Actually I dont know. I think the OP should have posted what he did on page 2. That link to it, I see now why it would use carbon links tubes, just
for a bit more malleability and maneuverability, probably has a string running through were you can pull the head and it will come up.
Or who knows, this thread make no sense. Even in that link I didnt find the specifications, but that thing does not reach to your knee, there no way
even if it was solid iron that it would be 200 something pounds. But whatever you know. Dont even know why the manufacturers would go carbon tubing
on long tunnel lines, seems excessive. But its probably just because they could charge more for it.
Some people would call that stupid, and maybe excessive, and if that thing cracked or the links broke, bet you somebody would be going "whos the
dingus who thought this would be a good idea?" But form the pictures it looks like the tubes are made of aluminum, why not make the whole thing like
that as well.
This whole thing makes no sense. But I shall be nice. I will just say it may have been a bit "over-engineered" Which is just a nice way of saying
maybe the makers wanted to charge a bit more for it from the companies who use such devices, and likely because they got money to burn.
And seeing carbon is in, and cool, even though it may work for cars, planes, bikes, and even long tubes/rope type lowering devices, I don't think it
would be best for lowering potential heavy and expensive piece of equipment down 98 meter holes. Not a matter of tensile strength, more like a matter
of dust getting in the carbon links, that or what if it gets stuck and you have to wiggle it around and dirt water, mud, gets in there. A little
crack in carbon and it will just spread, especially if its linked like that, aluminum or even rope or definitely steel, even though steel would be to
heavy, but you would have none of those problems.
Even thinking on this is headaches. The op, should have just given a better and that link in the opening post then on the second page. I thought
they just gave him that device, and left it up to him to figure out how to lower it down the hole, maybe even in digging that hole himself. Joking on
digging the hole, but not on the other.
Like I said none issue. Its totally "over-engineered" just like this thread is totally over thought on. They no doubt have warranties and such for
exactly such a thing. And no doubt the company that makes it expects it as well.
