Lots of folks have rented something called a "Genie Lift" from a tool rental place. Some other folks have used pulleys in the ceiling.
My favoriate was a forum member used 4 chains. One chain per corner of the projector, ran the chains floor to ceiling. Lifted a corner a few inches, attached the chain. Went to the next corner. This way he was lifting only a few pounds at a time, and had the projector completely supported by the 3 other chains at all times. Took him about half an hour to get it up to the ceiling.
A Genie lift is safer & easiest IMO. Also remove the feet on the lift & turn them upside down, You'll gain extra height when raising the lift. Also get some dense foam and put it on the lift table so the projector can sit on it.
Besides cushioning, it will also provide extra height.
Have everything ready to bolt the projector into the mount. A person on each side on a ladder works great.
Took about 10 minutes to secure my unit to the ceiling. And I have vaulted ceilings.
Beer and 4 buddies is my best solution. Cheaper than a Genie and more fun. Just make sure that they drink after the projector is up.
The way I did it safely was to buy 4 cheap 2 step ladders (Rubbermaid makes ones that cost about $12 at Home Depot and hold 400 lbs each).
Line the ladders up at the corners, gently flip the projector and each take a corner. Hang the projector on the ceiling mount. That's it. Less than a minute and only 40 lbs per person. Even my wife and 13 year old boy could help.
If you are really cheap, you could return the ladders, but you wouldn't be able to use them later.
AJF The G70 mounts I buy from CHIEF have two pivot pins per side and are built like a tank. They weigh about 40 lbs for the mount. When the G70 is hanging over my head I appreciate the strength and extra pins of the mount.
