Maintenance Perspective: Why Underground Motors Fail More Often Than Swing Arm Motors
Swing gates are a popular choice for landed properties in Singapore, and homeowners often choose between underground motors and swing arm motors to automate them. While both systems can provide reliable operation, underground motors are more prone to failure compared to swing arm motors. The difference lies in how they are installed, the environment they operate in, and the maintenance challenges they present.
Underground Motors: Hidden but Vulnerable
Underground motors are installed beneath the driveway, concealed in a housing near the gate hinge. This design offers a clean, aesthetic look, but it also exposes the motor to harsher conditions.
Why Underground Motors Fail More Often
Moisture exposure: Being buried underground, these motors are constantly exposed to rainwater, soil moisture, and humidity. Even with waterproof housings, seals can wear out over time, allowing water to seep in.
Drainage issues: If the housing does not drain properly, water can accumulate and damage electrical components.
Difficult access: Servicing underground motors requires opening the housing and sometimes digging, which makes routine checks less frequent. Problems often go unnoticed until the motor fails completely.
Heat and corrosion: Underground environments trap heat and moisture, accelerating wear on metal parts and electrical circuits.
Maintenance Requirements
Regular inspection of seals and drainage systems.
Checking for water accumulation inside the housing.
Professional servicing to clean and lubricate internal components.
More frequent maintenance compared to swing arm motors.
Swing Arm Motors: Practical and Reliable
Swing arm motors are mounted above ground on the gate posts, with arms that push or pull the gate open. They are visible, but far easier to maintain.
Why Swing Arm Motors Last Longer
Accessible location: Because they are mounted above ground, technicians can easily inspect, clean, and repair them.
Less exposure to moisture: Swing arm motors are not buried, so they are less vulnerable to water damage.
Simpler design: Fewer seals and drainage requirements mean fewer points of failure.
Routine maintenance is easier: Homeowners can visually check for rust, loose bolts, or wear without specialized tools.
Maintenance Requirements
Lubricating the motor arms and hinges.
Checking bolts and brackets for tightness.
Inspecting electrical connections for wear.
Annual servicing to ensure smooth operation.
Conclusion
From a maintenance perspective, underground motors fail more often than swing arm motors because they are exposed to moisture, drainage problems, and difficult servicing conditions. Swing arm motors, on the other hand, are easier to access, simpler to maintain, and generally more reliable over time.
For most landed property owners in Singapore, swing arm motors are the practical choice if you want a system that is durable and easier to maintain. Underground motors remain an option for those who prioritize aesthetics, but they require more frequent professional servicing to stay reliable.
