Not sure that person in bucket could do much..two on the sides would tho..especially if they have straps attached to the sling on both sides.
I would just use the forks and have it holding over the cupola before they went up the ladders to position while it is set down. It will have to come in angle right, with 4 straps they won't be turning it much.

Once you have it sitting on corner blocks you could change to the basket for the men.

Corner block are top set on the curb so you can get the 2x4 out of the way.
The want to be thicker than the 2x4s

Do the cross pieces at the 45's serve any other purpose than to keep it together? would they be able to help with the rigging in some way? How long should they be?

i was wondering about screws with wing nuts so easy to undo..does that make any sense...?? Or make me a wingnut?

Nothing wrong with a little over kill, you want more than one in each spot so the whole thing can't rack out of shape. If those blocks are under the 2x4 then you should be able to sling to them.

Did you say wing nuts were ok?I was planning to do two opposite sides quick release if the wing nuts work..with 4 screws per corner? I could do regular screw on other sides since they don't really need to be unscrewed to have the pieces fall away.

They won't fall away you will have to pull them out from under the light when it it sitting above the curb.

If each 2x4 has one block screwed with 4 screws and the block at the other end had one wing nut, that should work, but you would have to get the bolt out too.

I think it would be just as easy to have 2 screws at every joint screwed from below and you just take drill driver up with you and pull the screws the blocks fall away and you slide out the 2x4s

Ok...that makes sense. The cross piece would be UNDER the frame, right? I am also thinking the straps with the eyes should circle the cross piece instead of around the corners. There is plenty of room for that. I put a 34" 2x4 up to it and looks like the straps could pass thru the loop on the end of strap encircle the crosspiece and be brought up at the top...all four sides would have straps center of the skylight. Nothing would touch. I might have to do some ties to keep it from slipping. Anyway..how does that sound?

That sounds good, the big trick will be driving in at the right angle to be close enough to safely set it down, you don't really want anyone on a ladder until you have it down

I don't think there is anyway but straight forward to approach it. isn't there a swivel type thing where the rigging meets the straps off the fork that might work for that problem? I saw somewhere a swivel hook.

That's also where I think leashes off the sides would come in handy. Person even on the deck could probably turn the unit, certainly off the upper side ladder where they would be closer to the landing site. That ladder is on a cricket, so shorter than the other side and closer to the docking site.

The easiest swivel if you have room to put a cable come a long between the forks and the slings, cable around the forks with the come along hanging up side down, it's top hook swivels, and the cable will allow some turning.

Would that do away with the need for a cross board on the forks?

steel on steel can be slippery and forks can cut cable when slipping happens.

Apparently timberlox not the way to tie the cross piece to the frame? I'm splitting them..or should it be treated 2x's? Or predrilled? I had the timberlox on hand, but maybe they have too big shanks? 3/8 x 4 I think.
