2 climbers?

[RobDog]

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.

That's called russian roulette isn't it ??

I'm not suggesting you are working outside the limits of your lads capabilities or the gear you use.

 

It is only my opinion that having two climbers up there increases the risk without having any massive benefits.

 

Christ, we've all been shaken around a bit at times, but I'd feel pretty bad if my saw lashed my oppo round the chops (love the Dolly Parton analogy Dean).

 

You have your way of doing it mate. Fair play to you. Climb safe.

Why did the 2nd climber not leave the tree before the top was cut? Like someone else said, wasn't his part by this point completed anyway. IMO, there would be no real problem having a climber attaching slings at one side of the tree whilst the other climber was cutting on the oppersite side of the tree! I can see how this may speed the job up, but i would definately want the second climber on the ground before knocking the top out! And if the speedline was tensioned in the video, then i see no advantage of this - much safer to slacken it off and re-tension it once the top and been arrested and attached!

 

But, whatever the rules say here in the UK, personally i would have no problems riding the speedline on the way down, i just wouldn't want the lowering line attached to slow me down!

 

I really enjoyed reading all the comments on this thread - very interesting how professionals opinions can vary so much!

I really don't see the problem with there being two climber on the Spar when it was topped out.As has been stated the load was within the capacity of the equipment and the integrity of the Stem.

 

I think its alll relative to the size of the timber and rigging tackle you are using.

Personally i thought it was rubbish. And the hooting and hollering is very very dull.
