The LYRA JACK is made of a hydraulic pump and a hydraulic jack. The jack is placed inside a NON-

CARRYING BOX or inside a STAINLES STEEL CARRYING BOX according to the model.

The LYRA pump unit casing is used as an oil tank and contains the electric motor, the hydraulic pump, the

distributor and the hydraulic oil. The JACK 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, to

ensure a perfect keeping in opening and closing. For gates of length over 2 meters it is advisable to use

operators without hydraulic lock and separate electrical locking device to ensure keeping in closing.

The operator can be optionally provided with an adjustable hydraulic slowing-down device operating in

both opening and closing (during the last 15° of rotation).

The operator is equipped with a release system for the manual opening of the leaves in case of power failure

1 - GATE ARRANGEMENTS

Before the installation, check that all gate parts (fixed and mobile) have a resistant and non-deformable

structure; also make the following checks:

1.1. the leaves must be rigid and compact;

1.2. the weight and length of each leaf should not exceed the values supported by the specific operator

model (see tables);

1.3. the hinges and the structure of the gate must operate smoothly throughout the execution of the

movement, without frictions or obstacles

ONLY THE UPPER HINGE IS SUFFICIENT TO INSTALL THE OPERATOR;

1.4. THE INSTALLATION OF THE MECHANICAL STOPS IN OPENING AND CLOSING IS ALWAYS NECESSARY

4.1. Insert the broached bush on the jack shaft.

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

4.3. Move the leaf back about 5° and weld the bush to the with «U» shaped iron bar (not supplied), and

to the gate leaf (Fig. 15)

4.4. Caution! Do not place the leaf outside the axes (Fig. 17 and 18); make sure that the shaft coincides

with the rotation axis of the jack (Fig. 16)

3 - «JACK» INSTALLATION INSIDE THE NON-CARRYING BOX

3.1. Place the jack in the foundation box (Fig.13), positioning the axis of the output shaft aligned with the

axis of the gate hinge; weld the 4 corners to fix (Fig.14)

4 - LEAF INSTALLATION ON THE NON-CARRYING BOX

FOR OPERATORS WITH BRAKE: MAKE SURE THAT THE JACK HAS REACHED THE STOP AND NOT ONLY THE

4.1. Place the gate leaf on the support rod, taking care to

make the rotation axis of the leaf hinge coincide with the

rotation axis of the support; be sure to respect the

perpendicularity with the rotation axis (Fig. 24 - Fig. 25)

4.2. Carefully weld the support rod to the leaf, making

fixing sections of about 3 or 4 cm along the contact

surface and avoiding welding near the threaded holes
