What is likely happening
Escalators stop when a safety device trips, often from debris in the comb plates, a skirt switch, or a handrail issue. Noise usually points to steps, chains or bearings.
What you can safely check
- Look for debris at the top and bottom comb plates.
- Barricade before restarting if the cause is not obvious.
What an inspector will look at
- Step and chain condition
- Safety devices and switches
- Comb plates and skirts
- Brake
Does this affect compliance?
Escalators are on periodic inspection cycles in most jurisdictions.
When it becomes urgent
Keep it stopped and barricaded if anyone was hurt or a step is damaged.
