7.3.1.
d
ropping
arm
option
The dropping arm option requires the installation of a suitable turret, equipped with an axis of rotation at the point
of attachment of each arm.
When the TriLane is powered, each of the three arms is held in position by a small latch fitted with a return spring.
In normal operation, an electro-magnetic suction cup keeps the latching actuator under pressure.
If there is a power failure, the suction cup is no longer powered and the stop of the dropping arm device hits one of
the three locks, which causes the horizontally-oriented arm to fall. The passage
becomes totally free.
The fall of the arm automatically returns the stop into contact with the suction cup, thus preparing the correct
positioning to the re-energisation.
A manual intervention is necessary at re-energisation, rotating the turret in order to position the arm horizontal,
which also resets the actuating device.
If the motorised option is selected, a turret rotation takes place automatically, which will reset the actuating
device without any external intervention.
In the dropping-arm option, the arm is attached at the height of the pivot, using a screw and an Allen nut (see the
codes below).
