Professional solutions offered.
Please contact us for more
information.
In the modern times that we are living, with crime rampant,
it is essential that one’s garage doors should be opened and
closed automatically. It is also much more convenient for
the inhabitants of the house not to get out of his or her
car to open the garage doors, especially during the rainy
season or winter, or at night. It is not even safe during
daytime to get out of your car, let alone when you return to
your home late at night. It is known that a lot of car
hijackings take place at the victim’s home, when he or she
is about to park the car inside the garage. If your garage
door is automated, the risk of being hijacked is lessened,
as you only have to leave your car once you are inside your
home.
Roller Doors
SUPER LIFT: A reliable, efficient & affordable roll up
garage door operator for domestic use.
Manual Release
In the event of mechanical or mains power failure, the
operator is provided with a manual release mechanism
allowing the door to be operated manually

The motor is mounted on the inside of the drum, giving no
exposure to dangerous moving parts. The sensitive anti
crushing system adds to the safety features making it a
truly safe operator.
Powerful, Quiet DC Motor
A high torque DC motor will lift your roll up door silently
and reliably.
Minimum Side Room
The motor can be fitted in extremely narrow openings due to
the compact design of the unit.
Light your Way
A light comes on as soon as you activate the system
illuminating your garage while you get in or out of your
vehicle. The built timer switches the light off
automatically.
Easy to commission
Incorporating mechanical end of travel and safety force
micro switches, the opening and closing positions and anti
crush settings are simple and easy to adjust.
Take Control
Using NOVA rolling code technology the remote controls offer
the ultimate in security. Transmitting with each operation a
unique randomly changing code the remote control signal can
neither be grabbed nor copied.
Tip up Doors / Sectional Doors
 We
also supply and install spring balanced tip up automatic
garage doors which has no track mechanism. When the door
opens, a portion of the garage door moves through the
opening to the outside of the garage. When fully opened the
door is partly inside the garage. Garage door springs are
under tremendous pressure and should not be removed or
installed by anyone but an experienced garage door
installer. It is important to determine how many times a day
your door is opened, because that will determine which one
of 4 torsion spring cycles you choose for your garage door:
25 000, 50 000, 75 000 or 100 000 cycles, depending on how
often your door is opened daily. Take the number your door
will be opened a day, multiply by 250 days and multiply with
10, 10 being the years of your door’s lifetime before it has
to be replaced.
Maintenance and Safety
Garage Door System Safety - An
Automatic Decision
A Garage door is the largest moving object in the home. They
are often operated by electric door operators. Proper
installation, operation, maintenance and testing of the
garage door and electric door operator is necessary to
provide safe , trouble-free operation. An improperly
adjusted garage door or electric operator can exert deadly
force when the door closes. This could lead to serious
injury or even death from being hit by a closing garage door
or being trapped under the door.
Safety is everyone's business
A few simple precautions can protect your family and friends
against potential harm. Please take a few minutes to read
the following safety and maintenance tips. Refer to your
Garage Door and Garage Door Operator owner's manual for
details specific to the model you own to check the operation
of your garage door and garage door operator.
WARNING - DO NOT STAND OR WALK
UNDER A MOVING DOOR. DO NOT LET CHILDREN OR ADULTS PLAY”BEAT
THE DOOR “IT IS DANGEROUS AND CAN RESULT IN SERIOUS INJURY
OR DEATH. ADULTS SHOULD SET A GOOD EXAMPLE. KNOW HOW TO USE
THE EMERGENCY RELEASE IN CASE SOMEONE GETS PINNED BY THE
DOOR.
DO NOT LET CHILDREN PLAY WITH OR USE TRANSMITTERS OR REMOTE
CONTROLS. ALWAYS PLACE AND STORE THEM OUT OF REACH OF
CHILDREN.
THE WALL SWITCH SHOULD BE OUT OF REACH OF CHILDREN (AT LEAST
1.5 M FROM THE FLOOR) AND WAY FROM ALL MOVING PARTS. MOUNT
AND USE THE SWITCH WHERE YOU CLEARY SEE THE MOVING DOOR AT
ALL TIMES.
Teach Your Children About Garage
Door and Operator Safety
Garage door operators are not toys. Careless operation and
allowing children to play with garage door operator controls
can lead to tragic results. Discuss garage door safety with
children. Explain the danger of being trapped under the door
clearly.
When using the wall switch or transmitter, keep the door in
sight until it stops moving completely. Teach children to
never play under or near an open garage door.
WARNING - TEACH CHILDREN TO KEEP
THEIR HANDS CLEAR OF SECTION JOINTS, HINGES, TRACKS, SPRINGS
AND OTHER DOOR PARTS. CONTACT WITH A MOVING DOOR OR ITS
HARDWARE COULD CAUSE SERIOUS INJURY. THESE INJURIES COULD
ALSO HAPPEN WITH DOORS THAT DON'T HAVE OPERATORS INSTALLED.
Routine Maintenance Can Prevent
Tragedies
Take a few minutes to inspect and test your complete garage
door system. Make monthly inspections and testing a part of
your regular routine. Safety is everyone's business. Make
the safe use of garage door and garage door operator safety
mandatory in your home.

Testing and Maintaining the Garage
Door Operator
There are routine maintenance and safety steps you should
follow once a month. Review your owner's manual for the door
operator. If you don't have a owner's manual, look for the
model number on the back of the power unit and request a
manual from the manufacturer.
Reversal Test
Make sure your garage door operator has a reversing feature.
If a reversing feature is not present, the operator should
be replaced. Garage door operators manufactured after
January 1, 1995 are required by SABS - IEC Standard No.60335
Part 2 to have advanced safety features. Contact your
manufacturer or installer for additional information.
Test the reversing feature every
month:
First, test the balance of the door (see "Testing and
Maintaining the Garage Door"). If the door is properly
balanced, then proceed.
While the door is fully open, place a 40mm thick piece of
wood on the floor in the centre of the door.
Push the transmitter or wall switch button to close the
door. The door must stop and reverse when it strikes the
wood. (Note that the bottom edge of " one piece doors " must
be ridged so that the door will not close without reversing.
)
If the door does not reverse, have it repaired or replaced.
Have a qualified door mechanic adjust, repair or replace the
garage door or garage door operator.
Force Setting Test
Test the force setting of your garage door operator by
holding the bottom of the door as it closes. If the door
does not reverse readily, the force may be excessive and may
need adjusting. Always check the owner's manual for details
on how to make the necessary adjustments. Test the reversing
feature after every adjustment.
Additional
Safety Devices
Many garage door operators can be equipped with additional
safety devices. Consider adding an infra red beam or a
sensor edge to the door as an extra measure of safety to
protect against entrapment. Keep in mind that adding more
safety devices will not bring an old operator in line with
current safety standards
Make sure the additional safety devices, such as infra red
beams or edge sensors, are properly installed and adjusted.
Always consult the owner's manual for detailed information
on the settings and functions of these devices.
Testing and Maintaining The Garage
Door
Perform routine maintenance steps once a month. Review your
owner's manual for the garage door. If you don't have a
manual, look for the model number on the back of the door,
or check the lock handle, hinges or other hardware for the
manufacturer's name and request a manual from the
manufacturer.
Visual Inspection
Look at the garage door springs, cables, rollers, pulleys
and other door hardware for signs of wear. If you suspect
problems, have a qualified door mechanic make the repairs.
WARNING - SPRINGS ARE UNDER HIGH
TENSION. ONLY QUALIFIED PERSONS SHOULD ADJUST THEM.
Garage door springs, cables, brackets and other hardware
attached to the springs are under very high tension and, if
handled improperly, can cause serious injury or death. Only
a qualified professional or a mechanically experienced
person using the correct tools and carefully following the
manufacturer's instructions should adjust them. The torsion
springs ( springs above the door ) should only be adjusted
by a professional. Do not attempt to repair or adjust them
yourself.
Safety Cables
A restraining- or safety cable or other device should be
installed on the extension type spring to contain it if it
breaks. The energy released when a spring system fails is as
much as a .44 Magnum bullet at point blank range. The
consequences can be lethal.
Never remove, adjust or loosen the screws on the bottom
corner of the door. The bracket is connected to the spring
by the lifting cable and is under extreme tension.
Lubrication
Lubricate the moving parts of the door at regular intervals.
Do not lubricate plastic parts like plastic rollers and
plastic idler bearings on the door before consulting the
owner's manual for the manufacturer's recommendations.
Door Balance
Periodically test the balance of the door
· Start with the door closed.
· If you have a garage door operator, use the release
mechanism so you can operate the door by hand when doing
this test.
· You should be able to lift the door smoothly and with
little resistance. It should stay open around three or four
feet above the floor ( Balance position - 300 to 1800 mm
from the
floor) If it does not, it is out of adjustment. Have it
serviced by a qualified door mechanic.

Gate Automation
Automatic gates form an important part of
perimeter security. Consequently, the emphasis
in the design of gate automation products,
particularly in this country, focuses more on
security than convenience. This is important to
stress as many systems are based on European and
American designs where the convenience rather
than security is the overriding Factor.
Such (imported) systems may not allow for
important provisions such as mains power failure
back up which, in the South African context, is
necessary given the nature of local criminal
modus operandi, electrical storms and electrical
grid downtime which are not uncommon in many
parts of South Africa.
Speed and mode of
operation
An inherent potential security problem occurs
when the gate is open or in operation, as it
then creates the biggest hole in a perimeter
security system. Both the speed and mode of
operation of the automatic gate becomes
important. It is not uncommon for criminals to
use the opportunity before the gate closes to
enter the premises. What is required is a fast
moving gate, which closes the moment a vehicle
has passed through the entrance.
Safety
A critical requirement of any access automation
system is safety. Unfortunately, using safety
beams, inductive loops and anti-crushing
mechanisms built into the motor to make the
system safe, can aid any would-be intruder to
override the system when in operation. For
instance, if the vehicle has passed through the
entrance, by blocking the beam or physically
obstructing the gate before it starts to close,
will, as designed for safety purposes, prevent
the gate from closing and expose the entrance to
infiltration. It becomes a Catch 22 situation
and therefore when designing the access
automation system, safety factors vs security
requirements must be carefully balanced.
Selecting gate motors
In the same way that it is important to select
the correct tool for a job, so too must the
correct gate motor be chosen during automation
of a gate. Too often price dictates a purchase.
This is certainly the case when gate operators
are installed in commercial and industrial
applications. It is easy to under-estimate how
hard a gate motor in a commercial or industrial
installation might have to operate, where:
* The frequency of operation is typically
very high, resulting in problems such as
over-heating and excessive wear and tear.
* The average industrial gate is large and of
heavy construction and difficult to move.
* Gates in these applications are often abused.
Besides vehicles knocking into the gate, the
running conditions deteriorate leading to undue
stress being placed on the automation.
Preventative maintenance is often neglected in
the gate automation industry.
Reliable installation
crucial
How is a reliable installation guaranteed when
automating an existing sliding gate
installation? The first thing is to make sure
that the mechanical gate is correctly installed.
* The gate must have suitable mechanical end
stops, which can withstand the full momentum of
the gate particularly when driven under full
power of the motor.
* The gate should be properly balanced. Not
only must it be perfectly balanced vertically,
by the top guide rollers, but it must also be
balanced horizontally so that it slides open or
closed with equal force.
* Due care must be taken to ensure that the
gate slides as smoothly and lightly as possible.
The solution to the problem of a badly running
gate is not by installing a stronger motor.
Remember also, that in the event of a system
failure or emergency situation, an average
person must be able to slide the gate open with
relative ease.
There are also three factors to consider when
measuring up a sliding gate in order to select
the correct operator:
1. The physical mass of the gate.
Depending on the speed of the operator this
yields a measure of the momentum in the system
and determines the strength and size of the
operator gearbox.
2. The pull force required to move the gate.
This is a measure of the rolling friction in the
system and determines the power of the operator
motor required.
3. The duty cycle of the installation. In
an industrial application it is critical to know
how often the system is required to operate.
Besides the accelerated wear and tear, many
systems are susceptible to overheating and
consequential thermal shutdown in multiple usage
applications.
Make sure that the specifications of the sliding
gate operator under consideration fall within
these parameters. Secondly, bear in mind the
downtime cost implication if a product of
inferior quality fails. A good quality product
might cost more up front, but it is a better
long-term investment. 'You get what you pay
for!'

The new A10 operator is in a class of its own,
using a high-torque 3-phase motor and custom
designed frequency inverter to provide a fully
speed-controlled system capable of moving
industrial gates weighing up to 2 tons. On gates
up to 1000kg the normal operating speed is a
swift 16metres per minute. On lighter gates,
thanks to the frequency inverter this speed can
be increased to 30m/minute.
The unit can be operated almost continuously
when fitted with an optional cooling fan. Power
failure protection for the A10 is achieved by
simply adding an innovative DC converter module
with standby battery.
