sorry for such a late response but correct, it is a bottle jack. Great for a back leaning stem with so much volume. A steel plate is nice to keep the top from pressing into the wood. We opted for this method this time because we were felling onto ice. If we relied solely on the skid steer...
Here is a quick Video Edit from a pretty fun crane removal our team did last week. We’re in Minnesota and this job site was on an island on Lake Minnetonka. Basically a brand new 55 ton crane and as always, landing zone was a little tight. Some rubbing but no scratches on the new iron! We’re...
Yes, if I have two wide tie ins, it still swivels a bit to distribute the forces. I think it’s more comfortable than a plate.
What do other people do with their second bridge when it’s not in use?
To me, redundancy is one of the best aspects of a double bridge. Are you saying it defeats the purpose of having two fully separate anchor points? I can still clip a carabiner direct to the minor bridge if I want to distribute forces that way. I personally have a fairly short torso and I hate...
I have been running this bridge configuration for a little while and getting along with it pretty well. No hate to swivels, I just found that having one in it’s normal configuration on your bridge doesn’t really suit my climbing style. The swivel does still help distribute forces in this setup...
I’m about 175 without gear.
I have a relatively new akimbo and tried giving it a fair chance on Scandere (med wear) since it has a higher WLL rating. I really couldn’t find a setting I loved, everything that worked well was closer to wide open. I think that slightly more friction on the lower...
Looks like arboriststore.com has some R and L Powerscenders in stock. Looks like a great product. @MikePowers321 if you have any personally I’d be happy to get them direct from you.
Im having a really hard time finding a bolt on foot ascender for spikes. Something similar to the Buckingham hook and grab. I don't like the CT quick release design because I'd prefer to have the ascender behind the gaff, as opposed to on top of it. Looking to mount on an old set of Kleins...
Okay, thanks for clarifying. If I'm not mistaken, that system is an outlier relative to the rule that gear reduces strength 30%, probably because it doesn't utilize a jam knot. I would expect that to test similarly to the same configuration with a delta link, depending on where the break...
Tony, after reviewing the article, I have a couple of questions. What configuration is "bowline w/ ring" ?
Also, if you were part of the decision making process, why did you choose not to test an alpine butterfly w/ delta link?
I believe this is the article in TCI Magazine being referenced:
https://tcia.org//TCI-publications/tci-magazine/2018/06/viewer/desktop/index.html#page/54
This publication actually states that introducing gear to a canopy anchor SRS will reduce strength by 30% on average.
Thanks for your input...
