Safety installations: stage safety engineering technology

Bosch Rexroth stage safety with hydraulics

In the area of the overhead machinery, devices such as smoke outlets, smoke vents and fire curtains form the basis of active safety in opera houses, theaters and convention centers.


To prevent the occurrence of overpressure in the stage area, safety engineering technology such as technical fire safety devices are installed to eliminate smoke quickly if necessary. Reliable and simple operation is ensured by independence from the mains electricity supply, typically through the use of hydraulic cylinder drives.

It is customary practice nowadays to operate stage safety devices hydraulically or by combining an electric drive with a hydraulic brake, because these designs most reliably comply with the technical safety requirements.
