A storage box dangling from a skyscraper in San Francisco’s busy Financial District made for an unlikely sight over the weekend, especially considering the box contained an estimated 6 tons of steel.
The box was left hanging when the crane that was lifting it to the top of the former Bank of America building on California Street malfunctioned around 1 p.m. Sunday, according to San Francisco police.
The San Francisco Chronicle reported that the box was just five floors from the building’s roof when the crane failed, leaving it dangling 600 feet above the street, where alarmed bystanders watched from below.
The malfunction forced police to close six nearby streets to both pedestrian and vehicular traffic for approximately five hours while workers hand-cranked the box up to the roof at a rate of about one quarter-inch per crank, San Francisco police Lt. Mark Mahoney told the newspaper.
Police said streets in the area reopened around 7 p.m. Sunday.
