The construction of the arm will be made of hot dipped
galvanized steel HSS of 60 mm in diameter with vertical posts
made of hot dipped galvanized steel HSS of 43 mm distanced from
± 1524 mm and cross-stiffeners in hot dipped galvanized steel
HSS of 33 mm in diameter, welded in place. The bowed stiffener
in hot dipped galvanized steel HSS of 43 mm is welded on the
vertical posts on the inside of the perimeter. The wire-netting
will be made of 50 mm chain linked industrial wire #9 . The
wire-netting is attached to the posts with different bands. The
galvanized steel barb wires will be attached to the end posts
with tension bands and eye bolts. Each row of barb wires will go
through the holes into the intermediate posts. The three rows of
the barb wires will have a total height of 305 mm above the
gate.
The maximum length available for the arm is 6096 mm x a height
of 1829 mm.
|
The counterbalancing 3048 mm long (or proportional to the length
of the gate) will consist of hot dipped galvanized steel HSS of
60 mm in diameter locked by hot dipped galvanized steel HSS of
43 mm cross-barred, solidly welded. The wire-netting is the same
as the gate arm.
|
The gate arm and the counterbalancing assembly will be in hot
dipped galvanized steel.
|
The hot dipped galvanized steel supporting posts will be 100 mm
in diameter x 4.8 mm thick driven into the 25 mPA cement pillars
at a minimum depth of 1524 mm. The supporting posts will also be
cross-barred with hot dipped galvanized steel HSS of 50 mm in
diameter. The distance of the supporting posts is proportional
to the length of the gate.
|
The aluminium guiding rail, designation 6063-T-52 with a yield
strength of 24,000 psi, will be bolted to the top of the hot
dipped galvanized steel HSS of the of the gate at every 410 mm.
Inside the guiding rail will be the 2 trolleys of 4 heavy duty
sealed bearings for sliding and 2 wheels to guide the gate in
its axis. These trolleys will be provided with an
auto-adjustable axis with bearing that will be bolted on the
supporting posts. The bottom guiding wheels will be fixed to the
supporting posts.
|
OPENING/CLOSING MECHANISM:
|
The gate operates with a galvanized steel rack-and-pinion
attached to the bowed stiffener with supporting braces to keep
the axle of the gate and linked by a sprocket to the electric
operator mechanism.
|
This unit is universal i.e. it can be installed either on the
left or on the right. This unit is provided with a 40:1 ratio
gear reducer. The motor is protected against overcurrent by an
overload relay that can be reset automatically.
This unit is equipped with an adjustable automatic friction
clutch that protects the gate and the operator in case of an
obstruction.
The rotary type limit switches are easily adjustable in both
directions. The motor can be removed easily without disturbing
the limit switches adjustment.
The 1 HP motor is available in 208, 460 or 600 volts, three
phase.
The electric operator is equipped with a self adjusting solenoid
drum brake with a 360° friction surface area.
The manual disconnect permits the gate to be independent for a
manual operation and an electric interlock will cut the power to
the control circuit during the operation. It will not be
necessary to remove the driving chain and the limit switches
will not go out of adjustment. The reversing contactor is a
heavy duty industrial type, Allan-Bradley or equivalent, with
mechanical interlock.
The base and the cover of the operator is in steel with ball
bearings tension sprockets mounted on a steel shaft of 25 mm in
diameter. The cover and the intermediate plate can be removed
easily for maintenance. A thermostatically controlled heater is
provided inside the cabinet.
This operator can operate with a #50 roller chain or with a
rack-and-pinion mechanism installed on the gate arm to give much
higher efficiency and durability outputs.
The cabinet is spray painted in blue.
|
HEAVY DUTY CONTROL CABINET:
|
The control cabinet will be EEMAC type 4 inside which will be
mounted the 1 HP electric operator in 208, 460 or 600 volts,
three phase; the relays; the contactors; the DC2000 dedicated
logic controller; 20% more terminals to hook-up any other
accessories or electric equipments. This unit is provided with a
40:1 ratio gear reducer. The motor is protected against
overcurrent by an overload relay that can be reset automatically.
The cabinet will also be provided with a thermostatically
controlled heater; one 110 volts plug-in; one 25 watts service
light with a switch; one breaker to cut the power and one
disconnect lever arm to operate the gate manually in case of a
power failure.
This unit will be equipped with an adjustable automatic friction
clutch that protects the gate and the operator in case of an
obstruction.
The rotary type limit switches are easily adjustable in both
directions. The motor can be removed easily without disturbing
the limit switches adjustment.
The base and the cover of the operator is in steel with ball
bearings tension sprockets mounted on a steel shaft of 25 mm in
diameter. The cover and the intermediate plate can be removed
easily for maintenance. The cover of the cabinet will be
lockable.
The cabinet is spray painted in blue.
|
On the vertical face of the gate arm, closing side, is installed
an AGDS safety edge working with a receiver/transmitter. When
touched, the safety edge stops the gate and reverses it to its
open position.
|
For an easy working condition, a shelter is available so that
the gate arm slides inside a tunnel the whole length of the
total opening, consisting of all-metal sheetings for the sides
and a roof. This shelter prevents from shovelling during the
Winter seasons. The shelter is made different ways with
different materials.
|
Maximum width of the gate: 9144 mm.
|
Manufacturing specifications may change without prior
notice.
