7. MECHANISM
7.1. OPERATING PRINCIPLE
The mechanical assembly, mounted on a mini chassis, allows the turret to perform rotational movements of 120°, which
corresponds to the passage of a user. During the movement, the stainless steel arm that is located horizontally releases
the passage by moving down.
This rotation can be carried out in the clockwise or anti-clockwise direction in order to control the flow of users in the
entry direction (direction A) and/or the exit direction (direction B).
The actuation of 2 mechanical locks, controlled by electromagnets, releases or blocks the passage in each direction.
An angular sensor detects the rotational movements of the turret in order to grant only one right of passage at a time, by
locking the mechanism again after a rotation of 120°.
In the event of a power failure, the electromagnets release the pressure on the locks, to release passage in both directions.
Optionally, the customer can reverse the operating logic by locking the passage in case of absence of supply voltage.
In the dropping arm option, each arm has a rotational axis at its attachment point to the turret. An electromagnetic
suction cup holds the arm in a horizontal position, and releases the arm in the event of a power failure, which completely
releases the passage in both directions (for an emergency evacuation).
An optional motorisation module performs a dual function:
• Rearming the TriLane dropping arm version after power failure by carrying out a complete rotation of the turret
following the initialisation process at power-up.
• Accompanying the user in transit; the motor engages automatically as soon as the angular sensor detects the start
of a rotation that follows the pressure of the user on the horizontal arm.
