The thing about the inside is that it is protected from wind. So you could use a cable with power, fiber, data etc all in one and just drop it in the middle with a grip at the top. No need for conduit that way. I had a custom cable molded for what I did. Cable went up and over a pulley so it was actually twice as long as you need.

Crane with a man basket for a day is $800, half a day is $400. The inside is pretty dirty, and I have no intention of going inside of it. I am planning to run shielded liquitite up the side. I don't want to put breakout boxes every 10-15' like I do on towers, so I'll probably run a steel cable with the wire attached through the conduit, to support the cable weight. So the trolley idea is for changing the light at the top, if required? That seems like it would work. The whole thing may turn out to exceed the cost of just going up on the commercial towers next to it.

You can lower it to work on the radios and use the cable to pull it back up. Then you only need to go up and attach the pulley one time. If there is no activity in the smokestack, you can run the cable up the inside. Depending on the diameter, you could build some kind of spider type of thing with spring loaded legs to span the inside and get pulled up too. Then it would be stealthy. I would love to work on this idea. I did a tower like this. Used one of those lighting fixtures common at major freeway interchanges. The whole lighting structure lowers on a trolly.

From there you are looking at a crane for $10K per day. Almost cheaper to get a helicopter at that point.

I think you are on the right track. Insurance and backups. Insurance should be cheap adding it to what you already have. Maybe a cheaper alternative if you want to be able to climb it are pegs and a safety climb. Pegs with epoxy would take about two minutes each, one every eighteen inches, a hard full days work. I did something similar using industrial sized concrete anchor screws on the face of a brick building years ago. I climbed it last Friday and it is still solid. I think the least effort would obviously be the lift but I have no idea how easy it is to get a lift that big, or expensive.

They are probably 300' tall. I can find a ton of examples of where companies have done this by searching 'smokestack cell tower' on Google Image search, but I have some real concerns. One concern, the stacks in this area seem to have been grandfathered in, as they have no warning lights on top. Two, we live in an earthquake zone. It is not a matter of 'if', but 'when'. So, these will likely come tumbling down. When that happens, are people going to point fingers at the company who added weight to the structure when it crushes someone? There are some obvious engineering hurdles (renting a crane every time there is an issue, or mounting low enough to rent a man lift, adding backup equipment in case of failure, etc.), but those can be overcome. I am primarily concerned about liability, and the potential for having to update the structure to include lighting. Has anyone on this list ever attempted something on the scale of a 300' smokestack from the turn of the century? Any pointers, or specific law firms that I should contact? Seriously debating just scrapping the idea.... -- If you only see yourself as part of the team but you don't see your team as part of yourself you have already failed as part of the team.
