Increased safety for stage engineering equipment

The use of increasingly powerful drives has resulted in intensive safety-related discussions in the field of stage technology. Comprehensive tests and simulations provide important results during the measurement of load peaks for various emergency stop scenarios. Rexroth offers solutions for hydraulic and electromechanical drives that provide reliable protection for actors, scenery and equipment.

The trend towards increasingly powerful drives for stage engineering applications has resulted in upper stage machinery with load capacities of up to one ton at speeds up to 1.8 m/s. "Series of tests at these capacities indicated that we could not simply continue using the construction design we had been using until now," explains Volker Kirsch, Director Sales Stage Technology at Bosch Rexroth.

Rexroth engineers performed extensive series of tests in a test field specially constructed for typical stage engineering drive systems. The result: Tests were performed in a test set up that was designed to closely recreate the conditions found in a theater. The results showed that the load to be moved and the drive were subjected to loads far greater than twice the nominal load. This means that all components in the force flow have to be designed to be far stronger.

Manufacturers and users now must face the new challenges. Bosch Rexroth has already turned the test results into solutions. For instance, safety equipment based on hydraulic components from Rexroth exhibits significantly softer emergency stop behavior. Rexroth has designed a damping device especially for electromechanical winches, which ensures soft emergency stop behavior on stage engineering systems. These devices can be easily implemented in new systems and in existing set-ups.

Rexroth will be comparing relevant variants under real conditions at their StageISetIScenery trade fair stand. Moreover, a special smart measuring instrument on a real fly winch will enable visitors to understand how soft-actuation brakes and an emergency stop absorber work.

Secure motion with collision control

Modern stage technology enables increasingly challenging motion sequences with numerous complex drives. These sequences often include multi-dimensional and interdependent motions. A clear view on the drives is often restricted due to decoration and curtains. The two collision control modules of the SYB 3.0 stage control system developed by Rexroth assist technical personnel with challenging tasks.

High-performance winches in the upper machinery: Mechanical load often underestimated

Current measurements at installed upper machinery drives prove that in case of a category 0 emergency stops, the load on the mechanics is much higher than previously assumed. In reality, the design criterion of twice the rated load prescribed by DIN 56950-1:2012-05 is often critically exceeded by the simple accident load. This may result in considerable risks for human beings working under the hovering loads. Using a new mobile measuring device, stage operators are now able to measure the actual loads and to economically retrofit the high-performance winches that are affected.
