// Case Study
Unique three-lift stage system provides the customer the flexibility to extend an existing stage for performances, create alternate orchestra seating, or be used as material lifts for scenery changes – all with the push of a button.
Miller Performing Arts Center at Alfred University houses a 3,000-square-foot stage used for various theatrical and musical performances, but had no way of safely and effectively moving large pieces of scenery from a subterranean storage area up onto the stage and back again. The primary challenges in accomplishing this were the architectural requirements for creating a system of multi-purpose lifts for use in performances, and material movement between performances:
1. 150-pound-per-square-foot holding capacity (not lifting capacity)
2. This system had to be made up of three separate sections placed end to end, with one long side (facing the stage) being straight and the opposite long side (facing the audience) being curved
3. The three sections must be able to be operated individually or in unison
To satisfy all requirements as presented by the customer and their architect, two different models of scissors tables were selected that had adequate capacities to support the three stage sections. Because of the limited length and width of the outside two stage sections, especially with the special curved outside perimeter, a double pantograph solution was recommended because of its smaller overall “footprint.”
Each scissors lift was provided with its own hydraulic power unit, and a special motor control panel and operator pushbutton station was supplied to allow the operator to select any, or all, lifts to be operated at the same time.
The customer is completely satisfied with this unique lifting solution. Not only has the flexibility of the stage system been increased, but a safer means of moving scenery between elevations has been accomplished
