A Manitowoc 999 is at the center of a multimillion dollar expansion of the ACUITY insurance company headquarters in Sheboygan, Wisconsin. The 999 is lifting various materials that include precast concrete beams, columns and lintels. Additionally, the crane is lifting concrete buckets and steel beams. The heaviest loads weigh 11.75 USt and the highest lifts have risen to 80 ft. For this project, the crane was set up with 120 ft of main boom and a 150 ft luffing jib for a max tip height of 273 ft and a max lifting radius of 210 ft.
Dawes, a division of the ALL Family of Companies, chose the crane for its 275 USt capacity and extra-long reach. Dawes credited the crane’s 29,500 lb line pull and 440 ft 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 ft-tall flagpole, the tallest in the U.S.
