Abstract: On October 24, 2006, a crane crew consisting of the employee, five coworkers and the crane operator were moving a Kobelco CK2500-II crawler crane across a highway, while traffic was shut down in the evening. The employee and five coworkers, three on each track, were using the tracks of the crane as a conveyor, placing rubber mats on the back of tracks of the crane and removing the mats from the front and side of the tracks in order to lay the mats on the highway to protect the highway as the crane advanced. As the crane crossed the closed northbound lanes, from west to east, the crane operator had to swing the crane in order to prevent the boom from contacting a concrete bridge column. The alarms sounded as the crane began its swing. The employee, who was working along the southern track, was caught by the head between the track and the counterweight. The employee was killed.
