NYC Crane safely secured, getting it down is next

Over the weekend, workers safely secured the NYC crane’s boom to the building, allowing nearby streets and building to reopen, after closing in fear of the 25,000 ton boom falling down to earth.

According to a  report from Engineering News-Record, emergency repair crews used a wrench on the tunrtable’s pinion gear, then hand-cranked the jib closer to the One57 building and used cables to secure the boom.

Nearby buildings and West 57th street opened up after being closed since Superstorm Sandy caused havoc on NYC and the crane positioned more than 70-stories above.

Now that the boom is secure, the questions is how are they going to get this broken crane down safely.

What will most likely happen is that another tower crane will have to be built to lower the other crane and damaged debris from the storm — a process that could take weeks.  

According to an article in Popular Mechanics, inspectors that visited the site cited wind as the primary factor for malfunction. Which poses the question: Why did this one fail and others in NYC did not?

Like construction expert Mr. Gogulski said in the previous post on the NYC Crane failure, there’s plenty of blame to go around, specifically on the general contractor for failing to recognize a need for additional tie-offs because of oncoming hurricane. So whether it being the crane operators fault or the project superintendents faults for not inspecting the crane for safety hazards before leaving the job site. Lend Lease, the construction company that runs the site, has stated it “took all recommended measures to position the crane in anticipation of a hurricane,” in Popular Mechanics magazine.

There’s been speculation of a strong wind force aided by an updraft coming from the building caused the crane to bend backward, but New York City has yet to conduct an investigation.

Terry McGettigan, a crane inspector told Popular Mechanics “It’s not going to be hard for the investigators to figure this out. You have to know the wind direction and the orientation of the crane, and that will tell the whole story.”
