Is this a good idea or what? --Labeling the arbor with the lineset number, so when at the loading gallery there's no confusion. Never seen this before, but it's something I'm going to try to propagate.
I have seen it done one place, what they did was paint the number on the sides of the bricks (big number over atleast a five brick tall span) that were dedicated to pipe weight. They also painted the number directly in front of the arbor on the railing so that you could see what number it was walking across and double check when you were infront of it.
Ours are labeled up at the grid, but I can't remember where exactly. It's really easy to tell what's what. It would be nice if it said "11 - First Electric" or something like that in case you forget the exact number, but still, it's handy.
everyday i realize how low of a bid we got on our instal, we have no line numbers up on the weight floor, or down on the lock rail also there are no numbers to speak of on the grid or on the pipes themselves. So we use index cards taped to the fly rail and wiggle ropes on the weight floor to show which one we are loading.
I like it too. During our install (8 years ago), only the rail was labelled. Last summer (six months after I started), we labelled the railing on the two loading galleries. Next month we're labelling all the batens. Progress, slowly but surely.
We label all arbors, locking rail, loading rail and batten ends on our installations. It only makes good sense and the miniscule cost in materials and time is far offset by client good will and our own time when we go back for inspections and maintenance.
