I don't think there's any limit. I've seen steeplejacks working on ladders
at 400ft.

Steeplejacks ladders are very different to your average "lean against
the wall" class of ladder being bolted[1] to the thing you are climbing.

[1] I say bolted, but don't actually know how they fixed their ladders/


Usually they have "hook" type attachments built into the structure they
hook the upper part of the ladder onto then tie them together as they go
higher..

Well thats what Fred Dibnah did when he did the Gasworks chimney in
Cambridge..
