BALANCING OF THE BOOM

Size the boom length before installation: the boom is
modularized, cut or join according the length you need.
Fix the boom as shown in the picture.
Once the boom is fixed on the barrier and for any
reason the length has to be changed, proceed
to readjust the springs and the limit switches, in
the following way:
If the length has been decreased, the boom may
lift up a little bit, therefore proceed to reduce the
number of spring.
On the contrary if the length has been increased,
the boom may get down, therefore proceed to fit
both springs.
Look at the below table to fit correctly the springs
according to the boom length :
Boom length Springs
3 - 4 m
4,5 - 5 m
6 m
Fit the springs, by number and type, following the
instructions shown here in the picture.
The tension of the spring has to be as much as to allow
to lift the boom safely and easily with your hand.
Once the springs have been adjusted, proceed to align
the boom when in horizontal position.
