Many users assume that once a barrier gate is installed and operating normally, no further attention is needed. However, daily exposure to rain, dust, and frequent use can silently degrade its performance. Without routine maintenance, issues such as increasing noise, sluggish operation, motor burnout, or limit system failure can arise, shortening the lifespan of a gate.

With just 10 minutes and a few key techniques, you can significantly extend your barrier gate’s service life. JUJIANG GIANT provides a clear, step-by-step guide to motor maintenance and lubrication, suitable even for non-professionals.

professional support to ensure your barrier gate operates flawlessly.

Why Regular Maintenance is Essential

A barrier gate relies on three core components: the motor, transmission system, and limit mechanism. Over time:

  Gears and shafts lose lubrication → accelerated wear, increased noise.

  Limit blocks accumulate dust or loosen → inaccurate positioning, collisions.

  Motor terminals oxidize → poor contact, reduced motor power.

These factors account for over 80% of mechanical failures.

Maintenance and Lubrication Procedures

Based on the JUJIANG GIANT barrier gate ,we recommend the following standardized procedure:

  Tools: Lithium-based grease or low-temperature lubricant, screwdriver, cloth, brush, insulating gloves.

  Power Off: Always disconnect AC 220V or DC 12V before maintenance.

  Lubrication Points: Gear mesh, shaft, sliding surfaces of mechanical limit blocks.

  Lubricant: Use lithium-based grease; avoid penetrating spray oils.

  Frequency: Every six months for standard use, every three months for high-frequency use.

  Motor Check: Ensure terminals are secure.

Overheat Protection: If “HE” appears on the control board, stop and allow cooling.

Precautions:

Never wash the motor area with water or high-pressure air.

Never manually force the arm while powered.

Do not lubricate a hot motor immediately.
