I need to lift a 150-200 pound door panel to a 3rd story flat room. The only roof access is a ladder that is too small for the panel. 

Whatever we lift it with needs to be man-portable and small enough to make it up the ladder. I don't think dragging the door up the side of the building on a rope is a good idea. 

The roof cranes I've looked at are as big as the door and probably too heavy to haul up to the roof.

Any thoughts other than hiring a crane or a Lull?

I'd suggest a crane or a rotator tow truck as every other idea I have is heavy on the sketchy side.

See if there are any sign contractors in your area as they often have small truck mounted cranes for their work AKA " boom trucks".  We use them all the time to lift compressors, condensing units, small rooftop HVAC units and other equipment that's too big to fit through a roof hatch.  I would guess that $500 would cover you for a quick pick such as you're describing.

Genie makes a hand crank floor lift that will go 30'(Genie SLC30), it's portable-ish, and should be somewhere local for you to rent.  Lots of sheet metal/HVAC shops use them to get ductwork onto roofs without using a crane or man-lift.

That would work perfectly. I'll have to measure the building to make sure it will reach the roof but that should do the trick.  

Thanks!

So, we want to see this 200 lb door.

How about a Telehandler from someplace like Unites Rentals?

I looked into one of those first. Locally they want $600 for a day plus delivery. 

The door in question leads into the elevator penthouse on the roof of a building. They want a 14 gauge stiffened steel door. It will tip the scales at about 190 pounds.

I've rented boom lifts from HD, they have a 35' and 50' model.  I've used the 35' lift, which has a 500 lb weight limit to position several windows (one at a time) on the 2nd story of our house, and it's worked well for that purpose.  Not sure if that will work in your scenario.

Oh, hey! I used to design these! Pricey (over 2 grand) but really handy for roofers. For a single job, probably worth renting one or a competitor.

Gas or plug-in electric:

One of the last things I designed before leaving the company was a solar panel tilting carriage. It might work for your door.

Can you put the door in the elevator? :)

Did the old elevator machine room door have a recessed top edge and no roof overhang? Because that's a good way to have to replace one.

Buy a bucket truck with a blown head gasket from Craigslist.

Do your job, fix truck, sell for profit!

Dunno if this is even feasible, but it's an idea.

I wonder if that boom is PTO driven or if it's electric.

How cool would it be to remove the hood and use the boom to remove the engine?wink
