Too big, and they suffer the same problem as all the other cranes you mention, they need a tower the full hight of the building they are working on.

You claim to be big on efficiency yet none of the cranes you site are right for the job. Why use a 70 tonne crane to lift a 2 tonne beam ?

Favco's building the Twins is not an arguement, it is a statment of fact.

Exactly my point...They use Manitowocs because they are enough strong to do work which has to be done there...Why would the use bigger cranes than is needed? No logic here...

No, no... As I said before, I think such skyscrapers construction should be divided into two stages:
1) construction of massive bottom part using powerful tower cranes like Liebherr 5000HC, no climbing cranes at this stage;
2) top part construction using climbing cranes like Favelle Favco (but I prefer JCC cranes, because of safety).

JCC cranes contain much more innovations than other ones. So, don't worry about effectiveness of Japanese cranes

Because of economical effectiveness... Manitowoc 18000 uses 447kW diesel engine, while 100t capacity Liebherr 4000 HC 100 power consumption is about 330kW. Also, as I said before, these cranes are more flexible and thus more fast at highrises construction works than crawlers ones.

But, OK it was just my meditations about effectiveness of steel skyscrapers construction...
But, life is life...

Looks like that site says the One WTC construction will be at the 20th floor in the 1st quarter of 2010

I believe that. The floor they are starting right now is 2 floors under the 20th.


I'm surprise that the concrete core will go up after the rest of the structure.

wow this week weather is not on their side. Showers almost each day plus Thursday is holiday.

From what I hear that cement block on Fulton street ( white square) is for tower crane.

Seems rather like an external elevator.

If memory serves that's how 7WTC was constructed.

WHHHHAAAAAAAA?????? Fitterman Hall is already completely gone????!! I was there last September 5th and it was still exactly like it had been on 9/12, about 20 stories tall, just with a black tarp around it. Now it looks like it's already been completely disassembled down to dirt. This is just a total shock. I never imagined that it would come down that fast.

I guess this is good news for the Deutsche Bank Building. Hopefully it'll only take a few months for it to come down as well.

After this many years, corruption, delays, accidents, loss of life, I would caution anyone regarding this project. Deutsche building is a mob project. It might be done by summer, or it might be here for another 5 years.

My advice, keep your expectations very low.

< Zen takes the 3 year old site construction plans and tosses them in a trash can on the corner of Broadway and Liberty >

Hey, they put a dual cab construction elevator on the crane base.
