To keep on track with its project timeline, John W. Danforth Co. turned to Erickson Incorporated, a global provider of innovative aerial services, to place 44 sections of rooftop HVAC units securely in place in just one day. Erickson flew a Sikorsky S64 Aircrane helicopter above SolarCity’s 1.2-million-square-foot factory in Buffalo, NY. The Aircrane has a 25,000-pound lift capacity and easily carried the HVAC units—weighing between 14,000 and 18,000 pounds—in less than seven hours.
