hoisting pyramidal glass skylight 23 ft
 
I am having trouble finding competent person to do this..so thinking to do it myself. I can rent a skytrak with 45' boom, but would like to drop the skylight down rather than push it off the sides of a forklift that high up.

This requires me to hang it. It is 5'x5' square and about 3 ft to apex. If I get double eyed lifting straps on each corner and draw them together at the top, I could secure to forks with another strap...seems that would be a pretty good idea. Especially if I can secure the base with another strap to keep them from sliding down when not taut.

Or maybe slide wooden square 1x's and brace and lift that with the window tied down to them. I said 1x's because that is the space allowed by the pallet they are resting on now...but may not be stout enough...not sure about that. Could probably get 2x's in that space if I jack up the corners. Skylight weighs 240 lbs.

Anyway, thought somebody might have experience out there.

I have a sub-contractor who has a couple of boom trucks and anytime I need something lifted he makes it look easy. In addition to having the equipment and knowing how to use it he has years of experience. Find the companies that do that kind of work and talk to them.

Get it on to the roof, and 4 guys can carry it into place and make it look easy.
Have you spoken to the MFG of the window? They may have options or suggestions.

I failed to mention it sits on a stand alone 5'x5' cupola..so not accessible from roof that way. Closest thing to level is the deck that wraps around the 9'x10' tower another 16ft or so below the top of the roof framing. Good part is once the skylight is centered over that, should just slide into place on to curb just above the eaves.

Mfg totally signs off on this part. I did talk to a couple of installers 5 hours away. They suggested skytrak with personel basket attached, and 2'x6's extending from that. They didnt' have diagram and I had trouble picturing how they attached those to the basket. They said just strap them down...still not picturing that. The forks go into those baskets and do not extend out...if they did seems you could add extensions to those. But they don't.

I talked to the only rental place in the area. That's where most everybody goes for this sort of thing. They couldn't recommend even one contractor. Not encouraged by conversations I've had either. One guy had a 36' skytrak he just bought off somebody else. Not sure his level of expertise..but he thought tying to the bolts that attach the skylight to the curb was a good idea to hang the rigging...:surprise:

I still may use him, but want to make sure I have all the contingencies worked out first. The controls are not that much different from my tractor, but the height has me a bit wary.

A few picture would help us to visualize what your up against. From here it sounds like you need a crane or a lift.

I think we need pictures.

Sorry, no pix...

Skytrak is a boom lift, if that's what your mean by lift. Haven't run across any cranes locally.

Tie 2x6s to the forks with 2 ratchet strap on each.
Once you have the light loaded run ratchet straps from the 2x6 up the the rack above the forks, that will help support the 2x6s and stop the load from sliding forward.

Most of the truss installations on larger buildings or prefab wall assemblies will use a boom. Is there room next to this building for a big truck to set up. They are heavy and like solid level ground.

And get some pictures as mentioned of both the house and that skylight.

Look into the use of a Mini Tower Crane it will lower it in place.

Don't have a picture of one right now...not sure what you mean by the rack above the forks...would they be angled back towards the boom?

Also, I think we need a personnel basket over the forks. The skylight installers from Houston attached the 2x6's to the basket somehow. I guess boards could be rachet strapped to that, but would like a diagram of how that works.

Then it could just be guided instead of manhandled into place. Pulling 240lbs off the forks that high up on ladders seems unweildy to me. And there's no place to tie off the men. btw..I'm one of them..and I'm not a man...and 121lbs soaking wet. But I can steer it into position with just a strap, as could guy on the other side. I like that idea best if I could be assured of the sling setup. Just a matter of not crashing into anything...just center and lower it down, right?
