电梯和舞台制动器: Have proven their worth thousandfold and are low-noise

The safest choice is first and foremost a supplier that is a leader in its field. A market-leading company has extensive experience in the relevant fields of application and is also recognized by testing authorities. Certification according to common quality standards, such as ISO 9001, is also an important criterion. To ensure you equip your application with the best and most reliable safety brakes on the market, you should objectively take the following points into account: 

• Visit the factory of your brake supplier. On site, you can make sure they offer the right manufacturing expertise, a certified quality process as well as test and inspection facilities necessary to manufacture the perfect safety brakes. 

• Make sure the manufacturer performs full and thorough output inspections, all brakes are declared with serial numbers, and tracking is guaranteed. 

• You should also sample your future safety brakes under critical conditions. A design focused on safety is an absolute must, and flawless, low-noise operation should be ensured even after several million switching cycles. 

The right supplier for elevator brakes must be a reliable partner, capable of ensuring consistent availability, service, and support over a long time. This is the only way to guarantee the necessary safety for elevator projects.
This means that to be the right choice, it’s important that the supplier not only has extensive practical experience but also offers a broad product portfolio. This allows them to provide solutions tailored to the specific application. Having reliable service and experienced, well-trained staff is also essential.

The right stage brakes come from an experienced, reliable manufacturer with extensive practical expertise. This ensures users can meet all relevant standards and regulations. Stage applications pose unique challenges, as people’s safety must always be the top priority. Safety brakes should also operate as quietly as possible to ensure performances can be enjoyed without interruption. Alongside high-quality products that conform to standards, service is also an important selection criterion. At mayr^®, designers receive a comprehensive checklist with the brake validation tool, which not only includes questions and information aligned with common standards but also key data such as the B10d safety rating. This makes checking that the right brake has been selected simple and reliable.

Electromagnetic mayr® safety brakes for elevators and escalators are available in various designs for different constructions, drives, and industry sectors. From modular brake disk systems to cost-effective braking solutions for geared and gearless drives, as well as robust motor brakes and various single- and dual-circuit brakes for different applications, mayr® offers a safe and reliable solution for every elevator application. All mayr® elevator and stage brakes are noise-damped and remain low-noise throughout their entire service lifetime. A patented metallic damping system ensures temperature stability over the entire service lifetime and allows brakes to be monitored without sensors.

mayr^® offers a range of stage brakes, most of them with two redundant brake circuits. With the ROBA-stop^® stage, mayr^® provides a brake with a redundant switching function through two opposing brake circuits, but without doubling the braking torque. All our stage brakes are noise-damped, making them low-noise. We offer the quietest stage brake on the market thanks to the ROBA-stop^® silenzio^®. mayr^® power transmission stage brakes can also be configured for comprehensive brake monitoring. They can guarantee maximum operational and functional safety due to the permanent monitoring of the brake condition and the optimisation of the friction system.

mayr^® offers comprehensive electronic accessories with their elevator brakes for an aligned overall system. In addition to spark quenching units to prevent the creation of sparks on switching contacts, this includes half-wave and bridge rectifiers as well as ROBA^® switch and ROBA^® multiswitch fast acting rectifiers. The safety brakes are controlled using these rectifiers: They connect the brakes as DC consumers to the alternating voltage supply and allow the implementation of short overexcitation operation and/or voltage reduction.

Innovative ROBA^® brake-checker modules enable permanent brake monitoring via the sensorless monitoring of the brake condition. The “plus” versions of the ROBA^® brake-checker^® also feature a fast acting rectifier.

mayr^® is certified as a reliable supplier according to DIN EN ISO 9001:2015. We are also an authorized economic operator (AEO)

Leading OEMs around the world rely on mayr^® braking technology in their elevators. Our ROBA^® diskstop^® brakes are used in a number of high-rise buildings worldwide, including the World Financial Center in Shanghai and the Buddha Tower in Xi’an. Even in the world’s tallest outdoor elevator, the Bailong Lift in Zhangj iajie in China, mayr^® brakes ensure comfort and safety.

Stage brakes by mayr ^® power transmission make an appearance on the large theatre and opera stages of this world on a daily basis. But even in case of large-scale sporting events, such as at the Football World Championships or the opening ceremony of the Olympic Games, during large TV productions or on state of the art cruise ships — mayr ^® brakes, clutches and couplings are live on set and secure machine movements in front of and behind the scenery. The stages of the Bavarian State Opera and the Theater am Gärtnerplatz in Munich are also equipped with mayr^® brakes, as is the world-famous Bolshoi Theatre in Moscow.

1.      Elevator and stage brakes are classified as safety brakes. At mayr®, we equate the term safety brakes with the fail-safe principle: our spring-applied safety brakes are closed in their de-energized state. If the power is turned off or unexpectedly fails, our brakes close by means of spring force, which ensures reliable and safe braking of machines and systems in any position.

We make no compromises where safety is concerned. Therefore, all our safety brakes also exhibit the following traits:

·         Short switching and braking times

·         Safety-oriented dimensioning

·         Reliable spring force

·         Application of basic and established safety principles

·         100% end-of-line brake inspection

·         Reliability thanks to many years of field experience
