Doubled safety using redundancy also means double the braking torque on systems with two brake circuits – an enormous strain for all components. The brakes manufacturer from Mauerstetten in Germany, mayr® power transmission, has solved this problem by developing a new, multiple circuit stage brake, the ROBA®-quatrostop.
The new, redundant ROBA®-quatrostop with its four individual brake circuits brakes gently and exceptionally quietly.
The new safety brake for film, theatre and stage facilities is redundant without doubling the braking torque. This brakes system brakes gently, is gentle on attachment parts and saves costs through easier connection constructions. The ROBA®-quatrostop stage brake runs extremely quietly. It has four individual brake circuits, which are integrated into a compact, extremely short brake block. Three brake circuits together produce the required braking torque. The fourth, redundant circuit ensures the necessary safety. The braking torque is therefore only increased by 33 percent. All braking circuits can be switched and tested individually.
The ROBA®-quatrostop is an electromagnetic, spring applied safety brake. After switching off the power, on power failure or on EMERGENCY OFF, it allows reliable and safe stops in any position. The compact design ensures simple handling and installation. The working air gap is set at the manufacturing plant and need not be re-adjusted during operation. This means that functional errors due to operating and adjustment errors are prevented in advance by the design.
For maximum system and personal safety, each brake circuit is equipped with a release monitoring system for functional control. Stage brakes from the construction series ROBA®-quatrostop are mainly maintenance-free. The maintenance work is limited to the inspection of friction linings, which are extremely wear-resistant and achieve an extremely high lifetime.
Safety does not permit compromises. mayr® power transmission are international leaders in the development, production and implementation of safety brakes for theatre, film and stage facilities. Extremely quiet-running stage brakes by mayr® power transmission make a daily appearance at numerous events in very different locations all around the world. Based on 40 years of expertise in safety brakes, wide field experience in many thousands of applications and a very wide product range, the company provides technically perfect, economical and extremely low-noise solutions.Chr.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
