This video shows the SERAPID lifts at the Dee & Charles Wyly Theater in Dallas. Stage Technologies worked with SERAPID to create a bespoke system for controlling the modular seating lifts that transport the seating up and down the ‘superfly’ tower.
The system uses ‘smart’ reversing starters to control a number of SERAPID Lift Systems and Turntables totalling 26 axes. There are two main lifts, one of which descends all the way to the building’s basement, where it collects the seating wagons; this is rumored to be one of the longest SERAPID lifts in the world, traveling 38 feet. Each of the six smaller lifts (three on either side) carries a three-position turntable. Each turntable has two ‘risers’, also equipped with SERAPID LinkLift Columns, that extend to form the tiered seating.
Safety needed to be of the highest priority and highly integrated throughout the building, requiring custom-written safety code from the Stage Technologies technicians. The Wyly installation is one of the first in the world to use ‘failsafe wireless’, which implements Siemens ProfiSAFE technology over a wireless connection to achieve emergency stop capability safely to Category 4 in accordance with EN 954-1, and SIL 3 in accordance with IEC 61508. These extra safety measures provided by Stage Technologies help to make the SERAPID Lift Systems in the Wyly some of the safest in the world.
Stage Technologies also provided development and modification of cutting-edge, wireless automation equipment - technology that allows a single operator to move the SERAPID Lift Systems at pre-set speeds from anywhere in the building where the Stage Technologies wireless signal is available.
