Link-Belt crane erects the only end-bolt steel structure in Boston
CAMBRIDGE, Mass. (March 2001) — A new building in downtown Cambridge, is the first building of its kind in the eastern part of the United States to incorporate an all-bolted structure instead of a welded moment frame to meet seismic code. A Link-Belt HC-238H II is being used to erect this “bolt only” end-plate moment project which, when completed, will house a high tech telecommunications research center.
Boston Steel Erectors, Inc. is erecting the four story, 200,000 sq. ft. structural steel building using Local 7 ironworkers. General Steel of Latham, N.Y. is fabricating the 1,600 tons of structural steel, which is about 30 percent heavier than normal because of the sensitive equipment and machines being placed within it. To hoist the heavier-than-usual steel Baldwin Crane and Equipment Corp. used a Link-Belt HC-238H II lattice boom truck crane.
The HC-238H II is working from 110 to 170 feet radius over the building. It was being used to lift and place steel members with weights up to 6,000 pounds. It worked down to a 50 degree-boom angle over the four-story building and up to a 78 degree-boom angle while shaking out the steel and picking up the loads from the storage area, which was about 50 feet away from the crane. Crane swings varied from 90 to 180 degrees.
