Big Blue Crane collapse
On July 14, 1999 at approximately 5:12 pm, the Big Blue collapsed during the construction of the Miller Park baseball stadium in Milwaukee, Wisconsin, with a load of over 450 tonnes (440 long tons; 500 short tons) on the hook. Three Iron Workers Local 8 members, Jeffrey Wischer, William DeGrave, and Jerome Starr, were killed when the suspended personnel platform in which they were observing the lift was hit by the falling crane. A camera crew was filming construction of the stadium on that day and captured the collapse on video as it occurred.
Wind speeds were between 20 to 21 miles per hour (32 to 34 km/h), with gusts of up to 26 to 27 miles per hour (42 to 43 km/h), at the time of the collapse. The boom was rated to 20 miles per hour (32 km/h), and other workers had expressed concern at the speed of the wind.
An investigation revealed that although the effects of side winds on the crane itself had been calculated, it had not been considered for the load the crane was lifting.
Aftermath and memorial
Three firms were fined a total of over US$500,000 as a result of the collapse. The widows of the workers, Marjorie DeGrave, Ramona Dulde-Starr and Patricia Wischer, settled a lawsuit against crane-maker Mitsubishi Heavy Industries of America for $57 million. Attorney Robert L. Habush represented two of the widows in their suit.
