New York City has imposed stricter safety regulations for cranes following a two-year investigation into a Midtown collapse that injured several people in July 2023. The new requirements are part of an effort to prevent similar incidents from occurring in the future.
Under the revised rules, diesel-powered tower cranes must be equipped with fire suppression and detection systems. Additionally, operators and supervisors of these machines must meet more stringent experience qualifications, including having more than 3,000 hours of experience and certain industry certifications.
The investigation found that a fire broke out on the crane's deck, weakening the structure supporting its long boom. The report concluded that the fire started when flammable hydraulic fuel oil sprayed out of a disconnected hose near the engine compartment and came into contact with the hot surface on the deck. The operator was unable to put out the fire using the on-deck extinguisher, and the boom subsequently gave way.
The incident occurred during a construction project on 10th Avenue and West 40th Street, where 14,000 pounds of concrete were being lifted. Fortunately, no one was seriously injured, but several people did suffer injuries as the wire rope holding up the boom snapped. The crane's owner, New York Crane and Equipment Corp., had leased the machine to Cross Country Construction LLC for the job.
The Department of Buildings has issued four safety violations to the project's general contractor, Monadnock Construction Inc., and Cross Country. While one violation was dismissed, the other two are being challenged in court.
In a statement, Buildings Commissioner Jimmy Oddo described the crane collapse as "a singular nightmare scenario" but noted that construction injuries and incidents have decreased significantly due to rigorous enforcement of safety codes and regular reevaluations of those rules.
The investigation also analyzed similar collapses involving cranes from the same manufacturer, Favelle Favco, worldwide. The company had previously recommended measures to prevent crane fires and boom failures after similar incidents in Australia in 2012 and 2016. However, these recommendations were not being followed at the Midtown construction site.
As part of its efforts to improve safety, the Department of Buildings has created a new license class for operators of smaller hoisting machines, requiring them to have more than 3,000 hours of experience and certain industry certifications.
