A few from work : 12-07-06

Forgot about these; I had an after-midnight service call swapping out some projectors mounted atop an elevator car at Rockefeller Center (er, Plaza)...might be of interest.


To service these little A/V systems on the elevators, an elevator tech has to bring it to the 67th floor where the observation deck is and "bump" it down a bit so I can climb on top. the doors are wedged open. It's even trickier than it looks: the roof of the elevator is glass, and I have to step carefully on the framework above. Not dangerous- there's no room to fall between the car and the shaft.  As for the car moving, I trust these  guys from Schindler, but I never linger for more than a second with part of my body inside and another part outside. And I'm careful not to drop anything, since I lost a brand-new LED flashlight the first time I worked on one of these. I asked the tech if we could go look at the bottom of the shaft for it, and he laughed. It's 700 feet, onto concrete, after all.
These projectors are nice, but they are not supposed to be operated at an angle exceeding 15 degrees... you see here why they fail so often.  Using mirrors was not an option in this install, so here they are, pointing straight down. Lack of proper ventilation causes the panels to burn up and turn purple, although sometimes they show other symptoms.
Oddly enough, the day after I did this work, one panel of glass on this car shattered mysteriously... something must have fallen from the shaft when the car was way downstairs- there was a good-sized ding  at the center of the web of cracks. But it's safely glass, laminated, so nobody got hurt.
And it wasn't me... honest!!  I'm usually picking up loose junk up there, not leaving it lying around!!

There's an indoor observation area; here's a look out the window. It was a fine clear night, but the wind was so intense. I didn't dare go outside (not that I'm really supposed to; Security might not like that too much).

Looking south, through the glass... pretty good night shot for my camera.

Got to get on the deck sometime during the day with my camera... best view in NYC, if you ask me... the Empire State Bldg view is cool, too, but from 30 Rock, you can see the ESB. ;)

Some good shots there, and a nice explanation of what you do other than come onto the V and share your expierences!  ;D

Great shots!

A worthy question...  ;D
The "Top of the Rock" is the roof of The RCA Building- er, no, now it's the GE building , the tallest in the  Rockefeller Plaza complex. When tourists visit, after being herded through the retail shop, they pass through a whole "experience" on the mezzanine level, with a neat little museum, a theater where they watch a brief documentary on 3 huge screens, and the "Beam Walk" (another of my tasks is maintaining those projectors). Then they hop on an express elevator (one of 4) that shoots them up 66 floors to the observation area. It takes about a minute or so, so they decided when they re-opened the roof deck to add a little audiovisual experience. The company I now work for installed this stuff a couple of years ago, and now has the service contract for all of it.

The glass ceiling of each car is made of  special glass that turns milky white when a charge is applied. When you first step in, it's white, with white lights above it. As the elevator starts to move, it goes clear and the lights go out, revealing the shaft, which has some nifty colored strobes and things all up its length. Then the projectors kick on, and there's a sort of abstract history montage, with sound provided by little speakers inside the elevator. The amps and projectors are mounted on the cars, and audio and video are fed via thousands of feet of fiber from mpeg servers in a rack in the theater area on the mezzanine. When you stop at the top, it "turns back" into a normal elevator. Neat trick, and it doesn't always work right. ;)

Ther are some pictures of some of this stuff on the website; see the "About the Top" page... it's a pretty cool thing to do when visiting NYC, and the view from up there is stupendous.  :)

I was wondering that as well... forgot to ask though! Neat, however it seems a little impractical!

Cheers, Gunny

It's ridiculous, considering that it just kills these projectors being mounted vertically like that...  :'(

And I've ridden these cars (inside) during the tours... most people are just starting to look up and go "huh?" when it's over. Silly. I think the view up the shaft is entertaining enough... zipping upward at 700 fpm; pretty cool.
