By GreenwichBoy, the B4 level is progressing nicely in the NE corner.

By GreenwichBoy, looks like formworks for the B3 level walls. Nice!

Two tower cranes installed at 2WTC construction are not TG1900 but TG2300B. Look at post #723 :

NYguy just posted a pic of it over at the SSP forum for T2.

230 Ton Maximum Lift Capacity, but load momentum is not so large. I don't know exactly, because long time ago I saw specification only for TG1900: as I remember about 4 metric tonnes at 60m. By the way, is there any body who has chart for TG2300B? So, please post it here. Thanks in advance!

It's bad that it took them so long to finaly start the construction. NY isn't NY without a World Trade Center complex.

thanks for the update!, these are the first clear photos of the cranes.

this also answers a previous question that I had regarding the fab/erection team. judging by those bannners, it is falcon/halmark.

looking for chart now

Look at http://www.sergiobetancourt.com/webs.../venetian.html

But 230t capacity is probably for very small working radius (I suppose to 5m) and short jib.

Here ( http://www.sergiobetancourt.com/webs...gcranes_04.jpg ) you can find capacity of 2300B at 13.72m radius and 48.77m of boom: 76 205 kg.

Also here is capacity at the same above parameters for TG1900 crane (one of such cranes started job at WTC3, but with new engine, winch and cab): 58 061kg.

Those will never even touch that max capacity, there aren't even enough sheaves on the boom head for the amount of line that requires, i wouldnt even know where they came up with 230tons
