During construction, the steel erectors required lifts that could be craned into the museum interior and be set up on elevated floor slabs. Floor loading was the primary concern as the workers needed to reach heights from 60' to 95' above each floor level to tie-in and connect steel support structure. Traditional rubber wheeled booms carried unacceptable weight and crane baskets were not considered an option.
The contractor was introduced to the Leo series and determined that a Leo 23GT and Leo 30T could both be utilized to accomplish all of the necessary construction tasks while meeting all maximum floor load requirements. With working heights of 75' and 98' respectively, the Leo's performed all expected tasks remarkably and were used extensively throughout the project.
