Compact multi-circuit brake
Double safety utilising redundancy also means double the braking torque. On designs with two independent brake circuits, this puts enormous mechanical strains on systems and components. Mayr Power Transmissions have solved this problem by developing a new multi circuit brake, the ROBA-quatrostop.
The new brake offers redundancy without doubling the brake torque, hence braking the system gently, reducing stress on associated components and saving cost due to more economic system design. The ROBA-quatrostop incorporates four independent braking circuits which are integrated into an extremely compact unit. Three circuits ensure the necessary safety with the fourth offering the required redundancy therefore the braking torque is increased by only 33%.
The unit is an electromagnetic, spring applied safety brake. When power is removed from the system for any reason, including emergency stops, the brake offers reliable and safe stopping in any position. The very compact design ensures easy handling and minimum space requirements.
