Smart safety for vertical axes
08 December 2025
GRAVITY-LOADED axes in robotics applications must be safe; mayr power transmission's new generation of ROBA topstop safety brakes make this possible in smart environments.

The compatible ROBA brake-checker module enables permanent brake monitoring. Combined with the ROBA gateway, the system delivers valuable data for proactive machine maintenance, a digital twin, and smart production environments. In addition, a practical checklist supports brake validation.
The ROBA topstop holds the loads in position reliably and prevents uncontrolled movements in case of power outages or emergency stops. As they are placed between the motor and the output, the brakes can be retrofitted in existing applications.
For day-to-day industrial operations, the ROBA topstop braking system is equipped as an independent, compact module. O-rings at the interfaces ensure reliable sealing against dust and moisture and the brakes achieve IP66 protection as standard. The vertical axes remain secured even when the drive is dismantled, which is advantageous during maintenance and transport. Thanks to the adaptable flange dimensions, the system can be easily integrated into existing constructions.
