small diameter logging with stroke delimber harvester
« on: January 21, 2017, 02:04:41 PM »
Any chance anybody uses or have used them? They're popular in Europe. I'm interested in the small acreage/ small diameter market. [ 1st pine thinnings, and sourcing logs for firewood business]. I see farmi makes one for small-mid size excavators. Probably the only dealer in the states?? Hahn machinery in minnesota also makes a CTL head recommended for 20-25k machines. I'd like to keep it small enough to haul myself for the smaller jobs

I've wondered the same for first entry pine. Our Ponsse processors seem like overkill in it, and it's a struggle to make a profit in it in a lot of stands. I have a hunch those stroke heads would delimb it better, too. Especially in warmer weather.

Yeah, from what I understand, the stroke harvesters are stronger than the roller type? That's probably more the case with smaller hp machines. Not sure on price. The small Hahn roller ctl is 80k new. I would hope the stroke type are cheaper

Stroke harvesters are capable of more brute force, but usually won't work as good as a faster roller feed head.  Consider a swinging axe, vs one that is slowly pushed.

That aside Kesla makes a nice looking little stroker, and I believe there was a Tapio stroker as well

The little Arbro 400 heads appear to be gaining popularity again around here, they are commonly mounted on mini excavators.

What is the necessary flow required for a stroke? I thought most were mounted on midi excavators. We have a 35 Kubota and remember it being to small for recommended gpm.

Quick Google search says 45-80 liters per minute and 2500 psi is all that's required for the Arbro 400

I am also looking for a small roller head harvester for my Bobcat E80
I am leaning towards the Hahn since it is made in Minnesota.
so 75k + controls in the cab + shipping = $$,$$$
still considering it.

but then with a stroke i could count the number of strokes and judge how long the log is.

so far these are the heads i have found

the prices i list are NOT in concrete
 logmax     928a =  too big
 hahn     hsg-140 = have not been made in a few years, they have the parts, Made in MN, $75,000 and up
 hakmet     275R
 hakmet     375R
 hakmet     Arbro 400 = $45,000 and up
 hakmet     Arbro 1000 = $64,000 and up
 Naarva      S23c = $26,000 and up
 Naarva      S250
 Naarva      S250r
 kesla     16RH
 kesla     20SH-II
 ponsse     H5 = need 50 gpm, 100 hp

I looked up info on the arbro 400, and it looks like they have a measuring system somehow for lengths. I see hakmet has tons of dealers in the states, so that may be the best route for service and parts

Good evening.  I had too reply about a stroke head.  I have a 2006 tapio . It limbs well but that's about the only good thing I can say about my head . My head has a major flaw in the design of the saw motor. The shafts are too light and the only thing that holds the sprocket on is a 6mm bolt that breaks every time .  I have spent 1000s on it and rebuilt it all new three times in less than the 2 years I've owned it  . These shafts are 800$ each  plus labour. Mayb the new ones have changed but my head has pretty well ruined me  because it is poor set up.

Stroke processors are inherently slower but typically less expensive. Measuring length  is simple for either.

..........sprocket on is a 6mm bolt that breaks every time .....
On my Multitek 1610EZ the saw has a 1/4 inch bolt = 6mm
the cylinder that moves the saw to cut has a pressure relief valve.
does your Tapio have one?

may not look like this but should have a set screw
 

 

in photo below, above hose is from saw motor, left hose goes to cylinder, front hose goes back to the tank.

I've changed that valve.  We have now drilled holes in the coupling and put set screws in it too hold tight on the shaft. Got it all back together again yesterday so hoping for some luck today  with it

I've changed that valve...........

good, but did you adjust it?

also please update your profile so we can see where you are at.
City, state, country. or the equivalent. do not need street address.

example, my profile shows Glendale Oregon, that is about 2 miles from my place.

Yes it was stuck on 160 bar and supose too be at 80 . We run it today with no issues   Would that valve not working properly would that wreck my shafts and break the 6mm bolt ? We are from Nova Scotia Canada.  Thanks for your reply I've had this machine going on 2 years and my 1st one. Nothing but trouble with the shafts. No support here for tapio heads as well . I had a log Max mechanic helping us thank goodness.

yep, 160 vs 80 = twice the power that should be

glad it is working.
here is a link to my headache.

Is it a keyed shaft?   Have any pictures of the saw  area?   Is the sprocket shimmed to the correct alignment with the bar?

How small is small ?  Beer can diameter?
Might look at the overall operation  machinery requirements.  Fell, move to skid/landing, processing and loading.
Small / part-time or a 5-6 day a week/ 10 hour per day or longer operation etc.
Do you want to use a chainsaw for a little bit of too big logs etc ?
See if you can get rebuilt (to a high standard) roller head to fell, delimb and process (Finland - some firewood operations use roller heads to process firewood).
Drop off the head and use a grapple to load, if self loading trucks are not economic (one or two machine operation - with a good profit as a minium goal)
Used logmax 928 or waratah 412 (rebuilt) on used ten tonne excavator with a few mods etc.
