OK, I'm interested....who has one of these Hypersplit splitters to tell me more?

I've watched a couple videos and the speed is not super evident but cutting cycle time in half on a traditional platform has me intrigued.

HyperSplit Log Splitters

 

Found a prior discussion here: Hypersplit wood splitter?

 

Just a couple of random thoughts, at a glance at their website:

They don't specify pump sizes on their machines.

The 20-ton model lists a 7HP "Rato" engine, the rest do not specify engine size or manufacturer. I admittedly don't get out much, but have never heard of a Rato engine.

The log length is pretty short on the smaller machines. Less length to travel means faster cycle times, but can be a problem if you use longer chunks.

3/4" inch hose is good, as are 3/4" fittings, but moving fluid that fast generates heat. The tank sizes on their splitters don't look any bigger than slower splitters, so less capacity to absorb/dump heat.

Cylinder sizes look about the same as comparable splitters, maybe? They don't tell cylinder size either. So I'm curious, besides the shorter stroke length, how they achieve the speed? A higher flow pump would be one way, but again that means more heat and the need for a bigger reservoir. Stage pressures could be adjusted so the low pressure/fast stage stays in longer before you hit the high pressure/slow stage, but that would sacrifice power.

These are not criticisms, just design observations. I'm curious about them too. How do they work? LOL.

 

They use a ten horse on their 32 ton, so I am guessing the 'speed' comes from a larger pump essentially. That model also looks to have a fatter reservior than other of similar sizing. And yes, I'm thinking the same as others will...'what if I just up the sizing of engine and pump on my unit?' I could probably build an ugly GX390 out of the shop's boneyard.

 

I just bought their 25T version with B&S engine last week and was going to post about it. Obviously not a ton of use yet. I let it run for about an hour at different engine speeds, cycled the ram a ton of times and pushed about 10 cherry rounds through it.

Speed really comes from the shorter stroke length and it does have a much quicker return time than the equivalent Huskee that I have primarily used in the past. I think it is 8 or 9 gal hydro reservoir. Cylindar got warm, but didn't seem crazy....I also didn't run it all day yet.

Accepts 22" long logs. I like the log catch on both sides, which you don't get on all competitor models this size. Seems similar build quality as all the other box store ones. I figured if the quality and overall performance is equivalent, but I will be able to save a ton of times over the next 10 years, not a bad deal.

I'll post up some pics later today. Let me know any specific questions and I will try to answer.

 

Possible to get a picture of the pump's ID plate/Numbers? Looks like the YTL units give 24" for log length capacities. I rarely make splits over 20" anymore.

 

Yeah, I can grab pics this evening.

Owners manual just states 16 gpm hydraulic pump.

 

These splitters look like yet another option built by YTL. (Chinese manufacturer of most big box/farm store splitters, and are known for fudging their power and speed specs)
A 25 ton likely has a 4" cylinder, so with 24" stroke/16GPM pump, that would make for a cycle time of 9.1 seconds. (assuming a 1.5" ram, and full stroke...a 2.25" ram would knock that down to 8.2 seconds/full stroke)

 

I have the 25 ton that I purchased about a year ago. It has a 6.5 horse Briggs with a 16 gallon a minute pump. It is very fast and I really like it. I modified it and put it on a trailer so it is now full time vertical. I think T. Jeff took a video of it working at the bucking trailer , you can find that Live from Walts GTG. There were so many features that I liked , the large pump , the large lines to cylinder, large ram , these all add up to a fast cycle time. I purchased it on sale for 899.00 regular price is 1299.00. Probably won't ever put a log lift on this splitter because this is primarily to be used with the bucking trailer .I am really happy with this splitter and would buy again.

 

They say 5.8 second cycle time , I timed it once and near as I can tell it is around 6 seconds. I am sure they probably fudge on power specs but it seems to be as powerful or more so than my 20 ton Wallenstein

 

My YTL's specs were legit, both cycle time and rated pressure.

 

Well, you know as well as I do that the math ain't mathin on a lot of their models...sounds like that's not always the case though.

 

Interesting. So they're shading the "2 GPM per HP" rule of thumb a little bit. Sounds like they make it work out well, though. Nice!

 

I am not sure how the math works to calculate cycle time but specs on the cylinder say 90x60x508mm

I just did a test myself. Let the machine warm up and timed 10 independent cycles. Avg time was 6.89s. Maybe not what they claim, but still way faster than the other box store stuff.

 

They are stopping quite a bit short, so I am sure that helps on the cycle time. 1.75" to the feet, over 2" to the base.

This was the only marking on the pump

 

I think a lot (most of?) the newer ones stop short like that now. I read somewhere that was an effort to keep from severing human limbs. I don't know if that's factual or not.

 

I watched a ton of review videos trying to decide which unit to get and almost all of them pointed out that the wedge stopped short on all of them. I was just surprised by how much.

 

tractor supply, at least near me has the 22 ton model on sale right now.

 

Ok, so that works out to a 3.5" x 20" with a 2.36" diameter ram. Which gives you a 4.8 second cycle time with a 16 gpm pump.
And IF its set at 3000 psi (it's probably lower) that makes it 28,863 lbs splitting force...well short of 20 tons, let alone 22, or certainly 25!

That's what I'm talking about, when you actually do the math, most of these splitters are over hyped...often in the hydraulic power department. It's easy to find out, just install a pressure gauge inline, then do the math.
My old 23 ton Champion worked very well, pretty much nothing would stop it, but one day I noticed that the factory hydraulic lines were rated for something like 2700 psi (I don't recall the exact number any more) and it would have taken 3500 psi to make the tonnage that they spec'd it at...I never put a gauge on it before selling it though...point is, I really doubt it made 23 tons.
One of the people I talked to at the Paul Bunyan show this year said that most of the big box/farm store splitters are rated by adding the both the tonnage out, and in, to get "total tonnage" which is what they rate it at then.

I designed this and had it made up to allow for the wedge to go completely thru the wood I am splitting. Works better than using another piece of wood as a backer to what I am splitting.
