[OT] Risk adverseness and fear of heights

[Clive George]

Cable stayed doesn't have tension on the cables at the bank ends - the on a suspension bridge these need to be anchored in really very strongly.

They have acoustic sensors on the main cables of the Forth road bridge - ev ery so often they hear a ping as another of the strands in the cable breaks . Some time that bridge too will have to be replaced - unless someone think s of a good way to install a new main cable without removing the old one...

It also kind of reinforces the point about it being a PITA to do it with repeated hitching and unhitching etc.

They did look a bit feeble...

There was also far less climbing outside of the lift, and less of the getting round changes in diameter and style of mast etc.

[John Rumm]

IIRC they described the QUII bridge as a cable stayed suspension bridge.

Yes it is a PITA to do that .. but one slip;(..

On some masts a system called Rail-lok is used which means that you link your harness to a movable unit that can easily slide up along a sort of Installed "Rail" but if that should rapidly reverse direction then it locks up to prevent any fast downward movement;!..

On very tall structures such as TV Transmitter masts they will either be fitted with a lift or enclosed ladders or a cable stay lift will be used and all you have to do then is transit the cable lift "chair" to the mast in the area your working on. We once went some 600 odd feet up the mast at Mendelsham many years ago and it was a lot of effort just getting up there, let alone doing much of use whilst there;!..

The one I've got doesn't look that much but it IIRC is supposed to be

4000 KG capacity;!..

America bigger taller higher whatever else would it be?..
