nice shots, like the common Fallow buck, in a park?

Self employed climber required in North Essex area
Paul Smith replied to mgtrees's topic in Employment
You have a PM -
I find the hand ascender is just another tool in the bag that comes out when needed, no use it stays in the bag. A lot of redirects and forks can be simply managed by pushing away from the fork. SRT is a great system but I think it's not for everybody!
-
Paul, I see a shinny impact block! Double whip tackle as well!
-
Where did you get the bobbin?
-
In the situation you mention Rupe you could try this. Hand ascender with a foot loop attached above the branch. Take the weight on the foot loop, as you stand up the unicender or rope RW will self tend as you have your lanyard over your shoulder. You could also use the pantin.
-
Craig, seems like a good answer. He was on a VT which afterwards he came down and adjusted by adding another coil.
-
Kev, he had a fall of about 6 foot before it stopped. Made is arse nip!
-
Perhaps I should mention a few months back a mate of mine had a fall of about 6 foot when a small branch hit the RW and sent him into free fall. He was lucky as there was a metal spiked fence below him. Made him think. Not 100% sure how it could have happened?
-
What's the black unicender? Not seen it?
-
Drew, nice job. Why didn't you fell it and what was the throw line doing doing up there? Did you get the throw bag stuck like I did today!!?
-
Good bit of kit! Worth having, never had my saw fall out
-
If a second climber needs to access the tree why can't he use is own line as normal? You could install an emergency access line if required. Can't see why you would access on one line then install another to work off though, line in get to work!
-
A spacer would still need to be tended though.
-
Great video with some nice editing!
-
There is no need to over complicate it. You only need to have a way of belaying from the ground. It does mean you need a long rope though!
-
Do you call MBS minimum, maximum breaking strain or even mean? There should be a set standard for terminology. All too often Kn and Kgs are cross referenced. Even rope diameters are in mm or inches!
-
My base anchor is tied of round a fig 8. The line goes up to the tip and back to the ground with a little to allow for any redirects etc. The fig 8 can be undone to allow the climber to be rescued. If the climber gets stuck in a crotch the options are the same as Ddrt.

The figures for 14mm from Yale are for the average breaking strain @ 6800kg divide by 7 = 971.4 . We should be working out the safety factor from the minimum breaking strain which Yale haven't given? I totally agree, to rig a 1 ton lump we probably haven't got any gear in arb to do it safely!
-
Hama, that's if you use the 5:1. I use it all the time with my GRCS.
-
You should use a 19mm dead eye if your using a 16mm pulley. You can always rig smaller but you can then go 16mm rope as well.
-
Practice more, don't concentrate on speed, make sure your safe and get a system going. Speed comes with confidence!

Alternative rigging pulleys
Paul Smith replied to Salix Tree & Countryside's topic in Rigging and roping
If you have 200kg hanging of the pulley you have 400kg of force on the pulley and subsequent anchor point. 200kg on the working end and 200kg on the other end to stop it falling. By adding more pulleys you spread the force which if you are doing any negative rigging is imperative. Take the 200kg example above. 1 metre free fall = 200kg X3 +1= 800kg. It doesn't take much to ramp it up! -
Like it!

What you editing it with?
