So far its living up to expectations & only needing a few very minor changes.

Its been a long time coming with many hurdles along the way but finally its ready for use. The latest addition to our processing options. Dunn 420 processor log crane / grab 3m Kellfri log deck work platform 2.8L Iveco diesel engine 3500kg trailer All combined to make a super mobile firewood processing unit. We are still not sure just how much we can do per day with this beast, but are expecting great things after the results we got on a one day job locally this week. In the morning the client (a mate who has been using processor for years) was running the processor & did 12 IBC's. For the afternoon session one of my operators ran the processor & did 18 IBC's. Going on that we should be able to do an easy 35+ IBC's per day for most clients. This is a big increase from the 25 IBC's we do with the RIKO WP30 toad tow. We are currently for a limited period only hiring out for the same rate as the WP30. Travel will cost slightly more. https://www.facebook.com/RichFirewood/posts/1857140634444205 Quick look https://youtu.be/5xPPR3JxSww Loading the deck https://youtu.be/icaoo6o7NjU These speeded up videos are about 10 mins long & roughly 10 seconds = 3 mins aprox Client processing in the morning https://youtu.be/UQ_WC_cNZYM One of my operators processing in the afternoon https://youtu.be/2YFoEaUEStk

Used the BR800 I won from https://www.facebook.com/ArbCompetitionsUK for the first time today. All I can say is OMG its a monster.

I am finding that on hard use cutting big stuff you can get 2 bats to a tank. On lighter use the second bat would run it dry after about 2 bars of charge.

There area lot of sellers using splitters as for some wood its the best way.

Oddly another mate asked about them yesterday. Before you do anything watch a video of it in action. Its slow and a faff to use. A full cycle has the operator, reach up high with one hand while holding log clamp down. Pull down to a low position, reach left to split. Lean right to feed log in. Last 3 cuts have to be manually pushed in. Ps remember to as to see the IVA certificate that proves its road legal.

That makes all the difference. Doing it domestically removes the need for performance. 1.25m3 per hour would not be viable commercially.

High tonnage split is great but without fast cycle times you wont produce much volume.

You dont see road tow WP's for sale that often & they sell quick. I nearly sold mine to buy a higher spec version. Could have sold it 10 times over.

A mate has just had a quote for a road to wp36 10 ton but without any extras & it was about £18k inc the VAT.

Dunno about the Jappa. I would see just how much you can produce in a day & set the rate based on that. Excluding travel & accommodation I charge £250 with one operator & £350 with two. With two operators on good wood / good site we produce 25+ IBC's per 8 hours onsite. Thats over 30m3. With a 300mm max cut you would already be potentially 36% down on production compare to a 350mm max oif all logs were at max size. Especially on lorry loads as they tend to be nearer the top end of size spec. Then comes cycle time (cut to next cut). The Japa looks ok on that but lots of down time sorting the next length. I am oddly in the same situation as I have a second processor I am bringing online very very soon. Currently I dont know what it will produce in a day so cant set the rates. Lucky for me I have a very local firewood dealer mate so I can do a day or so there & iron out any issues & see what it is capable of compared to my first machine. Then I will set a rate pro rata based on production & running costs. I already know travel costs will have to go up as towing a full 3500kg will cost more than 750kg. In your position I would buy the best machine you can afford for your needs. Thats how I ended up with my first machine.

Japa 305 Mobile Firewood Processor - Ben Burgess WWW.BENBURGESS.CO.UK • Road tow • Honda petrol engine • 300mm chainsaw cutting diameter • 5.6 ton splitting force • 3.8m output elevator £12.4k I do contract processing. I think that machine will be too slow & only handle small stuff so affect what you can charge per day. You not going to be doing lorry loads of processor friendly stuff with that. Best one out there is the WP36 but its well out of your price range in road tow spec.

For what you want I would use a fixed grab. I have one on my 3.5t. I use it for logs, rocks, raking, digging, rooting, grading / leveling by holding a beam & many many more jobs that a rotator cant do. I had mine altered so the 4 tines were on top & 3 below so it would be a better rake.

Been a while since I looked at rope spec but from memory dynamic will stretch about 25-40% & static (or more accurately semi static) only stretches about 10% ish. I think true static is sub 6% at a % of its rated capacity. So in your 40m example he would decelerate over 4m. Still very very harsh compared to dynamic over up to 12m. Either way dont fall on static kit. Its not for that. If you are going to have fall potential use dynamic links or have an arrestor of some sort. Down side is in a tree falling further will let you hit the tree. So back to dont fall

Yes but understanding fall factors helps you manage risk by for instance not climbing past the anchor. Did some googling (dangerous I know) on the max kn a body can take. This value comes from military studies on paratroopers: the human body can withstand a maximum deceleration of about 15 G, or 12 kN for an 80 kg mass. Whilst HSE say 6kn limit. A deceleration of 12G is considered survivable in a parachute harness, i.e. a harness with torso enclosing straps and shoulder straps. For such harnesses the NASA/AGARD researches indicate a 5% injury risk at 12.1G, but the differing posture, physical fitness levels, harness attachment location, 'wearer comfort' and other factors have influenced the advisability of 6G as a maximum for users of industrial harnesses. https://www.hse.gov.uk/research/hsl_pdf/2003/hsl03-09.pdf

I wonder if there is any mileage in kiln dried loosing some energy value as its heated so might vent off more volatiles.

Fall factors would still be important. They define how many kn is felt by your & your gear. Lower the factor the less impact you / gear feels. You can never have a factor greater than two. But longer fall distances adds impact power. One thing I always remember is that you can climb above a nylon sling & get a factor 2 fall & it will be ok but do the same on a dynema (sp) type sling & it can snap. Tree climbing is not my thing but I assumed you would have your main anchor point & then intermediates / redirects nearer where you are working. I guess that would end up with the tree festooned like tinsel on a christmas tree. Sounds like a bit of an epic. Far to many come to a fast stop on the ground. I have seen belayers jump off a ledge to take slack up & save the leader. Other times its give slack so they drop past the high impact slam zone. Interesting stuff looking at falls & forces.

Did you not see the word static? That calc works for you. Using static over dynamic doubles the impact force.

Or this one for static rope Fall Factor Calculator FERFORGE.TRIPOD.COM how to fall

Do you not use fall factors? So a fall factor of 1 is when the distance you fall is equal to the amount of dynamic rope in the system. Fall factor of 2 you fall double the ropes length. Rock climbers fall many many meters above the anchor but have more rope out to absorb the forces & get a soft catch.

A plug in 12v charger using the cig lighter port will be limited to about 120watts (10 amp limit). Thats seriously slow compared to a 500 watt one. Just checked spec Its WORSE than that. 80 watts charge. So about 4 times as long to charge as the 500 watt mains one.

I love sycamore. just as good as Ash. Dries quick, burns hot, super easy to cut & split. If only all clients jobs were sycamore lol

I think having the smooth sheet on the outside will be easier to use.

As above if its got the wedge its a standard type bar. If not then its a forestry bar but no one has found a match so its direct from Riko only. Would be good if a bar dealer could physically check the bar & match one up.
