Stage technology or mechanics refer to mechanical devices used to move sets, performers, or other elements used in performances. Examples include overhead lifts, floor lifts, or turntables.
Automation allows the programming of functions that would be impossible with other methods. Larger and heavier set pieces can be moved individually or in groups with precision, repeatability, and even at high speeds. Accelerations, decelerations, and delays can be programmed, allowing devices to adjust their speed or trigger other devices upon reaching a certain point.
