MaximB failsafe brakes are Spring Applied Failsafe, Hydraulic Applied Service Brakes (SAFHAS). Both braking mechanisms are enclosed in the same housing and are sealed and liquid cooled, working on the scientific principal of oil shear between the rotating and stationary components. The unit has separate service and failsafe systems providing a very robust and safe solution for brakes used in mining.
The brake operates in two ways:
Service braking:
- The service brake is applied by exerting pressure using the standard foot brake valve.
Failsafe braking:
- The Emergency Stop button is pressed.
- The engine stalls.
- The engine is switched off.
- The door switch or seatbelt switch (additional safety features) is pressed.
