Elevator Door Cycle Count at 99% door operator uptime: a worked example

This scenario runs the elevator door cycle count calculation on the strong side: 99% door operator uptime, with every other input held at its documented default. a quality or maintenance engineer needs to plan door operator endurance, test, or replacement assumptions

The inputs for this scenario

  • Door open/close events per test cycle: 2 open/close cycles (unchanged)
  • Scheduled door endurance test cycles: 18,000 cycles (unchanged)
  • Door operator uptime: 99 % (raised for this scenario; the documented default is 94)
  • Door cycle acceptance yield: 98 % (unchanged)

Working through the calculation

  • Applying the documented formula (Gross door cycles = door openings per cycle × available door test cycles) to the inputs above produces each figure below.
  • At this operating point the engine returns 34,927 door cycles for accepted door cycles, the number this scenario is built around.
  • At this operating point the engine returns 36,000 door cycles for gross door cycles.
  • At this operating point the engine returns 360 door cycles for door cycles lost to downtime.
  • At this operating point the engine returns 713 door cycles for door cycles held for adjustment.

How this compares with the baseline

  • Against the tool's baseline example, where door operator uptime sits at 94% and the headline result is 33,163 door cycles, this scenario comes in 5.32% above the baseline at 34,927 door cycles.
  • Use it when planning a door endurance test campaign or reconciling how many validated cycles a test cell produced against its schedule. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • Accepted door cycles: 34,927 door cycles (headline result)
  • Gross door cycles: 36,000 door cycles
  • Door cycles lost to downtime: 360 door cycles
  • Door cycles held for adjustment: 713 door cycles
