Problem statement: Frequent breakdown of escalators due to ineffective cleaning process

Impact of problem: Created dissatisfactions and inconvenience for the customers. A broken-down escalator can also create a negative perception of the mall’s services.

Root cause analysis
  • There was no possibility of overload causing the escalators to trip
  • Escalator preventive maintenance was completed on time and in accordance with the OEM schedule
  • The escalator speed suddenly decreases due to dust
  • Stain marks were noticed because of inadequate manual cleaning
  • The escalator motor pit’s dust particles were visible
  • Every time there is a breakdown, the sensors need to be cleaned
  • According to the breakdown history, weekends were the days when breakdowns were most prevalent.
  • Upon examining the cleaning schedule of the escalator, it was discovered that weekend breakdowns continued to occur even with daily cleaning frequency.
Mitigation plan
  • Controlling the tiny dust particles at the footstep level.
  • Because manual cleaning proved ineffective, a machine cleaning procedure was to be explored.

The correct machine needed to be identified, especially for trapping and removing minute dust particles.

Corrective actions
  • The escalator cleaning machine was purchased to clean escalators.
  • The vacuum cleaner for escalators has a wet and dry mode vacuum wand attachment.
  • One escalator had a daily cleaning frequency at first with the machine, one at a time. After closely observing the cleaning and analysing the results, it was found that the tripping of escalators and slowing down of machinery had been reduced.
  • Later, the frequency of escalator machine-cleaning was changed to once per week for all eight escalators, particularly before the weekend.
Impact analysis
  • Escalator downtime has decreased.
  • Decrease in the escalator’s operating expenses
  • People’s confidence in using escalators has increased
  • As a result of machine cleaning, the sensor and spare part ageing on escalators improved.
  • Escalators were made more hygienic for users.
  • Presenting a spotless and orderly escalator to consumers as a best practice
  • Had a positive impact on business and attracted footfall.
