How to Maintain and Troubleshoot Common Escalator Problems

In a rapidly developing city like Dubai, escalators are essential to the infrastructure of malls, commercial buildings, metro stations, and airports. These systems transport thousands of people every day and must operate reliably without interruption. To ensure their long-term performance and safety, routine maintenance and proper troubleshooting are key.

As a trusted service provider in Dubai, Rona Elevators offers insights into common escalator problems and effective ways to manage them—helping property managers, technicians, and building owners stay ahead of costly breakdowns and safety issues.

Why Escalator Maintenance Matters

Regular escalator maintenance isn’t just about compliance—it directly impacts:

• Passenger safety
• System longevity
• Operational cost-efficiency
• Uninterrupted service

In a high-traffic environment like Dubai, poorly maintained escalators can lead to significant disruptions, customer dissatisfaction, or even legal liability.

Common Escalator Problems and How to Fix Them

1. Step Misalignment or Skirt Obstruction

Problem:
Misaligned steps or objects trapped in the skirt panel can cause jerky movements or stoppage.

Maintenance Tip:

• Clean the comb plates and skirt areas regularly.
• Inspect steps for signs of uneven wear or deformation.

Troubleshooting:

• Realign or replace misaligned steps.
• Use skirt brushes or guards to prevent debris entrapment.

2. Unusual Noises During Operation

Problem:
Grinding, squeaking, or rattling noises may signal worn components.

Maintenance Tip:

• Lubricate moving parts (chains, rollers, bearings) at regular intervals.
• Ensure escalator handrails and chains are tensioned correctly.

Troubleshooting:

• Isolate the noise source.
• Replace damaged chains or realign misfitting components.

3. Handrail Slippage or Lag

Problem:
The handrail moves at a different speed from the steps, which poses a serious safety risk.

Maintenance Tip:

• Check and adjust handrail drive systems regularly.
• Keep the handrail track clean and properly lubricated.

Troubleshooting:

• Tighten or replace slipping handrails.
• Calibrate synchronization between the step chain and handrail drive.

4. Frequent Tripping of Safety Switches

Problem:
Safety switches trip due to obstructions, electrical faults, or poor calibration.

Maintenance Tip:

• Conduct monthly inspections of brake systems and safety sensors.
• Remove any foreign material near sensors and switches.

Troubleshooting:

• Test the control panel for error codes.
• Reset or replace faulty switches after identifying the root cause.

5. Power Fluctuations or Electrical Failures

Problem:
Escalators stop working unexpectedly due to voltage drops or control system failures.

Maintenance Tip:

• Inspect circuit breakers and power supplies routinely.
• Ensure grounding systems are intact.

Troubleshooting:

• Use diagnostic tools to trace faults in control panels or power inputs.
• Replace worn-out relays, contactors, or wiring.

Proactive Maintenance Practices

To minimize the risk of operational failures, follow these preventive measures:

• Daily Checks
  Visually inspect escalators for signs of damage, obstruction, or odd sounds.
• Monthly Servicing
  Engage professional technicians like Rona Elevators to check mechanical and electrical systems.
• Quarterly Safety Testing
  Ensure that safety devices such as emergency stop buttons, anti-slip features, and handrail speed regulators are functioning properly.
• Annual Deep Inspection
  A comprehensive system check—including drive units, gear motors, and control panels—should be performed annually.
