Manitowoc and Grove helped build parking structure
A Manitowoc 2250 crawler crane and a Grove GMK6250L all-terrain crane helped construct a two-story underground parking structure at a mixed-use apartment complex in Bloomington Minn. U.S.
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 a 60 ft “double T” floor section weighed 65 000 lbs. The load-bearing walls each weighed 38 000 lbs.
Tim Harty vice president of Vic’s Crane and Heavy Haul says the cranes worked well given the configuration of the job site.
“The 2250 was a great fit for our jobsite. Between the sandy ground and space constraints of the below-grade site we only had a small runway of space to assemble the crane. The crane had to be 105 ft from where we placed the concrete sections. As a result we needed a crane with ample reach and capacity.”
Vic’s first used the GMK6250L all-terrain crane to place the precast wall sections. The sections were taken directly from the trucks and placed into position as load-bearing walls. With the perimeter walls complete the Manitowoc 2250 crawler crane was used to place the heavier flooring slabs and the interior walls. To ensure the trucks could access the jobsite while keeping the crane on steady ground the 2250 was assembled with Series 3 counterweights and 210 ft of main boom.
The Grove GMK 6250L has a capacity of 250 USt and a full main boom of 236 ft. The Manitowoc 2250 has a capacity of 300 USt and up to 330 ft of main boom.
Both cranes remained on the jobsite for one month. The Grove 6250L will also return to work on the structural steel of the eight story apartment structure above the parking ramp. When complete the development called Genesee Apartments and Townhomes will include 212 apartment units 22 townhomes and 14 000 sq. ft. of retail and restaurant space.
