Self erector serves residential project
24 September 2020
Quasius Construction deployed a Potain Igo T 85 A self-erecting tower crane to build the 7 Penn Apartments complex in Wisconsin, USA, on a bustling street corner.
“Pennsylvania Avenue is a significant road for residents who want to access the lake or riverfront area, so it was essential to minimise public disruption as well as the additional project cost and downtime that road closures would entail,” said Matt Noordyk, director of field operations, Quasius Construction. “The Igo T 85 A gave us the small footprint, easy setup and long reach necessary for job site efficiency.”
Quasius used the 6.6 U.S. ton (6 tonne) capacity crane to build the apartment building from the ground up, including prefabricated walls, ceiling trusses, flooring, roofing materials and f-frame steel decks. The five-storey, multi-family apartment complex will provide 66 homes, along with 92 underground parking spaces and 8,100 square feet (750 square metres) of commercial space, helping to address the area’s housing needs.
The small size and constrained location of the job site would have required partial street shutdowns for a crawler or mobile crane to build the property. However, the Igo T 85 A was capable of reaching the entire job site from a single location while only needing a small base footprint, the company said. Also operating fully from electric motors, the Igo T 85 A self erecting crane’s quiet operation also proved advantageous for the residential project.
Quasius Construction positioned the Igo T 85 A on the west side of the building from where its 147.6 foot (45 metre) maximum jib radius covered the entire job site. The crane is operated via radio remote control, enabling improved job site communication and visibility across the site by the operator.
