Pre-Installation Assessment (Before You Install the Motor)
Before installing any type of gate automation, a thorough site assessment is crucial. Proper evaluation ensures the automation system performs reliably and safely long-term.
Check Gate Structure and Materials
Your swing gate must be strong enough to support an automated system. Consider:
-
Gate weight and width relative to your chosen motor.
-
Material type: Steel, aluminium, wrought iron, or timber.
-
Gate frame alignment: Should not sag, bend, or twist.
-
Hinges: Check the condition of both the top and bottom hinges.
If the gate has excessive movement on the hinges, the motor will strain, leading to eventual failure. Reinforce or replace weak points before automation installation.
The Importance of Top & Bottom Hinges in Swing Gate Automation
The hinges are the backbone of a swing gate. They determine how smoothly your gate moves, how much motor torque is needed, and whether your automation system will last for years.
Why Top & Bottom Hinges Matter
Top and bottom hinges:
-
Maintain the gate’s vertical alignment
-
Support the full load of the gate
-
Control the swing arc
-
Prevent unwanted wobble or sagging
-
Reduce strain on the gate motor
Incorrect hinge alignment is one of the most common causes of motor failure in Swing Gate Automation systems.

Ensuring Proper Hinge Alignment
To verify proper alignment:
-
The vertical centreline between the top and bottom hinge should be perfectly straight.
-
Use a spirit level or digital laser level.
-
Ensure the gate does not scrape the ground at any point during the full swing arc.
-
Adjust hinge tension (for adjustable hinges).
If alignment is off, the gate will require more force, causing overheating or burnout of the motor.
Choosing the Right Motor for Swing Gate Automation
Different motors suit different property types and gate weights. Choosing the wrong system will reduce performance and lifespan.
Types of Swing Gate Motors
-
Linear Actuator (Ram) Motors
Best for residential gates; mounted between gate and post. -
Articulated Arm Motors
Suitable for wide or heavy gates; ideal when space around the hinge is limited. -
Underground Motors
Highly aesthetic; ideal for premium finishes and heavy gates. -
Hydraulic Swing Motors
Designed for demanding or commercial applications.
Motor Selection Considerations
Evaluate:
-
Gate weight
-
Gate width
-
Number of daily cycles
-
Environment (coastal, dusty, windy)
-
Power source: 240V AC, 24V DC, solar options
-
Safety features (obstruction detection, slow stop/start)
A precise selection guarantees optimal swing speed, torque, and longevity.
Step-by-Step Guide to Installing Swing Gate Automation
Below is a detailed overview of the installation process, focusing on systems using top and bottom hinges.
Step 1: Install or Reinforce Hinges
Before any motor is attached:
-
Inspect hinge welds or bolts for strength.
-
Align the gate vertically and horizontally.
-
Ensure the gate swings freely by hand.
-
Lubricate hinges to reduce future friction.
If you detect sagging or lateral movement, correct this first.
Step 2: Mark Motor Mounting Points
Each motor type comes with specific bracket positioning. General rules include:
-
Ensure the motor’s opening arc matches the gate’s intended arc.
-
Align brackets according to manufacturer measurements (often A-B dimensions).
-
Ensure the motor sits level and parallel to the gate frame.
Precision is crucial: even a 5 mm misalignment can cause noise or jerky movement.
Step 3: Position the Motor Brackets
Using a welder or heavy-duty screws:
-
Attach the post bracket firmly to the gate post or pillar.
-
Attach the gate bracket to the gate frame.
-
Use metal backing plates if working with thin posts.
Double-check measurements before securing permanently.
Step 4: Install the Motor Arms
Attach the motor arms to the mounted brackets:
-
Verify that each arm has full range of movement.
-
Test opening and closing manually (with power off).
-
Ensure the motor does not bind, twist, or overextend.
Manual movement tests are essential before electrical wiring begins.
Step 5: Run Electrical Cabling
For Australian installations:
-
Use UV-rated conduit for outdoor wiring.
-
Ensure cabling complies with Australian electrical safety standards.
-
Keep wiring protected from flooding, pests, and accidental impact.
If unsure, consult a licensed electrician—especially for 240V motor systems.
Step 6: Connect Control Box and Set Limits
Once cabling is connected:
-
Mount the control box on a nearby wall or post.
-
Connect motor leads to their dedicated ports.
-
Set open and close limits using control board programs.
-
Adjust soft start/stop settings for smooth operation.
-
Test the obstruction detection sensitivity.
Limit-setting ensures the gate stops precisely where you want it.
Step 7: Install Safety Accessories
For compliance and safe operation:
-
Photocell sensors
-
Flashing warning light
-
Emergency release key
