A Manitowoc 2250 crawler crane and a Grove GMK6250L all-terrain crane have been used to help construct a two-story underground parking structure at a mixed-use apartment complex at Minnesota in the US. The cranes were rented from Vic’s Crane and Heavy Haul by Hanson Structural Precast, the precast subcontractor working for general contractor Frana Companies. The two cranes lifted and placed the precast concrete wall panels and flooring sections. The heaviest load, an 18m double T floor section, weighed 29.
