Over the years, Wood’s Powr-Grip has supported many demanding architectural glass installations across major airports — including multiple air traffic control towers at Chicago O’Hare International Airport.

The 2008 North Tower project presented one of the most complex challenges ever encountered in tower construction. The structure’s dramatic reverse-angled glass façade required an entirely new approach to precision handling. To meet this demand, Wood’s Powr-Grip engineered the PT28 vacuum lifter. This unit was built specifically for this unique application.

Because of the steeply inclined glazing angles, standard lifting solutions were not sufficient. A custom counterbalance system was integrated with the PT28 to safely maneuver the oversized panels into position — maintaining both control and accuracy during installation.

The PT28’s success led to its continued use by Christopher Glass & Aluminum on the 2015 South Tower, where its power, precision, and reliability again proved essential to safely completing the complex, large-scale glazing.

From the North Tower (2008) to the South Tower (2015) and ongoing airport tower projects, Wood’s Powr-Grip equipment continues to lift the standards of architectural glass installation — ensuring performance, safety, and innovation take flight.
