Moving Scenes Like Magic: The Gross-Funk Stage Trolley
In the world of professional theatre and live events, the magic often happens behind—and under—the scenery. When massive set pieces glide across a stage with pinpoint precision, there is a high-performance machine doing the heavy lifting. Enter the Gross-Funk Stage Trolley, the gold standard for radio-controlled stage automation.
Why Gross-Funk?
Traditional scene changes often require manual pushing or complex, fixed-track systems. Gross-Funk changes the game by offering wireless, automotive-grade platforms that provide:
- Omnidirectional Movement: With the Gross-Funk Mecanum Drive, scenery can move in any direction—sideways, diagonally, or turning on a dime—without needing a wide turning radius.
- Precision Control: Using a Dual-Drive system, operators can steer and drive with a single lever for incredibly sensitive movements.
- “Teach-In” Automation: You can “teach” the trolley a sequence during rehearsals. The system saves the route, speed, and stop positions, allowing you to repeat the exact choreography at the push of a button during every performance.
Safety First
On a dark stage filled with actors and expensive equipment, safety isn’t optional. Gross-Funk trolleys come equipped with:
- Stage-Edge Sensors: 4-sensor floor recognition that stops the trolley immediately if it nears the edge of the stage.
- Collision Protection: A flexible, circulating protection strip that triggers an emergency stop upon contact with any obstacle.
- Interference-Free Communication: Narrowband radio transmission ensures that your stage controls don’t interfere with wireless microphones or other show systems.
