Circus Knots
« on: October 30, 2010, 07:49:10 AM »
I was at a circus last night with the little ones and some some interesting knots.  I only shot a couple as I was looking quite like a freak with zebras around me and I'm taking pictures of the ropes LOL  :P

Now the fun part...NAME THAT KNOT!!!

I think this might be a slipped Strangle

I think it looks like the scaffold knot ABoK #1120

Derek

Thanks for the enlargement.  At first I read your "slipped Strangle"
as "... noose" and was going to ask where the bight was and the
end ; but now I see it as just what you say (well, make *double*),
but loaded on its tail --yes, thus a noose in effect.  And, as Inkanyezi
pronounced, the Scaffold knot.  --perhaps chosen in part for
its *tamper-proof* security!?

I think I found the second one the most interesting.  It was a double half hitch but wasn't tightened down...this was holding the tent up  :o LOL

European safety standards can be funny sometimes   :D

Are you sure?

In your third picture -



-  we can see the vertical rope seems to be under tension alongside the flat strapping which also seems to be load bearing (and strapping of that dimension can hold a major load).

Then in the shadows off to the left, we can see another rope under tension, it seems to have been brought down to the ironwork, a bight wrapped twice around the structure and tied off with a simple hitch tied with the bight.

Is it possible that the rope in the forefront is in a similar situation, i.e. going right down to the bottom of the structure (we can make out some wraps behind the strap tensioner), and the load taken there with a couple of turns of a bight - leaving the rest of the structure we see as simply end tidying.  There certainly does not seem to be any parts of it under load other than the single vertical run...

Derek,

I was referring to the second picture.  You can see the load is coming down and aound the pole and hitched once (load bearing) and the second hitch was loose.  I can see with that much slack on it that in the event the second hitch was needed it would have tightened up though.

I can see I'm going to have to get some better shots next time for us to examine!  8)

1) I don't think (but you were there...) that the rope is doing such work;
rather, that the webbing/tape/strap(ping) is the workhorse --and, as Derek
notes, it can be under MUCH load (wow, it can really feel tight!)!

2) It must also be remarked at the Scaffold-hitched attachment
being to this apparently loose loop of what seems like Two Half-Hitches
(of a bight) !?

So, really, what were the ropes doing, exactly, and the tape?
Perhaps the latter holding most force and the structure (skeleton)
with the former the cover put over this (the skin) ?

Thanks,
