Minneapolis, MN, July 10, 2014 - The Minnesota Sports Facilities Authority (MSFA) and Mortenson Construction announced that testing has begun on the Terex CC6800 crawler crane at the new Multi-Purpose Stadium. Testing of the crane will consist of raising and lowering the boom several times over the next few days.
The CC6800 is one of the largest cranes in the world. When fully erect it will stand nearly 400 feet high. The crane will be able to lift up to 1,250 metric tons and has more than 1 million pounds counterweight. The CC6800 will be on the Stadium site for approximately 15 months.
"The introduction of the crane on the project signifies another major milestone for stadium construction," said Michele Kelm-Helgen, chair of the MSFA. "The stadium project is contracting with hundreds of Minnesota businesses and will employ thousands of Minnesotans. Two of the newest employees - veteran crane operators, managing the new CC6800 - are from Buffalo and Becker Minnesota."
The first and second pieces of steel that the crane will erect are part of the west end inner column. They weigh 280,000 pounds and 400,000 pounds respectively. The third piece of the roof structure the crane will place will place is the east inner column and is the heaviest load the crane will lift, at 450,000 pounds.
