So I'm retiring my CRT projector which I love but it's time to go 1080p with an anamorphic lens. Now the challenge is, how the heck do I take down a 100lb projector from a ceiling mount that's at least 8 feet up? I'm curious to hear of any innovative techniques outside of 3 or 4 of your close friends or some fancy construction equipment.

Unbolt projector from mount, gravity will take care of the rest :)

I have a tall shelf in the same room that I used to set the pj on first, then a shorter one and finally a table about 32" tall. Unhooked it from the mount, set it on the tall one. Moved the next sized shelf next to it and then moved the pj down to that one. Moved the big shelf out of the way and moved the table next to the pj. Moved the pj down to the table. My girlfriend and I managed this very easily by moving it in small steps like that. The pj was a vph-1000 so it didnt weigh as much as the 1272 that took it's place.

You should be able to do the reverse of some of the creative lifting procedures that people have used over the years. I've seen mention of chains, ropes and threaded rods...read some old messages here, I'm sure you'll find something that works for you.

Zamboniman told me about the the threaded rod technique. Replace each short ones with long ones one by one.

No, you use long ones that reach to the floor, then just spin down some nuts to lower it.

Helmsman, a lot of the techniques involve hanging things from the ceiling, and that depends on what kind of hanging-from-ceiling options you have. Ratchet straps can work very well, or ropes or chains. If you don't have a good way to attach something to the ceiling, then you're probably limited to floor-based approaches.

Offer it free to whomever will remove it...

Hmm, the threaded rod technique spinning the nuts down to lower it is an interesting idea. I really don't want to damage the ceiling using something hanging from the ceiling.

And then of course I could just leave it there.

Yeah,

What do you have and where are you located; I'm sure we can find somebody to take it down. :D

Heh heh... that sounds vaguely familiar... ;)

(... after Sonynut and I wrestled my 1272 off my cathedral ceiling this past Saturday.)

Ask another person to help you? Removing a projector from the ceiling is extremely easy with two people as long as your mount is well-planned. For me, I just unscrew everything and lift it off the unistrut, one person on each side.

Leave it in place. You'll need it during the downtime of your digital..:)

rent drywall lift from home depot. amazingly easy this way. This is what CRT installers used in my area.

There is really no substitute for brute force. Me and someone else my size can have my projector down in about 30 seconds. It would take longer to remove the mount because I would have to run the nuts off of the long threaded rod pieces. Just taking the projector down or putting it back up is simple though, now that the mount is there.

One hundred lbs is one small CRT. Two friends plus you would be real simple. One friend on a step ladder on either side. You in the middle under the projector to help with the weight. they each unhook it from the ceiling part of the mount and walk it down the ladders you holding some of the weight.


Curt. I know many who have a digital to back up their CRT but no one the other way around.

I think Curt has a thing about digitals being unreliable. Odd for somebody who makes a living fixing CRTs, but there you go. ;)

I love CRT PJs, but I have to say that I've never had a digital go bad personally. And in my line of work, that means putting them on motion platforms that shake the bejesus out of them, fling them all over... they're hanging around in a machine shop getting beat to hell... I've got one that I've taken apart and put together more times than I can count, and it's still going after four years of abuse. I can't kill the things. I've shipped 40 of my motion systems with digital PJs on board in the last 2.5 years and have had one outright failure and one bulb go among four or five different brands.

So, at least among ~$1000 digital projectors, reliability doesn't seem to be an issue.

Bang on. 2 step ladders, 2 friends and 2 nice bottles of wine did the trick. What helped was a bracket on the mount that allow you to loosed a couple of nuts and then slide it off when we were ready to take it down. 3rd man in the middle and underneath to take the weight and make it easier for the other 2 to come down the step ladders made it a suprisingly simple exercise. Thanks for all the posts. AVS is great!
