Why Do Escalator Steps Have Teeth?

Summary by Krater

This video investigates the October 23, 2018 escalator accident at the Repubblica metro station in Rome, analyzing the engineering of escalators, how safety mechanisms failed, and the institutional neglect that caused 24 injuries.

From the video

Answers: Why did the escalator collapse in Rome and how do escalators work?

• escalator mechanics
• Rome metro accident
• regenerative braking
• escalator safety systems
• mechanical failure investigation

What it concludes

• The 2018 escalator accident at Repubblica station in Rome injured 24 people due to a combination of mechanical overload, disabled safety brakes, and falsified maintenance records.
• Modern downward escalators can act as generators, converting the passenger weight and motor resistance into electricity.
• Negligent maintenance and compromised safety systems turned preventable mechanical failures into a catastrophic accident.
• Regular and rigorous maintenance of safety brakes and error logs is essential to prevent catastrophic escalator failures.
