Unless you
possess the power of teleportation (in which case we’d like offer our thanks
for reading our modest newsletter, oh visitor from another world), chances are
that you gain access to your property by means of a point of entry enclosed by
walls, or “gate” as we sometimes like to call it (as an interesting aside, the
word “gate” derives from the old Norse word gata,
meaning road or path). But, perhaps you only recently had the fence or wall
erected and it as yet sans gate, or
you have simply decided to automate an existing one. Then, dear reader, it is
important to know what kind of hardware you’ll need and what function it
performs, lest you end up with a gate that is either recalcitrant or, even worse, unsafe. Fortunately, we’ve
been in the gate automation business for going on 30 years and we’re
channelling that experience towards guiding you in any-gate related endeavours
that you may wish to undertake.
Here’s what
you’ll need:
Guide-rollers
Guide-rollers do
exactly what their name suggests, they guide the gate. In other words, the
guide-rollers – which are normally just two nylon rollers that rotate on shafts
– hold the gate vertically and prevent it from falling over which is, you know,
something you’d want to avoid if possible. For improved safety, we recommend
fitting additional support posts to prevent the gate from falling over should
the guide-rollers fail.
Anti-lift Brackets
Again, the job
description is more or less in the name here. Anti-lift brackets help prevent
unauthorised access to your property by ensuring that the gate can’t simply be
lifted off its track by some devious criminal/strongman combo (of course, most
gates are light enough not to require a strongman to lift it, hence the need
for anti-lift brackets).
Endstops
Endstops are
very important from a safety point of view and prevent your gate from
abandoning its track. Remember that there is always the chance, however remote,
that the gate will overrun its limits (and we’d like to point out here that
with our new generation of gate motors, the chance is even more remote since
the operator will always look for the origin magnet and will run the gate
slowly if it is not detected), and you don’t want the gate behaving like a
runaway train with nothing to stop it. CENTURION recommends installing
mechanical endstops that are sturdy (preferably welded onto the track) and do
not move even when subjected to considerable force.
Wheels
The movement of
your gate depends largely on the presence of a collection of spherical objects
that rotate about a shaft, or “wheels”. Keep in mind that the entire weight of
your gate will rest upon the wheels, so it’s important to keep them in a good
condition and rotating freely. They will also need to be compatible with the
profile of the rail. CENTURION stocks both U- and V-profile gate wheel kits, as well as the novel GateShox system which dramatically reduces noise in sliding gates. Over time, the rails of sliding gates can become corrugated and uneven from use, and GateShox help absorb the load through a spring system, resulting in a smoother ride and quieter operation.
Rack
If you’re
planning on automating your gate (and, let’s be honest, it’s the logical thing
to do), you’ll need a toothed rack fitted along the length of the gate to mesh
with the pinion of your gate motor. The setup works in an almost identical
fashion to the rack-and-pinion configuration found in the steering wheel
mechanisms of most cars and, depending on which operator you’re planning on
having installed, you’ll need either Raz, nylon angle or steel rack. Not sure
which one? Give us a call on +27 11 699 2481 for some friendly advice.
A Reliable Gate Motor
We previously
likened buying a new gate operator to selecting a new car. Considerations such
as the weight of the gate, maximum number of daily operations, push force and
duty cycle all need to be taken into account when choosing an automation
system. But, most of all, it’s important to ensure that you choose a gate motor
that will never leave you out in the cold, so to speak. CENTURION manufactures
a wide range of reliable swing and sliding gate motors for domestic, light
industrial and full industrial applications. Our operators are constructed from
only the most robust materials in accordance with the ISO9001 quality assurance
system, and carry a 24 month warranty.
