LOL! No, Vne speed is a bit more serious than that... Aircraft have come apart just 5 to 10 knots over Vne before. It is a serious limit developed from lots and lots and lots of testing.

So, what did you think of my pics? :D

thats just because they dont have Scotty ;)

But I don't know everything. I keep up on alot of industry news also, and I've never heard of it being done. I have 8 acres of dirt to drive around on and for $5,000.00, I'll use it.

My biggest concern is the safety of my crew. I have been asked to decide on the validity of this person's judgement in general and any contributions he may make to my company in the future. I am hesitant to trust a person who has such big stories all the time and doesn't seem to have other basic skills for completing simpler tasks with any amount of effeciency. (sp?) I am giving him the benefit of the doubt to try and be as open minded as I am at this point, but my trade is so full of big stories and little experience, that I have to wonder at times. Hmmmm...

OSHA regulation preclude the use of a safety facter of weight x 3, which I will excede. The question is really not whether we might do this lift on this project, but whether it is feasible for a future situation, and whether this person is trustworthy also. That's my job.


If a conventional crane can't be used to set an object on top of a building because of distance or height concerns, a tower crane can be erected in an elevator shaft. The crane can be as high as you want it to be, that is how skyscrapers are built. As the building goes up you simply raise the crane on its own tower a couple of more floors. These are called self erecting cranes. The boom can be as long as you want, within reason, and is compensated on the other end with counterweights.

I am aware of conventional cranes that have a maximum capacity of 500 tons. The rental fee on cranes of this sort is enormous, though. They have to be transported in pieces to the jobsite and assembled there. After assembly they must be certified by a state licensed inspector. The ground they sit and move around on has to be sampled, tested and certified to be capable of supporting the crane and its load. It all becomes very costly.

<-----------Has maintained, repaired, assembled, erected and operated cranes up to Manitowoc 200 ton crawler with 200 foot latticework boom. Making a blind lift is the scariest thing a crane operator ever has to do. The only thing you have to go by is the person on the other end of the radio telling you to swing, boom up or down, raise or lower by so many feet or inches.

ROTFL! :)

Thanks! That was one of the most fun jobs I've had in awhile. I don't have a ton of experience doing that, but I hope to get more soon.

FYI, those are contract jobs, you're paid by the job. I was paid $500 for that job!!! :)

found the pictures

http://zzz.com.ru/pic133-1.jpg
- A US Army CH-47 chinook carrying a bus - note how much bigger than the bus the chopper is. This is to demonstrate the size of the next picture:

http://zzz.com.ru/pic133-2.jpg
- A Russian MI-26 helicopter carrying a damaged CH-47. This thing is huge

http://zzz.com.ru/pic133-3.jpg
- Gigantic. I believe the tail rotor blades are longer than those of the main rotors on most other helicopters. Something like 8m.

impressive ;)

Those pics are impressive Czar, thanks for finding them... Yea, that middle pic shows the size all right... The CH-47 is longer than the S-58T that I flew...

Where abouts are you located? Back in '97 or '98 I watched a Sikorsky in Brea, CA placing what I thought was an A/C unit similar to your pictures... It was quite fascinating to watch... I had quite an interest in helo's in my younger days, having taken and passing the US Military FAST test, but wound up in the Rangers instead... Never pursued it after that...

As a side note, an overloaded soviet MI 26 carrying some 118 people in Chechnya was shot down by a SAM, killing I think all aboard.

The Army Rangers are an impressive bunch, I'm impressed! :p

Yes, and the Russian Government was quick to blame their own people for the debacle.

Impressive that they can get 118 people on that thing, it really is nearly the size of a 727, isn't it? :)

Further proof that if you have enough money, you can make anything hover... :D

*hmm, picturing a 747 with rotors on top*
