In the mining industry are the wire ropes used on winders etc fibre or steel core?. We use mainly fibre core but for some reason the managament have decided that it may worth our clients while to 'upgrade' to steel core?!.

Just curious really Graham. In 20+ years in the lift industry, i can count on one hand the amount of times i've come across a steel core main hoisting rope.

Would that really be an upgrade?
Fibre was supposed to allow freer movement in the outer elements IIRC............but then, perhaps I don't :confused:

IIRC fibre core ropes are slightly more flexible and retain the rope lubricant better, wire core has better flattening resistance for a comparable size and lay.

Edit: Seems to confirm flagging memory.

Most of the wire i use is 13mm fibre core as main hoisting ropes. Over speed governor is usually 6mm. Still at a complete lose to understand why all of sudden the ropes need changing....money making me thinks!. Can't belive i found that PDF interesting as well.

I do recall back in the ladder building days use of fibre cored wire was discouraged because moisture retained by the core would cause premature corrosion.

Always remember, nature is in charge, get it wrong and it is you who suffers!.

Dredging the old memory banks - I think that the failure of a fibre cored spreader was responsible for a serious (fatal?) fall on the Roof Tunnel pitch into Kingsdale Master Cave.

My recollection is that the person in question was unlifelined and his injuries were serious ('life changing' ?) but not fatal.

The pitch in question is about 5 m.

However, before anyone else says it, we're possibly getting off topic here.

I was told this tale when I ventured into making my own ladder, I used fibre cored wire mainly because that's what I had, however many cautioned against it for this very reason. Apparently the done thing is to treat it regularly with lanolin.

Things being what they are the most adventurous thing I've ever used the ladder for is climbing into the roof of the garage so I'm not too concerned.
