FITTING AND CONNECTION INSTRUCTIONS

ENGLISH

The LYRA JACK consists of a hydraulic pump and a hydraulic
jack. The jack is placed inside a non carrying or carrying box
(inox only for carrying box).
The pump unit casing, which is used as an oil tank, contains the
electric motor, fluid pump, distributor and hydraulic oil. It is also
provided with an adjustable slowing-down device in the two
stop phases of the leaf (versions with slow-down only).
The wheeling unit is composed by a double piston connected to
a rack which engages with the pinion of the leaf dragging shaft.
Gates up to 2 meters long can be securely locked using the
operators internal hydraulic locking system, thus ensuring
perfect keeping in closing and in opening. For gate in excess of
stated value: A hydraulic non locking operator should be used in
conjunction with a separate electrical locking device to ensure
keeping in closing.

On the operators with hydraulic slow down it is present
only during the last 15° of rotation. The system comes with a

release which allows the manual opening of the leaves in case of
power failure.

1. GATE ARRANGEMENT

You must do some checks on the gate to see if fitting a LYRA,
JACK system is possible:
A. (Make sure that) the fixed and moving parts of the gate are
strong and non-deformable;
B. the weight of each gate leaf must not exceed 400 kg (Jack

400), 800 kg (Jack 800), 1200 kg (Jack 1200) see the graphic
(A);
C. the hinges and general structure must be in good condition

Leaf length M

and the gate must move smoothly throughout its travel;
D. the upper hinge alone is sufficient to install the unit; those
which are unnecessary can be eliminated (the lower and that in
the middle if exists);
E. as the limit switches are not provided within the actuator, it is

necessary to install mechanical limit switches stops to be fixed to
the ground in closing and in opening (Fig. 7).

2. NON-CARRYING BOX INSTALLATION

2.1. The excavation which contains the non-carrying box must

have the approximate dimensions mentioned in Fig. 8. For a
correct placing, it is obligatory to closely follow the quote of 55
mm which corresponds to the minimum distance of the rotation
axis from the pillar.

2.2. Inside the excavated pit you have to plan:

- rain water drainage;

- a water waste pipe in flexible plastic of about 40 mm of
diameter to put inside the provided hole of the box before it is
concreted (Fig. 9). It must be brought to the drain of the
sewer line;

- a sheath for the passage of the hydraulic tubes of about 32
mm of diameter which must be brought to the proximity of the
hydraulic unit box (Fig. 9).

3. INSTALLATION OF THE OPERATOR
INSIDE THE NON-CARRYING BOX

3.1. Place the jack inside the foundation box (Fig.12)

positioning the axis of the output shaft aligned with the axis of
the hinge of the gate and weld the four angular ends to fix the
same (Fig. 13).

Fig. 12

Fig. 9

2.3. Before concreting the box, use a level to make it perfectly
horizontal to the ground (Fig. 10) and perpendicular to the axis of
the gate (Fig. 11).

4. MOUNTING OF THE LEAF ON NON­CARRYING BOX

4.1. Insert the broached bush on the shaft of the jack.

Turn the shaft of the jack toward closing until it stops.

WARNING: For operators with brake make sure that the jack
has reached the stop and not the beginning of the
slowdown.

4.2. Go back about 5° and weld the bush to the U-shaped bar

(not supplied) and to the leaf of the gate (Fig. 14).

4.3. Be careful not to place the leaf outside the axis (Fig. 16
and 17) and make sure that the shaft corresponds to the
rotation axis of the jack.

5.1. Connect the hydraulic tubes with the hydraulic unit and the
jack (Fig.21, Fig.22, Fig.23).
After having installed the box, the gate and the operator, try to
slowly move the gate by hand to make sure that there are no
irregular frictions and that the movement is uniform for the whole
range.
Notice: To do this last operation, release the operator as
described in the related paragraph.

8. BRAKING REGULATION (where present)

8.1. It is possible to regulate the leaf slowdown in opening and in

closing, through the braking adjusting screw (Fig. 26).

8.2.To regulate slowdown operate as follow:

- Loosen the blocking screw of braking regulation;

- Act on the adjusting screw clockwise to have a higher braking
and a speed decrease;

- Act on the adjusting screw anti-clockwise to have a lower
braking and a speed increase;

- After the regulation fix the blocking screw of braking regulation.

On the operators with hydraulic slow down it is prensent
only during the last 15° of rotation.

7. FORCE ADJUSTMENT

If necessary the thrust force of the leaf can be adjusted by the
two adjusting screws (grey and yellow) placed on the front lower
place of the hydraulic pump unit (Fig. 25).
*The operator is adjusted at 15 Kg force ex works so to
guarantee the anti-crush safety.
We recommend to adjust it only in case of necessity.

9. BLEEDING OPERATION

During the connection phase between hydraulic unit and jack, air
will inevitably enter into the system and cause an irregular
operation of the operator. The irregular operation shows by an
abnormal movement of the leaf and excessive noise during
operation. To solve this problem it is necessary to proceed as
follows:
