Hurricane Milton's Winds Cause Crane Collapse at Florida's Tallest Residential Building Site

In St. Petersburg, Florida, a crane collapsed during Hurricane Milton, as warned by the mayor. The crane was part of a 46-storey condominium project, set to be the tallest residential tower on Florida's Gulf coast. Fortunately, no injuries were reported when it fell onto a nearby building housing the Tampa Bay Times.

The fallen crane left a hole in the building's corner, with twisted metal and debris scattered around. Another section of the crane obstructed the street below. The hurricane also damaged Tropicana Field's roof panels, where the Tampa Bay Rays play baseball. At the time of the incident, the newspaper office was unoccupied.

Crane Safety and Removal Challenges

City officials cordoned off several blocks to evaluate the damage and plan for removing the crane. The developer, Red Apple Group, confirmed that at least one crane cab fell and is collaborating with city authorities to address the situation. They did not respond to an inquiry from The Associated Press.

The 400 Central skyscraper is designed to reach 515 feet (157 metres) and will feature 301 condos priced at a minimum of USD 1 million, along with retail and office spaces. Removing the damaged crane may require another crane, similar to how construction crews use cranes to build others.

Tower cranes are typically used for skyscraper construction and can extend their towers as buildings rise. Crane safety involves balancing various weights and forces carefully. "When that cab operator shuts the crane off, he immediately releases the brakes and puts it into weather vane mode so it can move with the wind," explained Tom Barth from Barth Crane Inspections in Goose Creek, South Carolina.

Wind Resistance and Precautionary Measures

If a crane remains stationary, wind resistance increases like a hand in a river. Allowing the boom to turn reduces this resistance by letting wind blow alongside it. "Even on a seemingly calm day, you're going to see that boom move a little," noted Barth, who has decades of experience operating and inspecting cranes.

Cranes are generally designed to withstand winds of at least 100 mph (161 kph). In hurricane-prone areas like Florida, they often have higher wind resistance. However, there is a limit to what they can endure. Mayor Kenneth Welch advised residents near construction sites using cranes to evacuate, and police ensured threatened areas were cleared.

Removing cranes requires careful handling and can take days or longer, according to Barth. This timeframe is often unavailable once storm paths are predicted with certainty.
