Replacement of extremely bulky Finn glass panes in Chicago
At the 155 North Wacker high-rise building in Chicago (USA), Heavydrive replaced five extremely bulky and heavy glass fins. The task was accomplished using VSG 2000 KL 9 MH suction system for Finn panes. With a suction length of nine metres, the vacuum suction system is the ideal solution for installing glass fins weighing up to 2,000 kilograms. The additional attachment arms mean the suction length can be extended even further.
In Chicago, this was used to replace three glass fins 0.80 metres (2' 8") wide and 10.4 metres (34' 8 3/16") long, as well as two Finn glass panes 0.8 metres (2' 8") wide and 12.9 metres (43' 6 7/16") long. The glass elements, weighing up to 1,814 kilograms (4,000 lbs), were installed quite simply via radio remote control and the glass replacement was carried out safely and on time.
