Additional measures need to be taken to minimize risk of accidents in areas where there is a danger of loads falling. Vertically moved heavy masses, in particular, may, in case of power failure, may inadvertently accelerate or drop uncontrollably; thus constituting a safety hazard. A brake system developed by mayr, ROBA-topstop is capable of providing safety in operations along the vertical axis. It has individual brakes and redundant dual-brake modules as per DIN EN 954-1, categories 1-3. Due to their adapted flange dimensions, the brakes can easily be integrated into pre-existing constructions between the servomotor and the counter flange. The modular assembly allows various designs to be implemented; with or without shaft, with flexible coupling, with additional safety clutch for torque limiting, or with two individual brakes. Using the brake system with a hollow shaft and an integrated insertable shaft coupling eliminates the need for a separate compensation coupling and the coupling housing. As an independent module the brake system can hold the vertical axis in any required position. Additional provisions for axis support are unnecessary. If the units are equipped with the proper functional and wear monitoring systems, the device can guarantee the “safe brake” function.
