Since 1987 Haag Engineering Co. has been compiling data and information relative to causes of crane accidents. Following presentations to OSHA and the American Insurance Association in 2009 in Washington, D.C. Haag embarked on a full-scale compilation of the data to evaluate causes and potential trends of accidents that could be used to improve crane safety. In 2011 Haag was joined by MIT, in conjunction with a graduate research program, to produce an unprecedented crane study of over 400 crane accidents which is scheduled to be published in June 2012. Software is being produced during the current study that will allow Haag to update annual findings in order to identify in part the effectiveness of training and the certification process, as well as identifying potentially dangerous trends in the industry.
