That's what I suggested to groundie, but he wasnae keen!

There comes a time when lateral distance traveled demands a wire rope mainline, with a trolley, then a rope haulback line, for controlled descent and retrieval of the trolley.

 

Too much stretch's most definitely a limiting factor for serious payloads IME.

Put him in it to test it may be he will change his mind.

Now that sounds like fun.

 

With the stretch issue in mind, I assume I'd be better to rig the line using an old climbing (Static) rope, rather than a lowering (dynamic) rope. Is that correct?

Put the cost of some half inch dyneema high molecular weight synthetic winch line on the job IMO.

 

Light as a feather, floats on water, very low stretch ratio.

 

But somewhat pricey.

 

I'm an old steel lover meself!

So, as I was saying, an old bit of climbing rope'd be better than my rigging rope.

 

How much?!!? how do they get rope with a gold core to float!
