  1. When you throwline up high just set an anchor line with a pulley containing your climbing line.Draw the pulley with the climbing line up and anchor it to the base with the anchor line.now your climbing off a pulley and it is easy to footlock off it with the vt and very little friction.

     

    this is a shot of footlockin with an ascender with Vt on a pulley set with anchor line.....

  2. What's the recommended safe working load for that zip line/strops/Karabiners combination Rob, and how much would you estimate the top weighed?

     

    If, for example the top weighed half a ton which it easily could have, and it dropped 9ft, the effective weight put on that zip line would have been 5ton!

     

    That's about 2 and a half of your average American family cars.

     

    I'm not sure I'd have wanted to be anywhere near that rope, let alone attached to that tree when someone dropped 5ton on it.

     

    The top probably weighed about 250lbs , easily within the Limits of the gear. Like I said before many times trial and error takes place before using your tools.Caribiners,rope,pulleys say one thing and might do another.I test them out before useing them on a dangerous removal.Some pulleys ,clips ,slings have failed and I dont use them.If I told you about some of the bad gear sold at the best arborist houses you might be supprised.

  3. I always go back to Harry Carey Sr in "angel and the badman"

     

    " Quirt Evans You dont rate a new rope with me"

     

    always use a new rope with each SL job

     

     

    I suppose you all might feel different if you were on one of my SL jobs? I am confident of it.

  4. SOP- Standard Operating Procedure. With a lad in the armed forces i would have thought you might have heard him talking about these. Not being nasty to you mate, I've got a few mates who are either in the sandbox, on their way there or just come back. They're always at the back of my mind esp when i'm doing tricky jobs:closedeyes:

     

    Got it SOP . Never heard it before I guess it dosent make my less than others.Yes I am proud of my Son he is probably one of the best survival trainers in the Air Force. he wants to deploy but hopefully he wont have to.When a tree service survives this long we might just know what we are doing.

  5. Your aims in staff training and care in concept are comendable. But with comments from many, on this and other forums, all questioning the 2nd climber remaining in position whilst topping the tree, plus the susequent whiplash effect caused by the tops premature arrest, on the speedline. Does it not force you to question the method? Those posing the questions, perhaps are experianced and more than aware of the dynamics and subtelties of speedlining scenarios?

     

    I just hope you don't hurt someone with your inability to view the bigger picture

     

    I guess I should change everything I do to make the Arborist board happy?

  6. No, sorry mate - it's an unsafe practice that shouldn't be purported as being SOP.

     

    Maybe unsafe for those who cannot see themselves doing it.Presuming to judge a technique that you can not handle or havent been a part of is offensive to me. This is the reason I dont use subs as climbers.many loose cannons or "cowboys" think they are better than others and try to get too much money.I train my guys and If I can not do the tree I dont send them up. Labeling my work as unsafe without knowing WTH you are blowin is enough to listen too. let people be critics,some can see the new way is better. Oh what is "SOP" ?

  7. so would you advocate using speedlined for decending from the tree

    or did i miss read your post robdog

     

    Why not it is as safe as a climbing line.This version is longer and shows the climber rideing the speedline after the top is cut.

  8. I agree with all you guys have said but remember we have been doing this for many years and mastered it easily.These climbers know what they are doing.That last top cut had to be secured before letting slide down.I taught these guys this technique and it works for us.After the top cut one climber came down the speedline and one finished the wood.never are the two climbers directly underneath each other.

  9. run us through it then robdog

     

    Steve The video tells most of it.The two climbers had maybe 10 webbing slings between them and could set them for the same pulley from different sides of the tree.Two climbers cutting one at a time form either side of the tree.When the first climber cut the lower branches and they hit the pulley they it was time for the other climber to cut his share of branches.The speedline was full and the groundmen let it go all at once.The two were always angled away from the swing of the branches when cut, Bottom climber cut first.

  10. no one gets into my tree!!

     

    Well I guess you dont get the $35 an hour and ceus I provide then right?

    This video was a presentation of an isa workshop hosted by myself Tom Dunlap and Robert Phillips.... cutting edge stuff.If a climber under my employ says he dosent want anyone in "his " tree ... well its down the road he goes.

  11. This is my video of Robert PHillips in santa Rosa a couple oof year ago.I told Robert he was an inspiration to my Service with all of his mechanical advantage tools and tricks that make climbing so much easier.
