Gate Automation & Motors on the Sunshine Coast
If your existing gate binds or drags when you push it by hand, adding a motor will not fix that. It will find the problem faster and break something.
Automating an existing gate — the honest test
Push it open by hand, slowly, through its whole travel. Does it bind, drag, catch or need a lift anywhere?
If so, that gate is not ready to be automated. A motor applies far more force than you do, thousands of times a year, without any of the judgement you apply when something feels wrong. It will find the binding point and destroy something — the gate, the post, or eventually itself.
What has to be sound before automation is worth spending money on:
- **Hinges, posts and wheels**, which carry the load. Posts adequate for occasional manual use often are not adequate once powered. - **A clear travel path** — a full arc for a swing gate, or a clear run of roughly the gate's own width for a sliding gate. - **Consistent ground clearance** along the whole travel. - **Sound metal.** Near the coast, we specifically check for **hinge posts rusted out from the inside** — a post that looks fine at eye level can be hollow at the base.
Sizing: the two numbers that matter
**Gate mass.** A common residential sliding operator is rated to **500 kg maximum** with a **17 kgf rated push force**. Larger industrial units handle 1,000 kg.
**Duty cycle**, which is the one people skip. Published specifications for a common operator: **150 operations per day maximum at a 50 per cent duty cycle**. The low-voltage version of the same unit drops to **55 operations per day at 20 per cent duty cycle** — which matters if you are going solar on a busy entrance.
A motor running near its ceiling every day generates heat it cannot shed, and the windings degrade. The failure is gradual: slower, then stopping mid-travel, then nothing.
Gate speed is worth asking about too. Published figures run **22 metres per minute at low resistance, dropping to 18 at rated force**. On a long gate that is the difference between waiting in your driveway and not.
Battery backup comes as standard
Most residential operators here are **12 or 24 volt DC** with an internal battery — mains charges it, the battery runs the motor. That architecture is exactly why they keep working through a blackout.
Published figures for one operator on a 7 Ah battery: **44 operations in half-day standby, 35 over a full day**, with the manufacturer noting that assumes a four metre gate and **excludes safety beams**, which draw standby current. Fit beams, as you should, and expect fewer.
Who may legally connect it
Under Queensland's *Electrical Safety Act 2002*, equipment operated above **extra low voltage** — above 50 volts AC or 120 volts ripple-free DC — is electrical equipment, and connecting supply wiring to it is electrical work requiring a licensed electrician working for a business with an **electrical contractor licence**.
Useful distinctions:
- **Plugging a gate supply into an existing outlet is not electrical work.** Installing a new outlet is. - **Mounting the motor is not electrical work.** Making the connection is. - A genuinely low-voltage motor on a plug-pack or solar sits outside that definition. A hardwired transformer does not.
You are entitled to a **Certificate of Testing and Compliance** stating the electrical contractor licence number after any mains work. Ask for it.
Costs
Australian retail supply pricing, including GST, is a useful anchor:
- Sliding operators for 400–500 kg gates: **$693 – $935** - Industrial sliding, 1,000 kg: around **$1,649** - Single swing operators: **$1,190 – $1,535** - Double swing kits: **$1,359 – $1,599**
Installed figures run wider — motor supply and install commonly quoted at $600 to $3,500, with labour $1,000 to $5,000 depending on complexity and whether power has to reach the gate.
Warranty, and what it does not cover
Product warranties on common brands run **24 months**, with **batteries at six months** because they are consumables. One brand is 12 months overall.
The exclusions are what matter here: both major brands void cover for **lightning and power surges**, **corrosion of metal parts**, and **insect infestation**. One also excludes water and moisture damage and inadequate cable glanding or sealing of the control box.
Look at that list against a coastal Queensland summer. Salt, storms and ants are the three most likely killers, and none of them is covered — which is the argument for correct earthing, sealed enclosures, 316 fixings and a service schedule rather than for relying on the warranty.
Why choose us for gate automation & motor installation
- Straight answer on whether your existing gate is worth automating
- Motor sized on gate mass and real daily cycles, not the price list
- Corroded hinge posts checked, since coastal exposure hollows them out
- Certificate of Testing and Compliance for any 240V connection
- Sealed, glanded and earthed properly, because warranty excludes the rest
Gate Automation & Motor Installation — common questions
Can you automate my existing gate?
Push it open by hand through its full travel first. If it binds, drags, catches or needs a lift anywhere, automating it will not fix that — a motor applies far more force than you do, thousands of times a year, and will find that point and break something. Hinges, posts, wheels, clear travel and consistent ground clearance all need to be sound. Near the coast we also check for hinge posts rusted out from the inside.
What size motor does my gate need?
Two numbers decide it: gate mass and daily cycles. A common residential sliding operator is rated to 500 kg with 17 kgf push force and a maximum 150 operations per day at 50 per cent duty cycle; industrial units handle 1,000 kg. Duty cycle is the one people skip — running near the ceiling daily generates heat the motor cannot shed, degrading the windings and killing it early.
How much does a gate motor cost?
Australian retail supply pricing including GST: sliding operators for 400 to 500 kg gates run $693 to $935, an industrial 1,000 kg unit around $1,649, single swing operators $1,190 to $1,535, and double swing kits $1,359 to $1,599. Installed figures are wider — motor supply and install commonly $600 to $3,500, with labour $1,000 to $5,000 depending on complexity and whether power has to reach the gate.
What happens to my gate in a power cut?
It keeps working, for a while. Most residential operators are 12 or 24 volt DC with an internal battery — mains just charges it. Published figures for one operator on a 7 Ah battery are 44 operations in half-day standby or 35 over a full day, and the manufacturer notes that assumes a four metre gate and excludes safety beams, which draw standby current. There is also a key-operated manual release we show you at handover.
Do I need a licensed electrician?
For a 240 volt connection, yes. Under the Electrical Safety Act 2002, equipment operated above extra low voltage — 50 volts AC or 120 volts ripple-free DC — is electrical equipment, and connecting supply wiring to it is electrical work. The business must hold an electrical contractor licence and you are entitled to a Certificate of Testing and Compliance showing that number. Plugging into an existing outlet is not electrical work; installing a new outlet is.
How fast should my gate open?
Published figures for a common operator run 22 metres per minute at low resistance, dropping to 18 at rated force. On a long gate that is genuinely the difference between waiting in your driveway and not. If speed matters to you — and on a busy entrance it usually does — the answer is a faster operator rather than a bigger one, and it is worth raising before purchase rather than after.
Will a new motor work with my existing remotes?
Generally only if you stay with the same brand and a compatible receiver. Receivers are brand-specific and use rolling codes, so changing manufacturer usually means new remotes for everyone. Worth factoring into a replacement quote if you have several transmitters in circulation. Receiver capacity varies too — one brand holds 27 transmitters, another 500 button codes.
What does the warranty actually cover near the coast?
Less than you would like. Product warranties run 24 months on common brands, with batteries at six months as consumables, and one brand at 12 months overall. Both major brands exclude lightning and power surge damage, corrosion of metal parts, and insect infestation — which on the Sunshine Coast is essentially the three most likely causes of failure. Correct earthing, sealing and servicing matter more than the warranty document.
