MAYR Safety Brakes Model ROBA Stop Silenzio Duta Perkasa
Characteristics
- Dual circuit brake as redundant brake system with a very short construction length
- Microswitch or proximity switch can be mounted for release monitoring
- Simplest possible installation
- No air gap adjustment necessary
- Continuously low noise levels for several hundred thousand switchings
- From size 200 on, the brake types with release monitoring are approved as protection against excessive upwards speeds and are also compliant with EN 81-1:1998 + A3:2009.
The quietest safety brake
Due to a newly developed noise damping unit, the ROBA-stop®-silenzio® is the quietest safety brake on the market, even in its standard version (pages 6 to 9). In new condition, the noise level is < 50 dB(A) (sound pressure level measurement). This value lies well below the noise level of the mounted drive elements such as e.g. motor and gearbox. Further noise reduction is
possible. We can accord with your request as far as noise levels are concerned, and guarantee our performance with a legally binding inspection protocol.
High operational safety
The ROBA-stop®-silenzio® is available as a single circuit brake or as a dual circuit brake. On the dual circuit brake, two independently operating brake bodies ensure high operational safety. Certain variants of this brake type series fulfll the requirements acc. DGUV Rule 115-002 (previously BGV C1), DIN 56950-1, EN 81-A3 and can be designed according to the requirements stated in ASME A17.
Simple installation
The compact design as well as the single-part toothed hub ensures simple handling and installation. The working air gap is pre-set and needs no re-adjustment. This means that malfunctions due to operating and adjusting mistakes can be ruled out.
Safe choice due to large type and size variety
12 construction sizes in different designs fulfl the demands for elevator and stage drives with a braking torque range of 2 x 3 Nm to 2 x 2150 Nm and therefore cover all required operation areas. If the power is switched off or in case of power failure or EMERGENCY STOP, the brakes ensure reliable and secure holding in any position; therefore, the brakes are intended mostly for static application as holding brakes.
Optimised construction space
Due to new construction and removal of the complicated intermediate flange plate, we have been able to create a unique short construction length.
Duty cycle
The ROBA-stop®-silenzio® safety brakes are optimised for a relative duty cycle of 60 %. For higher duty cycle, please contact the manufacturers. A duty cycle > 60% can lead to higher temperatures, which may influence the noise and switching behaviour of the brake.
Brake monitoring for maximum safety
The ROBA-stop®-silenzio® safety brakes are confgurable 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:
- Safe brake control
- Conditioning of the friction linings
- Refreshing of the friction linings
- Fail-safe release monitoring for checking the switching condition of the brake
- Wear inspection of the friction linings
- Monitoring and evaluation of the friction system temperature
- Static and dynamic braking torque tests
