The Most Dangerous Escalator In Europe
- Escalator Malfunction:
- Fans' weight increased motor load, causing it to accelerate uncontrollably.
-
Safety sensors detected the abnormal speed increase.
-
Emergency Measures Activated:
- Power was immediately cut from the motor.
-
Main brake engaged to stop the escalator, but failed due to insufficient force.
-
Braking Failure:
- Manufacturer's specification: 100% stopping power; actual braking force: only 37%.
-
The weakened brake could not counteract the massive strain and acceleration.
-
Auxiliary Brake Triggered:
- Escalator speed exceeded 20%, activating a secondary emergency brake.
-
Steel wedges were driven into a disc on the drive shaft.
-
Tampering Discovered:
- Investigators found that one of the two auxiliary brake wedges was disabled.
-
Plastic straps had been tied around this wedge, rendering it ineffective.
-
Human Error Identified:
- Someone physically tampered with the safety system to disable part of the brake mechanism.
