Several ceiling-mounted operators with chain transmission are available for Ballan sectional doors.
Automatic S/550, S/800 and S/1100: with chain or lateral drive
Automatic A/310 and A/315: the reliability of a chain-driven system
The operators are made up of a 24 V direct current irreversible mechanical gearmotor with control panel, incorporated lamp and manual
operating system to be used in case of a fault or electric blackout. Chain-driven ceiling-mounted operators, become a lock due to their
irreversible motors. They are anti-crushing by virtue of the greater sensitivity of the motor and have an incorporated electronic control unit that checks the safety devices during each operation and can be interfaced for maintenance management and for reprogramming if needed.
Automatic B/500 - B/400: the lateral operator for constant efficiency
Automatic B/500 and B/400 are lateral operators for civil and industrial use, exclusively for large size doors.
These drives are made up of an electromechanical operator, fitted in the lateral sliding guide, complete with control unit (with "open-close" button), spring shaft adaptor, "sicur-stop" safety devices and a pair of wall-mounted photocells.
