Options
- Release device: For all operators with mechanical brake, the gates are blocked in case of power failure. If the gates have to be moved manually even in case of power failure, the following options are available: additional mechanical release device or electromagnetic clutch.
- Brake: Equipped as standard with a mechanical brake that stops the gates within the prescribed paths even in the event of a power failure. For gates not covered by EN 12453, the operators can be supplied without brake.
- Accessories: Due to the extremely large forces when the mechanical brake is applied, very stable fastenings are required. Rail mounting is generally not possible. Additional brackets are available for wall mounting.

6. Wall bracket
7. Support roller with U-holder for the toothed belt (to prevent the toothed belt from sagging – from 4 meters free running toothed belt)
8. Additional belt fixing bracket with clamping plates for toothed belt, for double-leaf gates
Additional components (not depicted)
- Mechanical release device: Due to the built-in brake, the DICTAMAT sliding gate operators are blocked in case of power failure. With the help of the manual release clutch, the output wheel is disconnected from the gearbox via the rope supplied and can be moved freely. The gate can thus be moved smoothly. The rope must be fixed manually.
- Electromagnetic clutch: Thanks to the built-in brake, the DICTAMAT sliding gate operators are blocked in the event of a power failure. With the help of the electromagnetic clutch, the output wheel is automatically disconnected from the gearbox in case of power failure and can be moved freely. The gate can thus be moved easily. The electromagnetic clutch is supplied via a separate power supply unit. A separate capacitor pack is required to ensure safe braking in the event of a power failure.
