'Soft Technology' SRT Systems

Re: \'Soft Technology\' SRT Systems

Ya, Its aid climbing. A lot of what I do is done by gaining access by aid climbing. But those slings don't come with the safe ability to set them with a throw cord and ball...... sucks. It limits me to use all the tricks I have in the bag.
 
Re: \'Soft Technology\' SRT Systems

I think a factor that relates to incident rates in tree work is the criteria for entry into the field.

I'm not posing an argument for having more or less restriction, just to say that if a person is hard on luck but has an acquaintance that needs a tree worked on, you suddenly have an untrained tree worker with a potentially high level of exposure. If that person, or anyone around the work site is hurt or killed, now you have a a tree work related statistic that gets lumped into the entire pool. True professionals swim in that pool, too.

If Channel 6 has a tower that needs a tweak at 400' up, we can be certain that a professional will show up to do the work.

This is just a fact that we must accept, until someday, everyone in the general public holds a sentiment that tree work is most often worth hiring a trained professional to address.

I also agree, rope on rope connections need significantly more data to reflect upon before criticizing them.
 
Re: \'Soft Technology\' SRT Systems

cant you take a regular steelcore lanyard, and use that?

seems like it can be as simple as using a regular flip line (already rated for life support) there is the small eye that is crimped with a thimble, the you can use a prussic cord and carabiner as the large ring, there you go, adjustable steel core ring and ring sling, or you can throw a carabiner into the second thimble at the other end of the lanyard and you have then a one length steel ring and ring sling.

just my $.02

It would way more excepted by the climbers if it is purpose built. A lot of guys have a hard time looking past personal ingenuity.

And this is one of the problems that I see in other rope trades. A lack of being able to 'think outside the box.' Or maybe some of them have already brought up suggestions, only to have them shot down by their peers?

How do we make others (especially those that are in power) see the benefits of personal ingenuity?

Re: \'Soft Technology\' SRT Systems

You could install that sling with a throwbag couldn't you? Retrieving you would need to add a small catch ring.
 
Re: \'Soft Technology\' SRT Systems

You can add a ring but it will be two rings and two more bieners as well due to we have to use two slings (one for main line and the other for the backup. The less I have to put together to accomplish what I am going for the better.

Small companies would have no issue with thinking past the norm but the larger companies don't due to having to set a cross the board standard that each employee is required to follow for insurance reasons. Also some large companies that large companies due work for require a standard of operations. So each employee is trained or supposed to be trained by the same standard, this way when a climber that does not work with a crew ever comes across the country to work with them he/she knows what they are doing and can fall seamlessly into the job. If one crew adds one kind of gear to accomplish a goal and another crew does it in another way it causes banging of heads after a while. One thing that helps to understand where I am coming from is this..... For the most part tree climbers love the craft of climbing and love to push the industry forward. Most industrial climbers I have ran into look at it as a means of money and that is it. They would rather be sent to a job that requires loads of time on stand by and not have to get on rope at all.... sad as it is. There is a new generation of climbers that are coming in now that love climbing and do as much as they can even when not at work.

back on the subject though of the slings. Just like in tree work it is easier to have a purpose built sling rather then having to use more gear to get the effect.

Jim, maybe you could tell us if there are specific regulations on when you can and cannot use ‘soft anchors’ i.e. cambium savers, versus ‘hard anchors’? I was looking through my North American Working at Height Handbook, and on page 89 they show an arborist cambium saver as an acceptable anchor sling (provided that it meets 22 kN breaking strength). Again, I would imagine that there would be times when you would not want to use one, e.g. when you are anchoring over an I-beam or bar joist.

Kevin, as I said above, if the cambium saver can be used, than yes, it can be set and retrieved just as we do in the arborist industry, without having to add any extra hardware. In fact, in the North American Working at Height Handbook, they demonstrate the technique of how to do this, AND they say “These techniques and equipment are taken from the arborist industry.”

Either way, as Jim has pointed out, you still will need an additional backup anchor and sling (plus rope attachment). Having 2 attachment points to one rope just won’t cut it in SPRAT/IRATA industrial work.
 
Re: \'Soft Technology\' SRT Systems

Yup you can use our cambium savers. The only issue I run into is they tend to not be long enough a lot of the time. For an example, I can not use any pipe as an anchor/overhead if it is less then 6 inches in diameter. A lot of beams and post are large as well making it impossible or just a bad angle for the cambium savers......... Then again I have not looked to see what sizes they have out there...... The hand spliced rope ones are great but just not on sharp edge metal, so it would have to be the thick flat strap type.......... Just looked disregard my last SEVERAL posts, I stopped being lazy and just went over to Treestuff. Please no one tell my wife I just admitted to being lazy, thank you.

No worries Jim. You're safe with us here on TreeBuzz

Treestuff has what you're looking for. And if not, Luke and Nick can probably get it for you.
 
Re: \'Soft Technology\' SRT Systems

Not quite SRT related but, when I read about tree climber/worker accidents in TCIA or the like, a lot of them are not by professional tree workers...similar to rock climbing accidents that are actually by hikers taking a slip. Would be more accurate if we could narrow a little more and provide info related to professional workers only. I think this would be a more accurate and give us better info on how to avoid these accidents.....
 
Re: \'Soft Technology\' SRT Systems

Is anybody familiar with the Larsen and dill study on prusik failure? I read about it in this "article" I found. The info doesn't apply directly to arboriculture, but I found it thought provoking.

http://www.sarinfo.bc.ca/Library/Skills/prussiks.skl

The loads they had on line in the tests mentioned seem extreme, but I like that the second writer brings up not trusting the common practice as infallible.

I still think soft tech is no worse than mechanical, but I am curious to see what happens to the rope and hitch if I dump 200lb into systems (srt/ddrt)with slack in them.
 
Re: \'Soft Technology\' SRT Systems

Yeah, Poalo did a good job on that one. The link you posted was also good but shows how important it is to understand just what and how things are tested.
