I think the recent spate of failures was on really old ones. Not part of the recall but really old.

Nope, one of the more recent failures was a bridge used for 12 weeks.
But then that's probably the climbers fault, right? I mean, he should have inspected the core of...
I've never heard of prayer being included at PNWISA comps or events, and if they were I would definitely not be cool with that.
I remember back when I took my arborist cert exam that one of the other guys taking the test stood up and tried to lead everyone in a group prayer. The proctor cut...
Uhhhh.... huh? I think that's just clarification dude. Mechanical hitches have been in. Joe Harris used one at the 2011 masters. Lots of dudes use spiderjacks at the comps.

Unfortunatly honesty and best intentions have been trumped by covering your azz so some greedy lowlife lawyer doesn't sue you out of business.

I think the lawyers look like knights in shining armor compared to these callous, calculating scumbags. I'm disgusted.

An autoblock is a setup where there is a prussic attached below the friction device, which has been used by mountaineers and rock climbers for decades to allow one to go hands free while descending on a figure 8 or ATC. That dude was using an ATC, and one without a 'soft lock' side, such as a...

$595. is but a pittance when you consider where the money goes.

I agree. I found the course extremely informative and useful. Even if I never used the material for work (I have a ton), I would still consider it a great investment.
The test is pretty stiff, so if...

The Kiwis feel your pain, use a ring. It won't get sucked up plus it's got less sharp edges to ding your business if you let it freefall. Or you could daisychain the tail so that the stiff piece which attaches to the shackle can do its job, which is to keep the shackle from...

Glad my pain can bring others joy. I'll work on getting better video editing software so my subsequent vids are sharper. Also I will work on never doing a...
I suppose I'm a bit late to this, but in my experimentation I found (what I think anyway) is a better and simpler alternative.
Really, the thing about pulling back the BS is not the mechanical advantage, it's the progress capture that's important. I got tired of having a mini-traxion...
I'll second swingdude, I always keep my leg loops high and tight. Loose leg loops means they move all over the place when you sit down, sometimes crushing your junk.
Other things I'd recommend trying would be shortening the bridge a bit and like simplyarbor said, shortening the webbing from...
Very cool! I would have really liked to see the before and after pics of the oak.
Most times I've done or recommended retrenchment pruning it's possible to see the new crown developing below the flagging leaders. It often can make getting the pruning done without destroying the new crown...
At present, the 'Awakenings' section of this website (and other tree forums) is the closest we have to those type of accident reports. If you want to create something better, I'm fully supportive. You will probably find that you get a much better response for positive action than facile...
I'm also very disappointed by how little staying power this topic has. That there appears to be a major manufacturer selling an absolutely deadly product to our community is, to me, absolutely scandalous.
223, why on earth would anyone share their company accident report with you? These...
Hey guys, I don't want to let this drop. It scares the crap outta me that there are still lots of people climbing on these bridges. We're probably gonna be back here in a few weeks or months with another guy in the hospital after a bridge failure.
Anybody have any good ideas for getting a...
Re: Um... Well, that\'s one way to do it.
OMG this is almost on the level of the American Tree Service vids! God bless you for sifting through youtube to bring these moments of utter hilarity to me.
Bacterial wet wood can damage or destroy the cells' ability to regulate osmosis, leaving the wood 'saturated' and heavier than normal. Was the tree a gusher?
Also, what species? Some conifers can have wildly varying wood densities depending on their rate of growth.
