DESCRIPTION

1. Housing made of folded and welded sheet steel, from 2 to 6 mm thick, protected by cataphoresis and two coats of structured paint (standard color: orange RAL2000).
2. Internal mechanical elements treated by electrogalvanisa- tion.
3. Side door giving access to the mechanism, with security lock.
4. Removable cover, locked by key.
5. Aluminium tube boom arm, varnished white with red reflecting stripes and end-sealing.

Boom arm swing-off, avoiding damage to the barrier in case of impact on the boom arm.

1. Arm shaft mounted on two life- lubricated ball bearings. The protrusion of the shaft, centred on the housing side, allows it to be

easily reversed from one side of the housing to the other: arm on the left or on the right of the framework housing.

1. Arm balancing by springs.
2. Electro-mechanical assembly including:
   • An asynchronous three-phase geared motor.
   • Movement transmission by crankshaft-rod device insuring mechanical locking of the boom arm in end positions.
   • Automatic barrier unlocking device in case of power failure, opening then being possible by hand.
   • Frequency converter ensuring progressive accelerations and controlled decelerations, for a vibration-free movement and enhanced protection of the mechanism.
   • Analogue inductive limit switch that detects the extreme positions (open/close) and informs at any time of the exact position of the arm for a better control of the movement.
3. Lever for manual unlocking (if not automatic mode set up).
4. Control board enabling various additional commands and/or accessory options
5. Adjustable information contacts:
   • State of the barrier’s position (open or closed),
   • State of the presence detectors,
   • Command for master-slave barriers (movement of one barrier controlled by the other barrier),
   • ...
6. Fixing frame to be fixed in a concrete base to be provided by the customer.
