USA - Hoists manufactured by Vortek, a Division of Daktronics, are centre stage in the Dee and Charles Wyly Theatre at the Dallas Centre for the Performing Arts. The custom hoists manipulate seating sections along with Vortek Pro Series hoists in an advanced fly system. This innovative theatre design was commissioned by REX/OMA, Joshua Prince-Ramus and Rem Koolhaas.

The theatre consultant, Michael Nishball, of Theatre Projects Consulting said, "When direct lift, multipart-line in a high capacity hoist is required, there is no group with as much experience as the Vortek team at Daktronics. At this point, it's clear to me that this is going to be a very successful power flying and controls installation."

Scheduled for completion in October 2009, this 74,915sq.ft facility has 12 stories and seats approximately 600 people. The vertically stacked floors are unlike the traditional form of theatres. It places support spaces above and below the auditorium, providing maximum flexibility of performance space.

Without the Vortek custom hoists, this design would not be possible. The hoists have the capacity to raise sections of box seats and balcony seats allowing multiple configurations for the various venues.

"Taking the vision of the theatre consultant and architect of literally hanging the seating from the upper floors was an enormous engineering challenge. A lot of credit goes to Vortek's engineers and field technicians; the towers flew the first time the button was pushed," said Steve Hagen from Secoa, Vortek's authorised dealer. "The general contractor, McCarthy Building Companiesassembled a team that looked out for the owners' best interest and all of the subcontractors, along with the logistics of this one-of-a-kind building."

There are 51 hoists installed in the entire project, of which 45 Vortek Pro Series hoists and two custom hoists are installed on stage to control curtains and scenery. However, the real measure of innovation lies in the four custom hoists used for shifting the seating towers. Vortek engineers were handed the challenge at the onset of the project two years ago to develop these four massive, custom hoists. Each is capable of moving horizontally and vertically with the lifting capacity of 60,000 pounds.
