brainwave

[garry kidd]

at the moment im currently working as a door supervisor on bars and pubs until work pics up for me and basically i had a brain wave for a skiline basically a double drum winch powered my tractor or unimog 1 line for lowering and raising the carrage and the other for pulling in the wood a basic roller and hook as a carriage with chain chokers to wrap around the timber and some form of steel frame work to lift the cables higher enough to clear the stumps and what not

 

 

was this a bit of a mad moment in the freezing cold last night or is this used by any 1 or ever been atempted

Is that not what a skyline is, or am I missing something??

[garry kidd]

sorry i meant to say rather than a purpose built skiline just using a normal pto driven winch

its a good way of winching stuff out but very slow if you were talking about shylining for clearfell. But for a trick up your sleave on the right job its simple enough but the problem you would have is the lines are at the same height at the landing zone, you would need your top wire hire for it to work effectively, thats why the old ones were like a tripod on wheels. And you wont be able to send the wire back down you would have to drag it down or join the 2 together and have the top one high, so you could send it back and forward, but this is all in my head and i reckon it would be a nightmare to do and set up correctly to work efficiently. If you are after setting yourself up as a skidder or winching service then i think you could find a niche market with the right bit of kit, i would buy the little skidder in classifieds, the mog one of woodmads, it is the ultimate quick, on road off road skidder for small scale work but still has the grunt for big hardwoods..

Seen it done with a three point linkage double drum and then a pulley block mounted on a 360 or a Drott/Dozer and that way you can move it quickly across the bank too as both ends of the system are mobile - worked well and dead cheap as using machines that were already on site.

 

Forgot to say - did have to take the cables off the drums and run one long one as otherwise it didn't go through the pulley.

missed a bit

[Stephen Blair]

was that with both ends linked so you can move it back and forward chris?

[Chris Sheppard]

yep - one big loop as such and fixed chokers - didn't see the chokers up close but can't be too difficult to make something to suit.

Its called high leading- look it up on wkipedia..

 

Some one else had the idea in 1904, sorry to burst the bubble..

 

It can be a bit of a carry on but suits certain situations.. and yes my mog is just the tool..

I worked with one years ago we used a double drum County and spar trees.
