‘Black box' may hold clue to crane's fall By By ROBIN ERB, Toldedo Blade
It was one of the first things investigators removed last week from the wreckage of the collapsed truss crane at the I-280 Maumee River Crossing project - a little black box.
The "programming logic controller" (PLC) on the 2-million-pound crane is "the brains of the whole operation," said Joe Rutherford, Ohio Department of Transportation spokesman.
As a result, investigators have told The Blade, it could hold critical clues to why the crane suddenly plummeted to the ground Feb. 16, killing four ironworkers and injuring four other workers.
Or it may not.
