Breakaway lanyards

[softbankhawks]

It sounds like a tricky job. I use a very short lanyard with a positioner to be able to zip off the end at a moments notice.

Can you set a double whip low down on the anchor tree and lower into the loop?

How about a vertical speed line onto a bed of tyres?

Good luck!

The problem sounds like your main anchor will be pretty weak anyway, so your breakaway would have to be really weak.

exactly what i was thinking but couldnt word it. tricky one really, i would in that situation maybe hold onto your lanyard dont clip it in just hold it with one hand and cut with the other maybe?

Could you not fell it away from the building with a big winch and persuade the customer to move targets/accept collateral damage? (I imagine you have looked at this)

 

we have discussed the possibility of collateral damage...im just looking at ways to minimize that though

that would involve cutting one handed surely:sneaky2:

very much alive but with a significant lean on.

 

What size is the tree? can the main stem be supported in any way? I'm not saying to try and support its full weight, just some added extra security. What about ground anchors or tractors combined with a couple of tirfors for this purpose? I take it it's grass underfoot? you could have two ground anchors/tractors set apart adding extra support to the leaning beech.

 

However the angles are such that you wont be getting far enough out the limbs to do it without rigging.

 

Dont think of it as rigging, just rope controlled free fall, let the pieces run to the ground if possible.

 

 

It really is a job to describe, although i would say ive been doing this a few years now and this is the first tree thats made me do any real thinking for quite some time.

 

sounds as though you need to put extra time on it or the contractor your subbying to does.

How about a thin cable tie... could be quite strong though on second thoughts.

how about a caritool? i will try it out tomorrow

im not entirely understanding what you're getting at there......but the distance the tree is, and the height the rigging would need to be i think rule out any possibility of rigging....the pendular motion/angle just wouldnt work.

 

did consider a vertical speedline. There are a load of oak railings that would be in the way. We can take the rails off but cant do anything with the posts though. havent ruled it out though. i stood and looked at that tree for half an hour, and walked away with the opinion that anything i decided on at that point might change once i got in to the tree and saw it from a different perspective.

upside down wheelie bins will sort that, or traffic cones on top of the posts this'll stop them splitting in the event of direct impact
