How to Use This Calculator
  1. Enter Car width (mm), Car depth (mm), and Car height (mm).
  2. Set Number of floors, Floor-to-floor height (mm), and Door type (1=CO, 2=SO-2, 3=SO-3).
  3. Adjust Car speed (m/s) as needed.
  4. Review Hoistway width (mm) and Hoistway depth (mm).
  5. Use Hoistway area (m²) and Pit depth (mm) to inform your decision.

What each input means

Car width (mm)
Inside width of the elevator car platform.
Car depth (mm)
Inside depth of the elevator car platform.
Car height (mm)
Inside height of the elevator car (floor to ceiling).
Number of floors
Total number of floors served.
Floor-to-floor height (mm)
Typical floor-to-floor height.
Door type (1=CO, 2=SO-2, 3=SO-3)
1 = Center opening, 2 = Side opening 2-panel, 3 = Side opening 3-panel.
Car speed (m/s)
Elevator rated speed, affects pit depth and overhead requirements.

What each result means

Hoistway width (mm)
Required inside width of the hoistway shaft.
Hoistway depth (mm)
Required inside depth of the hoistway shaft.
Hoistway area (m²)
Cross-sectional floor area of the hoistway.
Pit depth (mm)
Required pit depth below the lowest landing per ASME A17.1.
Overhead clearance (mm)
Required clearance above the highest landing.
Total hoistway height (mm)
Full hoistway height from pit floor to machine beam.
Total travel (mm)
Vertical distance between lowest and highest landings.
Counterweight width (mm)
Estimated counterweight frame width.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Car width (mm) = 2100, Car depth (mm) = 1600, Car height (mm) = 2400, Number of floors = 10 = 7 input(s) provided
  2. Calculate Hoistway width
    Hoistway width = carWidthMm + 2 * sideGuideClearance + cwWidthMm + cwGap
    2930 = 2930
  3. Calculate Hoistway depth
    Hoistway depth = carDepthMm + rearClearance + doorMechDepthMm + sideGuideClearance
    1900 = 1900
  4. Calculate Hoistway area
    Hoistway area = (hoistwayWidthMm / 1000) * (hoistwayDepthMm / 1000)
    5.57 = 5.57
  5. Calculate Pit depth
    Pit depth = max(pitMinMm, bufferStrokeMm + pitRunbyMm + 600)
    1200 = 1200
