Remove Weight To Make Something Better
You would think, that by now, we’ve pushed the technology in lifts, as far as we safely can.
But, go up in a very tall building and you’ll often have to change lifts to get to the top.
One of the problems was that the weight of the steel cable that holds the lift car up, was just too much.
But now Kone have come up with a carbon fibre lift cable, that is both light and strong. They call it Ultrarope and it’s described here on their web site.
They claim that maximum lift heights can rise from 500m to a kilometre, whilst saving energy too.
That sounds good to me.
It’s a classic case of improving something, by using a new lighter and stronger material.
