In reply to Dan1898:
So in the session today I put forward your question. The answer confirms many replies above, and things to consider include: supervisor of the tower should be able to 'vet' that 'rigging' is done correctly. If only one person working the tower, that person should either have undergone a specific induction for that equipment or should be able to legally operate the climbing lines/ropes within the remits of CWA/SPA/MIA (!) training/assessment.
If you have any doubt whatsoever I would still contact relevant professional/legal bodies as obviously I don't know your full situation or context etc etc. The above is merely kindly intended advice! Good luck with it, they're quite fun to climb/instruct on.
