your reliable partner Elevator Brakes Never compromise on safety

Safety does not allow for compromises   For more than 100 years, the company mayr ® power transmission has stood for innovations and premium quality. The family-run company from the Allgäu region can rely on decades of experience in development, manufacture and application, and is today the world market leader in the field of elevator brakes. The low-noise, patented brakes by mayr ® provide reliable protection in multitudinous elevators around the globe. No matter where people are moved by elevators - whether in skyscrapers, in shopping centres or residential buildings, in hospitals, at airports...

Expert know-how in Tested qualitydevelopment and design and reliability As the technological leader, mayr® power transmission focuses on continuous further development. Today, highly qualified engineers and technicians work on tomorrow's innovations using the most up-to-date tools. The many years of experience and countless trials carried out by the Research and Development department at the headquarters in Mauerstetten form the basis for a conscientiously-planned service lifetime, taking into account realistic and verified braking torque tolerances. The values upheld by our traditional, family-run...

Signed and sealed ®  mayr power transmission is prepared for the new elevator standards EN81-20 and EN81-50: The safety brakes are prototype-inspected by the TÜV Süd (German Technical Inspectorate, Southern Germany). Moreover, we have had branch-specific brakes, couplings and clutches tested and certified for safety-critical and unusual applications by independent institutes. They confirm our claims as to quality and reliability. Elevator brake as part of the protection device against overspeed for the elevator cage moving in an upwards direction. Simple implementation of the elevator standard...

Safety Brakes Experts instead of experiments   Today, safety brakes are an indispensable safety feature in modern electrical drives. mayr ® power transmission consistently takes the following basic safety principles into account during development and manufacture: The electromagnetic safety brakes ROBA-stop® operate according to the fail-safe principle, they are therefore closed in a de-energised condition. The braking torque is generated by the force stored in the thrust springs. If the magnetic coil is energised, a magnetic field is built up which attracts the armature disk against the force...

Innovative: Contactless release monitoring An indispensable element for safety brakes fulfilling the DIN EN 81 standard requirements is the integrated function monitoring. This release monitoring prevents unpermitted operating conditions, such as for example the motor starting up against closed brakes. mayr® power transmission as the leading manufacturer offers a unique innovation as an alternative to release monitoring with microswitches: A contactless system with an inductive proximity switch registers the operating condition of the brake and authorises the motor to start up only after release....

Aiming high: Skyscrapers Whether in passenger elevators in the World Financial Center in Shanghai, in the Buddha Tower in Xian or in many other skyscrapers in the metropolises around the globe — ROBA®-diskstop® brakes are characterised through high energy absorption capability in case of dynamic braking actions. Therefore, they are perfectly suited for application in elevators with high speeds and masses. The classic caliper brakes are prototype-inspected according to EN81 for the elevator sector. Through slight modification, conformity according to ASME A17 can also be achieved if required....

The safe route to work   The compact, extremely short ROBA®-twinstop® brakes safeguard passenger elevators in offices and commercial buildings. They consist of two independent brake circuits, which can be tested individually. Due to the patented noise damping system, these brake type series switch extremely quietly. ROBA®-twinstop® The compact brake for gearless elevator drives ●● Different sizes ●● Various configuration possibilities such as hand release, release monitoring, encoder integration ●● Electrical single-circuit inspection possible via two integrated magnetic coils

The shopping centre as a meeting point Shopping centres are normally full of busy shoppers and sellers. In the elevators in such centres, ROBA®-diskstop® brakes, for example, guarantee maximum functional and operational safety. They switch very quietly and without grinding in operation due to a parented alignment mechanism. The brakes can be mounted quickly and easily; adjustment work is not necessary. ROBA®-diskstop® The modular system for brake disks • Four standard sizes • Different brake disk diameters • Modular number of brake units per disk • Attractive solution for large braking torques...

Where reliably functioning technology is essential: Hospitals In hospitals, elevators must take patients, staff and visitors quickly and reliably to their destination - and not just in emergencies. Here, for example ROBA®-sheavestop® and ROBA®-silenzio® brakes guarantee maximum safety for people and systems. The brakes are suitable as a protection device against overspeed for the elevator cage moving in an upwards direction. They are mounted on transmission machines directly onto the drive sheave or onto the side opposite the transmission output shaft. ROBA®-sheavestop® and ROBA-stop®-silenzio®...

Residential buildings — Safety for household elevators   Private elevators and household elevator applications guarantee comfort and barrier-free homes. For these elevators, mayr ® power transmission offers the ROBA-stop®silenzio®, the ROBA-stop®-M or the ROBA®-secustop safety brakes as the ideal solutions for different drive constellations. The brakes in single-circuit or dual-circuit design fulfil the maximum safety requirements, are unbeatably low-noise and their compact design offers innovative possibilities for economical solutions. Reliable and flexible — Different single and dual-circuit...
