If there is no support surface:
1. dig the hole to insert the foundation plate
Note The anchoring surface must be completely at and
smooth. If the surface is made of concrete, the latter
must be at least 0,15 m thick and must be suitably rein-
forced with iron cages. The concrete must have a vol-
ume above 0.2 m

(a 0.25 m thickness corresponds to
0.8 m

, that is, equal to a square base with sides each
measuring roughly 0.9 m). The plate can be anchored to
the concrete using the 4 expansion bolts, equipped with
12 MA screws capable of withstanding a tensile load of
at least 400 kg. If the anchoring surface is made of a
different material, it is necessary to verify its consistency
and whether the four anchoring points can withstand a
load of at least 1,000 kg. Use the 12 MA screws to fas-
ten the plate.
2. arrange the pipes for routing the electrical cables
3. fasten the four anchor bolts (A) to the foundation plate, in-
serting a nut and washer (supplied) on each, on the upper
and lower sides of the plate
m
The lower nut must be screwed up to the end of the
thread.

4. pour the concrete and, before it starts to set, place the
foundation plate ush with the surface, parallel to the
boom and perfectly level
5. wait for the concrete to set completely, which generally
takes two weeks
6. remove the four upper nuts and washers (B) from the an-
chor bolts
7. open the cubicle panel (“Figure 7“)
8. arrange the cubicle properly and secure it with the ap-
propriate nuts and washers removed previously (“Figure
14“).
3.8 INSTALLING THE BOOM
Proceed as follows to mount the boom of the gate:
1. insert the two pins (A) through the appropriate housings
on the exit motor shaft

2. place the support (B) on the exit motor shaft, orienting it in
the “vertical boom” position
3. fasten it with the appropriate screws and open Grower
washers; tighten vigorously
