Going in a slightly different direction than others have posted, have
you considered whether an elevated platform - a scissor lift - is
perhaps a better/more appropriate method of accessing this work than the
catwalk? While the catwalk may exist for certain types of maintenance
it sounds like the type of work you're doing requires a more stable,
enclosed platform, in a position closer to the beam where the
installation is being done, which a scissor lift can offer - especially
if there's a flat hard surface below like a stage. In that case the
issue of dropped tools, etc, may not be as much of a risk if the tools
can be held above the platform. Depending on what type of site this is,
they may either have a scissor lift already or would be familiar with
renting and using one in that environment.
Just a thought, and I realize not your primary question.
