A stunning performance
Rexroth technology plays a leading role on many stages.
Users were equally impressed by the performance and the high safety standards of these systems. Because a stage is not only “all the world” but also an enormously safety-critical workplace. Actors and stagehands are the only occupational groups that are allowed to work beneath suspended loads without safety equipment – falling flats could severely injure actors and workers. Consequently, sophisticated safety measures are actuated when a fault occurs, in order to prevent a fall. But a specially developed stage control system with intelligent software, together with special sensors, monitors the action to ensure that this cannot happen in the first place. The first version – the VTB 1000 – premiered in 1988 on the main stage “Grosses Haus” of the Staatstheater Stuttgart, and was refined over multiple generations down to today’s SYB 3.0.
For many years, Rexroth used primarily hydraulics in stage drives – but electromechanical solutions have increasingly been taking center stage over the past 15 years. Frequency converter technology had become so advanced that it represented a true alternative. As the technology leader in the stage sector, Rexroth rounded out its stage technology know-how in 2003 through acquisitions. The company became a single-source supplier, subsequently enabling it to win large-scale projects such as the new Oslo Opera, the National Grand Theatre in Beijing and the Bolshoi Theater in Moscow. The experts decide on a caseby-case basis whether a hydraulic, electromechanical or combined solution is best for each individual application. Today, Rexroth is not only an expert for the fabrication of movable stage machinery. It also supports the overall conceptualization and project planning of state-of-the-art theaters and opera houses with its decades of experience.
