Cheers John, In South Africa on the gold mines, some shafts had a Marry Ann cage, don't know why it was called that, but it was a smaller cage for mine officials to travel in while material/supplies were being moved in the larger cages. I was just wondering today if Boulby adopted the UK mines styles of cages or the South African cages, sounds like a little of both! The only thing is, UK law forbids traveling in a cage when materials or minerals are being transported, technically we weren't allowed to take a tool bag of tools in a cage during manriding, but a blind eye was always turned. I think some pits adhered to the no tools in a cage with men, had to be sent after manriding....Expensive tools...LOL
I know we sometimes "bent" the rules, depended on the winding engineman, Onsetter and Banksman, but I've ridden on the bottom manriding deck of a skip when it's full of minerals... At man riding speed of course, I've known of officials riding on tubs full of coal at coaling speed....
I'll bet we have more than one member who has ridden with minerals in a shaft, like everything else, you tried not to get caught...

Just a snippet of information about the old No1 tower, when built, it was built as a free standing tower same as the No2 tower. No idea when they added the forestays, but well after my time. My guess is they were added due to major stress cracks in the concrete, and too prevent them getting too bad before headtower replacement. There was also a heavy reinforcing collar cast around the tower if you check photos before the tower was replaced, probably at the same time the stays were added.
Having been at the tipping level many times when I was central electrician, I can attest to the fact the tower moved during winding initiate and tipping. I'm no structural engineer, but my guess is if they had incorporated stays during construction, the tower would have had a much longer life.
