that was filmed on a borrowed drift 170, have never used any other headcams, but the gopro looks good, also the newer version of the drift looks good. cheers, there was basal decay with Kretzch, it's one of only 2 trees where I've hired a Picus to get readings to help determine how to approach the job ie rigging optimum sizes etc. Have the Picus readings and cross section of base (post fell) pics if you'd like to see them let me know. There was a gas tank under the tree which we built a temporary shelter over to stop any debris hitting it during the rigging (dead stuff breaking off etc) . Tyres along the retaining wall near the building etc. Lots of prep.

cheers folks, rob arb, what roberts said - Jonsered 2171 (same as husky 372xp), the husky at 1.09 is a 288xp hi Ross, decay/cavity in that stem further down below me, too dangerous to rig down on itself.

this is a fun vid here made for other treeclimbers/workers entertainment, feel free to comment and I'll do my best to answer, enjoy - [ame=http://www.youtube.com/watch?v=gvAyLQbT-XQ]http://www.youtube.com/watch?v=gvAyLQbT-XQ[/ame] (this ones from a while back only just got round to editing it all together)

nobody said anything about 'bigger trees having nothing to do with the skill of the climber' I said which means a good climber will be able to adapt to different trees in a multitude of different situations. .

a lot of people have failed to mention the weirdest thing about this vid, turn up the volume, skip to around 3.57 then listen to the slow motion laughs at 3.59, sounds like a nightmare, ohhhhhhhohoho followed by ack ack ack, could've been a wombat mind.... on the whole, it's a cool vid.

living the dream eh Ben, lol! you wrote these lyrics didn't you? [ame=http://www.youtube.com/watch?v=Kxyu4L1RJmo]Best Patriotic Song About America EVER!!! - YouTube[/ame]

tree climbing comps are irrelevant to this vid. As for the comment about Australian trees being bigger so the work is more technical or whatever is rubbish. You'll find people all over the world with excellent skills in rigging/treeclimbing regardless of the size of the trees. Being a good climber is a state of mind not where you work or how big the trees are. The question is, if these guys had all this amazing experience then why did they think they could stop that timber in that configuration using that equipment? What this vid does show, to trainees in particular is that these two guys with their vast combined knowledge and experience failed to predict the outcome of the experiment.
-
that rope was never gonna hold that timber, there would've been near 25 ton of weight as it hit the rigging, it fell a good 12 feet before it locked up then the rope snapped. Factor in weakening effect of the bend radius of the loaded rope as well and the 25 ton breaking strength is severely diminished. As a workshop it was totally pointless as an advert for an arb equipment supplier it would make me doubt their judgement when it came to asking for advice re rigging. It was a waste of a good opportunity to display some proper negative blocking using proper arb rigging gear.

There's nowhere near enough room in the super/kingcab for kid's seats and all their gear as well. gotta be a crew/double cab, hope this helps.

The Registry of Treeworkers will be an unnecessary layer of bureaucracy. It sounds like something the EU has dreamt up and wants to enforce on the good hard working people of the UK. I wont be taking part in this Registry and I certainly wont be using to find employees.

Watch this vid 1.08 to about 1.12 Look at his left hand position and listen to the brake being activated at the moment of kickback. I've used this test (dont try this at home kids) 100s of times with a 70cc saw to demonstrate the inertia brake being activated during kickback. Forget the red cross animation thing and the video narration - inertia brake is activated by kickback, listen to the operator revving the locked up saw immediately after the kickback- 1.08 to 1.11 - [ame=http://www.youtube.com/watch?v=M1urRc0y64I]How to Work with Chainsaws - Getting Started - YouTube[/ame]

calling yourself Vertigo on a forum dedicated to people who work at height might send out the wrong message how would your scheme differ from the Arb AC scheme? who would be the 'official organisation' awarding the accreditation? The Forestry Commission? The ISA? The Woodland Trust? if it's not an already well established organisation connected with trees or tree management you may find it difficult to get established?
-
and shillo yeah, that's it, cheers.
-
Any ideas?
-
Nice to see some enlightened clients in the US treeseer, is that Fomes?
-
nice one mate, looking forward to seeing it. yep, saw that, very good it is too. The guy who made the Treestuff one above is a member on Treebuzz, 'Oceans' is his member name if anyone is looking for info on how he makes it. Long thread but well worth a look for those interested - some good pics, explanations etc - TreeBuzz Board: new rope wrench tether
-
Just putting this out there for people who haven't seen it, Treebuzz has a forum dedicated to SRT, there's some good ideas/threads. TreeBuzz Board: Viewing forum: SRT-Half the rope, twice the fun! Maybe we should have a dedicated SRT forum on Arbtalk? Steve? what say you? Saw this tether the other day on Treebuzz for use with the Hitchclimber, looks good.

SCOTLAND: FREE 'ARB Approved Contractor' Workshop - 8th Jan.
scotspine1 replied to AA Teccie (Paul)'s topic in AA
Hi Paul, thanks for running the workshop up here, glad I made the trip over to Edinburgh, good venue, easy to find. Picked up loads of good info and ideas for running the business better and was pleased to see the importance that's put on the work site visit during the day the company is assessed. The only thing I was concerned about was that to attain the AAAC status you dont need any treework qualifications as in RFS Cert Arb, ISA Cert Arb etc. Proof of knowledge in areas like tree biology, pest and disease, trees and the law etc. I do understand that you'd be expecting to see and hear evidence of a tree surgeon's/arborist's arb knowledge on the day of the assessment. But I'd expect potential clients to assume an AAAC company would have at least RFS Cert or equivalent? Cheers Tim . -
Hows this for the Arbtalk logo?

I'm talking about a situation where if the prussik slips it will drag the tibloc down as it pushes the micro pulley down and as I've said it's a tool designed for emergency use only in rescue situations on kernmantle rope, that's Petzl's words, not mine. cheers Adam, beat me to it.
-
If the the climber slips from a branch with slack in his line the prussik will drag the tibloc down the opposite side potentially ripping the rope. The tibloc is designed for emergency rescue on kernmantle ropes, not arborist climbing ropes. The system in the video is really very poor from a safety point of view and was cobbled together without any real consideration as to the suitablility of the application. To get back to the original point of the thread, a micro-pulley or hitchclimber is the way to go.
-
elwapo, if this is a frequent occurence could I suggest that you may have made the wrong choice of occupation. Personal safety is critical, not just for your own sake, but for everyone else in the near vicinity. The sharper a Silky is the safer it is for obvious reasons.
-
The Petzl Tibloc was designed to be used in emergency situations, more specifically rock climbing, caving and rope rescue. To use it for advancing a hitch as part of a treeclimbing system would be a mistake that could cost you your life. If you can't see the obvious flaw in that system then you should really try to keep your system as simple as possible, possibly even forget about the hitchclimber as well.
