Tyres would not have made a haporth of difference. nor chains, or even ecotrax. once I went through the crust of that bog it was end of story. I had to dozer in a road of crushed stone just to get the excavator in.
-
Nope. it will climb anywhere even with bald tyres.
-
Yeah. But the ones in the US are now built by Dave Nordgaard at TNT to my design.
-
Sure is. Osa / FMG250. very good machine, very well balanced, will climb anywhere.
-
WHy not just buy one?
-
Details?
-
Excellent Machines in my opinion. Will outperform many bigger chippers.
-
EH?! All Northerners are like that. Plenty of us real men up here still
-
Sorry Dave, Just teasing. Its a bit antiquated, the seals in the rotator will probably be tired, but for £150 squid its a steal. It looks like it is a continuous rotation unit too.

ehw. yuck. About 130kgs....

not really, the mill I'm thinking of was stoneclough road, Kearsley. We cleared a few big sites down there.
-
Hey Phil, welcome to Arbtalk. Where in Bolton was your center? down by the old mill perchance?

Accurate terminolgy is good, but I'm really not offering advice, just my own experience. I would not build my own again, I'd just buy the silvey. And so far my knowledge has enabled me to design and build logsplitters and chipper infeed systems, rebuild hydrostatic forestry transmissions, wire and plumb harvesters & forwarders, install cranes, hooklift systems, heavy winches and crushers. Silly really as I hate hydraulic oil.

OK Mr pedantic. to give you 45 tonnes of pressure with 2000 psi you would need a ram with an internal bore approx 6 inches wide. Given that we're talking about pushing trees over, I personaly prefer a rod that is as close to the internal bore as possible. In the case of the silvey, its identical, as its a one way system with sprung return. As to the amount of force needed, you can use as little or as much as you like my friend. I was merely using the silvey (world market leader) as a comparison - when we built our own version, we built it very similar. And if I want to do it without cutting into the trunk, I use my Excavator.

Yes, Theoreticaly you could get a tractor powered ram to give 45 tonnes... you would need a ram with a 6 inch rod, which in turn would be probably beyond carrying, and would be near impossible to cut into the back of a stem...

& jobs for the boys.

Ah. well the tractor hydraulics option is never going to work, as the pump will not make the pressure. As for having to use a tractor just to power a felling wedge.... The air jack idea is a good one though, if you did a little re-engineering on the jack. The thing about the proper Silvey jacks is that they are light (made from Aloominum) and very powerfull - 45 tonnes from a tiny jack...
-
I like that truck:001_smile: I liked Feurte, although its a barren landscape. SOme parts feel like you've landed on the moon.
-
60ft?!? why so much hose? we used the same as the silvey, about 6 ft why do you want to use an air operated jack? The standard manual pack works fine, bit hard to drag a compressor into the depths of the woods:confused1:
-
Will probably prove excellent at stopping any further conversation.
-
Ever see the pump components on one of those hand operated portapacks? the pump section is about 3/8ths of an inch and an inch of stroke. Very low flow but very high pressures. Same as you see on hand operated hose swagers. No need for two line hydraulics, as the rams are one way with sprung return. just open a valve and let the fluid return.
-
Not enough pressure. You need about 10,000 psi...
-
The seals go hard without use over time. We used a set of industrial compact rams, with a portapack hydraulic pump.
