NEW YORK (CBSNewYork) – The FDNY is at a high-rise under construction in Midtown where a crane has collapsed.

The call came in around 2:30 p.m. Monday at the building on West 57th Street. The top of the crane, about 75-stories up, could be seen dangling down from the luxury building.

All residents of buildings on West 57th Street between Sixth and Seventh avenues have been ordered to move to lower floors. All others have been told to avoid the area.

There is no falling debris, but the Department of Buildings is on the scene. Emergency officials have also closed the westbound side of 57th Street between Sixth and Seventh avenues.

The site of the crane collapse is One57, a 1,004-foot tower that once completed, will be New York City’s tallest residential building.

All construction work in the city was suspended by the Department of Buildings at 5 p.m. Saturday in anticipation of high winds from Hurricane Sandy. Contractors and property owners were told to secure construction sites and buildings.

The Department of Buildings said Sunday that it had inspected all construction sites in the city.

So far, no word of any injuries.

i’m 40 minutes north of NYC in Westchester county, have watched this develop on TV and all i can say is pray hard...they said debris is falling from the building and they can’t do a thing about the crane until the storm passes....its effing creepy watching it on TV and reminds me of that terrible day 11 years ago in September- not in scope but in anxiety...

why didn’t they secure this crane or bring it down over the weekend??? gotta love those unions....

My Lord, as if they don’t have enough to deal with

“i’m 40 minutes north of NYC in Westchester county”

Any concerns in your area about the Indian Point nuclear plant? I understand it’s on the banks of the Hudson River and it appears to be in a bad location right now.

A perfect analogy of The Obama Campaign.........

I can’t believe this was left up there with days of warning. This incident and the ship that went down off the coast of North Carolina are shocking displays of total disregard of common sense.

[God luvs America]

have heard nothing whatsoever....its about 45 minutes straight west of me (i live in the eastern most part of the county)and if there was an issue or concern the evacuation would’ve been issued long ago...

[GeronL]

let me guess, they refused to work on a weekend?

[God luvs America]

they just made Bloomberg look like a bigger fool than we all know him to be- he was questioned about these cranes on Saturday and basically said “don’t worry- it’ll all be taken care of”...

btw- they said the dangling crane is directly over Carnagie Hall and is it breaks off its likely bye-bye Carnagie Hall...

These cranes are murderous at the best of times. It is a total hobbyhorse of mine that they are not secured better and everyone is tired of hearing me rave about the latest one. Now this one has hit a building full of extremely expensive condos. Maybe Mike-the-sugar-fat-and-salt freak will do something about it. Nah.

Having worked construction in NYC I can tell you it would have taken less than a day (overtime at that) to secure the boom of that crane. Not bring down the whole rig, just the boom could have been detached from the base and bought into the building or down to the street.

That crane looks like it could use some Enzyte.

tc God luvs America. My daughter also lives in Westchester County, I am keeping fingers crossed for their safety. They have a lot of trees on their property.

“Any concerns in your area about the Indian Point nuclear plant? I understand it’s on the banks of the Hudson River and it appears to be in a bad location right now.”

what would be the concerns? that the re-bar reinforced cement domed reactor would not take the winds? ain’t an issue; or that the Hudson River will rise forty or sixty feet due to 5-10 inches of rain - ain’t gonna happen

silly queastions derserve silly answers

In your informed opinion, what would be the most likely procedure(s) now for securing and lowering that damaged boom?

[jmacusa]

At this point there is a big problem in that the steel has been damaged and could collapse at any moment. The best hope would be to use steel cables to secure it somehow to the building, get a small ''lifting crane'' or derrick in place on the floor above where it's hanging and using cutting torches try to remove the damaged part of the boom and lower it down. This could have been avoided though and thats the damnable thing. There is a trade union, Operating Engineers&Riggers who install cranes and take them down, they do this work.. At the base of platform, where the bottom of the booms attaches are large bolts or ‘’pins’’ that secure the boom to the platform and the cables at the end of the boom (the wheel) are wound around a drum in the cab and much like a spool of thread, hydraulic gears run the drum forward and in reverse, rasing and lowering what ever it is the crane is lifting. Once the pins are removed and a ‘’guyline’ or guide line is attached to the boom to prevent it from swaying the operator simply runs the cable foward lowering the boom(hence the expression to ‘’lower the boom’’) slowly to the ground. It's how the crane is installed floor by floor in the construction process and how it's removed after. However, depending on the size of the crane and its weight, it's sometimes necessary to use a heavier ‘’lifting’’ or ‘’erecting crane’’ to do the job. This type of equipment is different than a ‘’derrick’’ which is a lighter type of machine. Judging from this crane it appears as if an experienced could have done the job in a few hours. I've seen done lots of times. It's not rocket science. The men who do this work are a union and they are very well paid by the hour, very well paid believe me.

[Hebrews 11:6]

Thanks for an insightful answer.

If you don't mind, perhaps you could answer further questions.

1. Without the big crane to lift it, how would they get "a small ''lifting crane'' or derrick in place on the floor above"? Elevator? Helicopter? Install a second crane?

2. How would they attach steel cables to the damaged boom? Crawl out onto it while wearing a safety harness?

Sounds like someone is gonna get really paid now!
