[edit] Accident
On July 14, 1999 one of the most serious accidents with a heavylift crane occurred. Big Blue collapsed during the construction of the baseball stadium Miller Park in Milwaukee, Wisconsin, USA, with a load of 450 tons on the hook. Three people were killed. 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.[1]
