An unusually warm, but blustery morning was the perfect backdrop for the placement of four heating/air conditioning units on the ASI Turning Center of Excellence’s rooftop. A crane extended 200 ft in the air picks up and places each unit in less than 4 minutes from lift to touch down. What also makes this lift unusual is ASI Turning Center of Excellence is across from Waukesha Airport so the airport needed to be alerted so aircrafts could be diverted during the lift.
