A Manitowoc 999 is at the center of a multimillion dollar expansion of the Acuity insurance Co. headquarters in Sheboygan, Wis. The 999 is lifting various materials that include precast concrete beams, columns and lintels. Also, the crane is lifting concrete buckets and steel beams. The heaviest loads weigh 11.75 tons and the highest lifts have risen to 80 feet. For this project, the crane was set up with 120 feet of main boom and a 150-foot luffing jib for a maximum tip height of 273 feet and a maximum lifting radius of 210 feet.
Dawes, a division of the All Family of Companies, chose the crane for its 275-ton capacity and extra-long reach. Dawes credited the crane’s 29,500-pound line pull and 440 feet pm line speed with enabling the project to stay on schedule.
The headquarters expansion is not the first job that Dawes has overseen for Acuity. In 2014, the Milwaukee-based crane rental company employed a Manitowoc 16000 to erect a 400-foot-tall flagpole, the tallest in the United States.
