How to Use This Calculator

Enter the Number of Elevators sharing the machine room.
Select Elevator Type (geared, gearless traction, or hydraulic).
Input Rated Load (kg) and Rated Speed (m/s) for each elevator.
Enter Hoistway Width and Depth (m) to calculate machine room footprint.
Review Room Area (m2) required — add 15-20% for code-required maintenance clearances.

How the result changes with Rated load (kg)

Room area (m²): Required machine room floor area.
Room area (sq ft): Machine room area in square feet.
Room width (m): Recommended room width.
Room depth (m): Recommended room depth.
Min. ceiling height (m): Minimum ceiling height for equipment clearance (code min 2.13 m / 7').
Motor power per unit (kW): Estimated motor power per elevator.
Ventilation needed (BTU/hr): Heat dissipation requiring machine room ventilation or cooling.
Area ratio (room:hoistway): Machine room area as multiple of combined hoistway area.

Identify Input Parameters

Number of elevators = 2, Elevator type = 1, Rated load (kg) = 1600, Rated speed (m/s) = 2.5 = 6 input(s) provided
Calculate Room area
Room area = roomWidthRounded * roomDepthRounded
44.8 = 44.8
Calculate Room area
Room area = roomWidthRounded * roomDepthRounded
482.7 = 482.7
Calculate Room width
Room width = ceil(roomWidth * 10) / 10
7.6 = 7.6
