Bolts removed from a tower crane being disassembled may have led to a fatal crash at the University of Texas at Dallas, according to safety experts. The accident occurred at the $60-million Arts and Technology Building on July 7, killing two workers. Officials with the U.S. Occupational Safety and Health Administration are investigating.
Photos published in local news reports show the tower lying across the building that was under construction, with two tower sections separated. At the time of the collapse, the jib already had been removed from the crane, a Terex Peiner Model SK415, says one expert familiar with the accident who asked not to be identified.
