Escalator Capacity Calculator
Estimate passenger throughput and indicative drive power of an escalator from step width, nominal speed, lift height and design load.
How to Use the Escalator Capacity Calculator
- Enter step width in mm.
- Enter nominal speed in m/s.
- Enter vertical lift and design load.
- Click Calculate.
使用场景
- •Retail / metro / airport capacity planning.
- •Quick sanity checks on supplier datasheets.
- •Teaching vertical-transport design.
公式
Steps/min = (speed × 60) / 0.4. Capacity (pers/h) ≈ steps/min × persons/step × 60 × 0.8 (usage factor).
常见问题
Why 0.8 usage factor?
Real occupancy rarely fills every step. EN 115 and ASME A17 both apply a diversity factor around 0.75–0.85.
Is motor power exact?
No — it is an order-of-magnitude estimate. Real escalators add friction, efficiency and safety margins.
