How to Use This Calculator
- Select Step Width (600, 800, or 1000 mm) based on the installation.
- Enter Speed (m/s) — typically 0.5 m/s for standard escalators.
- Set Vertical Rise (m) and Incline Angle (30 or 35 degrees).
- Enter Step Utilization (%) based on observed passenger loading patterns.
- Review Practical Capacity (persons/hr) vs. Theoretical Maximum to verify the escalator meets peak demand.
How the result changes with Speed (m/s)
| Speed (m/s) | Practical capacity (persons/hr) |
|---|---|
| 0.35 | 3,260 |
| 0.46 | 4,328 |
| 0.59 | 5,604 |
| 0.71 | 6,662 |
What each input means
- Step width
- 0 = 600 mm (single file), 1 = 800 mm (single + passing), 2 = 1000 mm (two abreast).
- Speed (m/s)
- Escalator travel speed (standard 0.5 m/s, max 0.65 m/s per EN 115).
- Vertical rise (m)
- Total vertical height from bottom to top landing.
- Incline angle (°)
- Escalator angle of inclination (30° standard, max 35° for rise < 6m).
- Step utilization (%)
- Fraction of steps occupied (60-80% typical, 100% = crush load).
What each result means
- Practical capacity (persons/hr)
- Realistic throughput at the specified utilization rate.
- Theoretical max (persons/hr)
- Maximum capacity if every step were occupied.
- Visible steps
- Number of steps visible on the incline.
- Total steps (including flat)
- Total step count including flat sections at top and bottom.
- Slope length (m)
- Total length along the incline from bottom to top.
- Horizontal run (m)
- Horizontal distance from pit edge to upper support.
- Motor power (kW)
- Estimated drive motor power requirement.
- Travel time (s)
- Time for a passenger to ride from bottom to top.
- Step width (mm)
- Nominal step width.
How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersStep width = 2, Speed (m/s) = 0.5, Vertical rise (m) = 5, Incline angle (°) = 30 = 5 input(s) provided
- Calculate Practical capacityPractical capacity = theoreticalCapacity * (utilizationPct / 100)4725 = 4725
- Calculate Theoretical maxTheoretical max = (pps * speed * 3600) / stepSpacing6750 = 6750
- Calculate Visible stepsVisible steps25 = 25
