising.

It does good though and was on sale so I'm happy with it.

SO Many times I get asked if I put a bigger engine on my existing splitter will it cycle faster? No. More speed requires a larger flow, which then takes more horsepower to turn that larger pump at the same maximum pressure.

Here you go

It gives it to you in lbs so divide by 2000 for tons.

And buy what to replace it? They all play the same BS game. As far as i can tell none of the consumer splitters actually have workable tonnage numbers. Buy what will work for you, accept the claimed specs are BS and move on.

You may get a faster cycle with a larger unit. The log splitter can work hard. My complaint is that a full tank of gas outlasts 6 plus hours

The point is that my bottom of the line machine will split anything I load. Tonnage smonage

The surplus center has the hydraulic pumps and cylinders you match the pump to your engines hp.

My last homebuilt splitter was a 5” bore x pi 3.1416= 15.07 x 3,000 psi= 47.124 tons. What she didn’t split she cut through it.

I built a 32ton splitter with a 3,000psi with a 3.5” bore cylinder for 25 years homemade. My only problems was the free I beam was too thin but a sledge hammer would fix it when it bent but not often.

I have extra I beams here is anyone in ct or nearby is interested affordable.

No, it's pi x r squared x pressure / 2000, where r is half the diameter of the bore. Franny K came up with the right figure above.It’s pi time (x) the bore, times (x) the hydraulic pressure.

5” bore x pi 3.1416= 15.07 x 3,000 psi= 47.124 tons

(pi x 2.5 x 2.5 x 3000) / 2000 = (6.25 x pi x 3000) / 2000 = 58904 lbs / 2000 = 29.5 tons

Cord King?

Seems like it used a 6" or 7" cylinder if memory serves me.

7" cylinder at 3000psi makes about 55 tons of force.

It’s pi time (x) the bore, times (x) the hydraulic pressure.

Me too. H beams, some large ones, 16-18" 1/2 and 3/4" flanges.

I'd about give to a good home at this point. Have a bunch, probably 40-50 of them in lengths from around 6ft to 16ft.

And just like that huskybill's 47 ton splitter became a less than 30 ton splitter.No, it's pi x r squared x pressure / 2000, where r is half the diameter of the bore. Franny K came up with the right figure above.

(pi x 2.5 x 2.5 x 3000) / 2000 = (6.25 x pi x 3000) / 2000 = 58904 lbs / 2000 = 29.5 tons

And even that assumes that the pump actually develops 3000 psi. If it is less then so is the tonnage.And just like that huskybill's 47 ton splitter became a less than 30 ton splitter.

True statement, and few do or are set that high.And even that assumes that the pump actually develops 3000 psi. If it is less then so is the tonnage.
