A large boom lift or a bucket truck. I'm assuming a building that tall inside would have ample room for one of the extended reach bucket trucks.

You can rent a JLG that will go up to 150 feet. No problem there. http://www.jlg.com/en-US/Model.html...otMenuId=d39badf6-70c2-4fa3-a03c-268cb1f085d7
As to hoisting the high bay, I'd either take a couple at a time up with me, or hook a beam anchor on the beam, hang a hoisting sheave or block, and have a groundhand hoist them up to you with a rope.

I'll agree with the 5k rated beaner....but have someone hoist them up?
An electric winch setup would be faster after the 3rd or 4th one.

Anything besides hoisting them up yourself, which could never happen. If you try to push or pull anything on the end of a 135' arm, you're going to move yourself probably 10 feet. A winch or a ground hand. Either way. I think most every boom lift has provisions for 120V in the basket (as long as you plug the bottom section in), so you'd have a place to plug in a winch if you wanted to. I was just thinking along the lines of simple.
Even the bounce up that high will soil one's delicates ~ ground man gets the hoisting work.

Isn't that a personal safety device? If so it shouldn't be used for hoisting. You should use one of these:

Only if I'm attached to it is it a personal safety device. If I'm using it for hoisting, it's a hoisting attachment thing-a-ma-bob. The manufacturer's information only gives a weight rating on the one in my post. They don't happen to place restrictions on what you may use it for. I'd use the one you pictured anyhow, mostly because that's the style I own. The one I pictured was only posted because that was the quickest picture I could snag. :wink: If it was bar joists, I'd be just as likely to hang the block off a small nylon sling or chain.

Compared to what? Compared to a regular 20 or 30 foot bay? I'd fully expect it to double the time to hang the fixtures, but I have nothing to base that on other than my gut feeling and doing the job in my mind's eye.

If it is safe enough for a 200# man, why would it be an issue for a highbay fixture?
Assuming of course, the beam is actually within arms reach of the fixture location.
In reality, one would probably just use a web sling tossed over the trusses and maybe a shackle.
I don't know that the beaner will get small enough to attach to the underside of a truss.

a bunch. i spent a year and a half in an edison large apparatus repair
facility, doing mostly high bay stuff.
i was fortunate enough to have a 100' marklift, which was a 6 wheel
boom.... this was in late 1980's and the JLG 100 footers were horrible.
i would not work in one. i've never cared for JLG products, but it seems
they have gotten better over time.
getting up to 85' took 7 minutes. getting down took 5 minutes, if you
didn't boom in. after the piping was in, you could put 3 fixtures in the
basket, and take them up....
an old timer once mentioned a rule of thumb for ladder work.... for
every 6 feet increase in work height from ladders, double the time
needed.
lift work is different, obviously, but here's a task i did at the 85' level,
and how it went.... 2000 amp nema 1 bus duct, went from MSG up
to the 85' level, 150' across two swimming pool size vacuum tanks set
in the floor, above a 500 ton bridge crane, and down to the 25'
level, then ran 200 yards, the length of the building.
out of the gear was fine, up the wall to 85' slowed a little, across the
"alligator pits" was ok, and then came the killer.... running the bus duct
downhill to the 25' level.... cause you have to suck the piece you are setting
up into the run..... it took two of us 2 days each to put those 6 pieces in. :-/
if i was running high bays in emt, and hanging lights that high, figure what
you would need to run them on an 8' stepladder, and then add a decimal
place. you're gonna have to pull wire that high as well... actually, your
high bay guy is gonna have to shove the wire, and then move, and pull
the wire out, make it up, move back to the first box, repeat, you get the
idea. it's gonna take a ton of time.

Marklift still a company? I like their scissors lifts. The whole deck can slide forward or backwards 4 or 5 feet with the press of a button with the wheels staying in the same spot. Kinda handy for working over a little bit of stuff.
The absolute worst I ever used was Hefty Herman. I hope they're out of business.

Safety equipment should never be used for both rigging and safety. Since it's designed as PPE it's likely that after someone loaded it during a rigging operation that someone will later use it for PPE. The two should never be interchanged. Those devices are typically never loaded when used as PPE unless there is an incident.

Cool. Then engrave it with "this is not PPE".
I agree PPE should never be used/interchanged for hoisting apparatus.

I agree with Markey, when I was working at the Seaport in Newark and when you were 100 feet up and the boom moved away from the pole we would just let go right away or you wouldnt be on the lift anymore. There is no way your gonna keep the lift from swaying, especially on a slightly breezy day.
