SLIDING GATES
Fitting the bar rack
4.3
The rack
CZ
is a Galvanized steel rack. Fixing is made using
the relevant spacers to be welded on the gate base.
Caution
The different components of the rack must be well
aligned with each other.
The pitch between the teeth must be kept constant in
the joints.
The rack HEIGHT must be respected (Fig.14) and
adjusted to prevent the weight of the gate falling on the
gearmotor.
Warning
!
To prevent gate from weighing on the operator pinion,
the whole rack must be raised by 1.5 mm using the row
of slots for the different rack components; only after
this can the fi xing screws be fully tightened.
NEVER LUBRICATE THE RACK.
Warning
!
DO NOT weld the rack sections directly on the gate panel and
DO NOT weld adjacent parts one to the other; do not close
the free space between them (any following adjustments
would be impossible).
Keep the negative lead of the welder CLEAR OF the gear
motor.
NEVER WELD WHEN THE GEARED-MOTOR IS
CONNECTED TO THE MAINS.
ALWAYS PROTECT THE WELDINGS WITH A ZINC-
BASED RUST-PREVENTER SPRAY.
Throw the gate open.
•
Fix the spacers
•
to the steering rack with screws and
washers, making sure that the screws pass through the
centre of the slot (
Fig.15
).
Position the initial section of the steering rack on to the
•
pinion of the gear motor.
IMPORTANT:
align the fi rst slot
with the vertical axis of the pinion
(
Fig.16
).
Move the spacers in contact with the gate, then fi x the fi rst
•
spacer to the gate with a welding spot (
Fig.16
).
Release the gear motor
•
(see paragraph)
and move the gate
by hand until the second spacer is aligned with the vertical
axis of the pinion, then fi x the spacer to the gate with a
welding spot (
Fig.17
).
Move the gate over the fi rst section of the steering rack.
•
Use a 20 cm-long piece to the steering rack (
•
Fig.18-ref.1
)
as a template. Near the second section of rack to the fi rst
one by bringing it in contact with the template. By moving
the gate by hand, position the fi nal part of the second rack
section on the gear motor pinion.
Position the spacers of the second rack section on the
•
gate and fi x them with two welding spots.
Repeat the steps above with all elements of the steering
•
rack you necessitate.
At the end of the positionings weld defi nitively all the rack
•
spacers to the gate.
IMPORTANT!
WELD
THE
SPACERS
ALONG
THEIR
ENTIRE
CIRCUMFERENCE
.
At the end of operations, re-lock the gearmotor
•
(see the
paragraph)
