Manhatton Crane Accident 3NEW YORK — A pedestrian was killed and three people were injured Friday when a huge construction crane collapsed in lower Manhattan as workers were trying to lower and secure it against rising winds.

The crane, with a 565-foot boom that stretched roughly as long as a city block, plummeted around 8:24 a.m. EST in New York City.  Twisted red-colored metal from the plunging boom smashed into parked cars and debris littered streets and sidewalks. 

Construction work was halted on the building Thursday after operators decided to lower and secure the crane against winds, which at times gusted between 20-25 mph.

“The report said they were in the process of securing the crane, actually preparing to bring it down, to be secured”

There likely would have been more victims if workmen hadn’t already cleared the area of traffic and people to prepare for lowering the crane. “It’s something of a miracle that there was not more of an impact.”

A few wind gusts of 20-25 mph were reported between 8 and 9 a.m. Friday in Manhattan, according to data from Weather Underground.

The equipment that collapsed is known as a crawler crane, which consists of an upper carriage, or boom, mounted on a crawler-type undercarriage that can be moved from one location to another. The boom is capable of hoisting 330 tons of weight.

The City Department of Buildings inspectors checked the crane Thursday morning, when workers installed an extension to the upper boom. 

The city issued orders for all crawler cranes across the city to be secured as investigators tried to determine the cause of Friday’s accident.  It has been the city’s first major crane collapse since 2008.

New York City Comptroller Scott Stringer said municipal building officials had failed to implement the many recommendations from a 2014 audit on construction crane safety.

  1. Check crane type and crane configuration.
    Get the crane Manuel and check the procedure for booming down. It may have required super lift counter weights to be attached. If they were required I do not believe they were attached.

  2. I think the problem is two ways either the operator didn’t follow the manufacturing load chart for securing the crane or the manufacture procedure for securing the crane against wind is not properly analyse by the manufacture.

  3. I have inspected cranes for years and have seen many neglected cranes both stationary and mobile.
    The cranes have factors of safety that are far too low for both strength and trip over stability.
    Also certification of the operators must be made mandatory everywhere.

    The SWL lift ratings should be reduced across the board to at least 50 percentage of their current values.

    Major tear down inspections should be yearly for major components not 10 years.

    Simply conduction stability tests yearly is not sufficient. There are many components in shear that cannot be properly inspected by simply visual inspections, if they fail a catastrophe will follow.

    Public safety must come first.

  4. Perhaps I am missing. Something in the photo, Close to 600 ft of boom, where are the counter weights?

  5. This serious accident sounds like the Big Bleu Crawler Crane Accident nevertheless they were busy to secure this crane due to the wind speed however the Big Bleu Crane Accident Root Cause was also wind speed….
    Saying that the following:
    Manufacturers Limit
    Every Make and Model of crane has its own limits set by the manufacturer based on the crane and its configuration. There may be limits for setup and for operation specified by the manufacturer. These limits should never be exceeded.
    Typical maximum in-service wind speeds
    – Tower cranes 20 m/s (45 mph / 72 kph)
    – Crawler cranes 14 m/s (31 mph / 50 kph)
    – Mobile cranes 9.8 m/s (22 mph / 35 kph)
    For specific limitations on the crane in use you should check with the manufacturer. Operational limitations may well be lower than these figures, eg when handling loads with a large wind area such as wide formwork panels.

    Maybe it’s advisable to check for weather conditions for the area for crane operations prior to set up the crane etc…..
