The slate from these high quarries was brought down the hill using overhead cableways. These had round-surface wire ropes, I would guess 50 or 60mm diameter and many hundreds of meters long.

The Coniston through trip from Levers water to Hospital level is very fine. Abseil through -pitches are 6m, 29m, 23m and 25m. You obviously have to be up to the SRT, but there’s no other difficulties.
