Putting the brakes on

[mistahbenn]

Here is a tulip tree on a bank... We took out the branches last week and leave a stick of around 70ft. To stop this log skidding too far, we setup a braking anchor.

If anything would have snapped, I dont think the wood would have gone much further... We used Slings and rope rated to 18000 lbs. We retired the sling.

nice one Ben, only thing I noticed was the sling nearly rolling off the stump, but it didn't so it's all good. Cheers for posting.

 

Here's a pic what we do in that situation....timber hitch at stump, doubled rope bowline on a bight at the trunk section

If thats 70ft then I must be droppin 200 footers every day mate. But still a big chunk of wood and it takes confidence to assume that responsibility, good for you:thumbup1:

 

The rope was rated to 18000 lbs, what size and type is it? Is that the actual breaking load or SWL? Consider also the knotted working load is much less still. That took quite a bounce, smart move with the portawrap, did you let it run a little? Hope so.

 

You seem to have a good eye for rigging Ben, but just remember them ropes have their limits, and are not really designed to catch whole trees. I'll say again, good move with the portawrap.

You are right, it was 70 ft when I started with a 25 inch bar... then i took some chunks off it.

 

ABS of 18000.. The sling took most of the hit, you can see in the slo-mo the timber hitch smoking a little.

Nice control over a big chunk of timber. Good job Benn

That must be the breaking limit of the line....even though it only looks like a 5/8.

 

The force that hits the sling is just the same as what is on the falling log in this case....so it depends which is weaker - the rope or sling (factoring in the type of knots). Look's like a running bowline on the rope, the the strength is halved right there. Timberhitch is not to clever either, especially where you set the pull right against the bite as you did ( I realise you didn't want to squash your portawrap). But probably thats a bigger sling than the rope, so I'd guess the rope would be the weakest link all things considers. But with that said, like Tim pointed out, you nearly lost the sling on the tapered stump....instead of cutting in. Im not trying to sound nit-picky, but you could've still felled the log but perhaps put a few more things in your favour at very little cost. A mound of logs at the far end even (nothing in between) would've lessened such a violent bounce on the rigging. Little things mate. Your best video yet though:thumbup1:

Cheers Reg, yeah all those things went around in my mind before I edited it... but I thought what the hell, its something different. Not TOO much of a high risk bit of rigging. I was worried about it taking out the bank of wires LOL!

 

I should have cut a more open notch to compensate for the bank.... and I should have trimmed up the buttress. Its no fun if you're not pushing the limits Hey, even DADIO liked it! ha

nice work benn, big lump !

The Dadio liked it? Then you've got nothing to worry about. Carry on!
