How do the cranes recover their balance?

If the cable(s) were to snap when lifitng a piece of equipment near the weight limit of the crane what keeps the boom snapping back and falling over? How does the crane recover its balance quickly?

Nice compilation of photographs but some of them are mine and you do not have my permission nor have you purchased them form me so you need to take them out or take the youtube video down.

Looks like they started a new row of cladding on the southwestern side, where the black scaffolding has already been risen.. check the "1 WTC" cam of the KPI TV cams.. (http://www.video-monitoring.com/cons...itv/silver.htm)

Honestly guys if you can't handle people re-distributing your photos just don't put them on the internet. Hundreds (if not thousands) of people have probably already copied them to hard-drives, desktop wallpapers, sent them via email. You can't stop it. Even watermarks can be erased. Welcome to the 21st Century.

With the exception of tomorrow, it's suppose to be quite breezy/windy through Sunday:

NWS NYC Weather Forecast

Gusting to 20 mph at the moment. Winds are going to be stronger up at the top of 1WTC. I wonder what the wind limits are for picking the mast pieces?

Base Cladding

They are taking down all of the black safety netting on the south end of the base, so I assume base cladding is about to start in full force.

An article on this problem from Wikipedia:

Since the tracks were on the outer part of the bridge, passing trains caused the structure to tilt and sway. The wobble worsened as trains became longer and heavier. Eventually over years, when one train moved over the bridge one side would be lower than 3 feet than the other side. Something had to be done. In 1956 at a cost of 30 million dollars a repair program was begun. Still, during these repairs trains could still cross the bridge, but many times one of the tracks had to be closed with both travel lanes reduced to one track, further restricting the number and size of the trains crossing. [10]

Even with the 1956 repairs the New York City Department of Transportation had failed to maintain the bridge properly and beginning in April 1986 a major repair program began and because of the large scale scope of these repairs there was blocking of the paths of trains that crossed the bridge and reduction in the number of trains passing between Manhattan and Brooklyn. The north tracks, which had been more heavily used, were closed first. This blockage split the B and D trains into two sections (trains from The Bronx and upper Manhattan terminated at 34th Street – Herald Square, thus suspending express service on Sixth Avenue while trains from Brooklyn section were rerouted to Broadway via express and the south side of the bridge) and rerouted the N via the Montague Street Tunnel.

The north tracks were reopened and the south tracks were closed simultaneously in December 1988, merging again the B and D trains, rerouting the Q to 6th Avenue, and suspending express service on the Broadway Line. After an 18-month delay of procurements, the New York City Transit Authority and politicians pressured the DOT to resume N train service on the bridge's south side on September 30, 1990, despite warnings from engineers that the structure was unsafe and major repairs still had to be made.[11][12] On December 27, state inspectors forced south side service to be rerouted via the tunnel again after discovery of corroded support beams and missing steel plates.[11] Following the controversial firing of the city's deputy commissioner for bridges, David Steinberger and his administrative assistant David Bronstein by Transportation Commissioner Lucius Riccio after this closing, the New York City Council's Transportation committee held an inquiry into the decision to restore subway service on the Manhattan Bridge south side (as well as the safety of all New York City bridges) with reluctance from Riccio and Mayor David Dinkins.[12][13][14][15] They found that the Transportation Department and Transit Authority's lack of cooperative inspection were a major contributor for the deteriorating conditions.[16][17][18]


It's really scary to think about what Sandy would have done to the Manhattan Bridge had it occured thirty years ago!

On the bottom of the SE corner of the base, you can see some metal frames that might have been put up recently.
