11 AVAILABLE ACCESSORIES
11.1 ANTI-VANDAL VALVE (Fig. 19a)
It protects the hydraulic system if the beam is forced.
11.2 AUTOMATIC EMERGENCY RELEASE (Fig. 19b)
During a power cut, the automatic emergency release allows you to manually lift the beam without accessing the release lever
of the hydraulic control unit. A hydraulic system guarantees that the beam is stopped in the opening position.
11.3 FORK SUPPORT
The fork has two functions:
-
it prevents the beam, when closed, from bending and splitting if its end is stressed by extraneous forces.
-
it allows the beam to rest when closed and thus prevents the profile bending downward
To position the fork support foundation plate, refer to fig. where:
P1 = barrier foundation plate
P2 = fork support foundation plate
L = beam length (in mm)
A = distance between foundation plates
