Rigging Kit Question

[NFG]

What NFG said:biggrin:.

 

Thanks, sounds like I got my sums right then...

 

Forgot to add, be aware the top pulley loading is 2x the weight (as in SRT top anchor), hence the need for a fairly large one - pulley that is

 

And the bottom strop for your bollard, perhaps a few metres of 20mm or similar size made up strop.

Fair play for the maths!

The 5000kg ratchet strap is that WLL or break point?

 

It will of course be set up in basket configuration around the tree doubling its strength. And the way the bollard is designed it will impart less force.... probably giving the RC3001 it's 3000kg WLL

 

 

 

I ask as we have 30kn slings that we use on a 300kg SWL

 

We also have 3ton slings which are 3000kg SWL

 

So it's important to know.

 

 

Good point about the ratchet strap.

I would say 5t MBS.

It would be interesting to know if any tests have been done on it when used in this application. I wonder what would fail first, the webbing or the mechanism?
