How to Use This Calculator

Enter Rise height (mm), Platform width (mm), and Platform depth (mm).
Set Rated capacity (kg), Type (1=unenclosed, 2=enclosed), and Drive (1=hydraulic, 2=screw, 3=rack).
Review Rise code compliant (1=yes) and ADA size compliant (1=yes).
Use Travel time (seconds) and Motor power (HP) to inform your decision.

What each input means

Rise height (mm): Vertical distance the lift must travel.
Platform width (mm): Clear width of the lift platform. ADA minimum: 914 mm (36 in).
Platform depth (mm): Clear depth of the lift platform. ADA minimum: 1219 mm (48 in).
Rated capacity (kg): Weight capacity. ASME A18.1 minimum: 340 kg (750 lbs).
Type (1=unenclosed, 2=enclosed): 1 = Unenclosed (max 1.5 m rise), 2 = Enclosed vertical platform lift (max 4.27 m).
Drive (1=hydraulic, 2=screw, 3=rack): 1 = Hydraulic (fastest), 2 = Screw drive (smoothest), 3 = Rack-and-pinion.

Rise code compliant (1=yes): 1 if rise height is within ASME A18.1 limits for the selected lift type, 0 if exceeded.
ADA size compliant (1=yes): 1 if platform meets ADA minimum clear dimensions.
Travel time (seconds): Time for one full travel from bottom to top.
Motor power (HP): Required motor horsepower for the drive system.
Shaft width needed (mm): Minimum enclosure/shaft internal width.
Shaft depth needed (mm): Minimum enclosure/shaft internal depth.
Pit depth (mm): Required pit depth below lower landing.
Est. cost low ($): Lower bound of estimated equipment cost (USD).
Est. cost high ($): Upper bound of estimated equipment cost (USD).

Identify Input Parameters
4 parameters
Rise height (mm) = 1500, Platform width (mm) = 914, Platform depth (mm) = 1219, Rated capacity (kg) = 340 = 6 input(s) provided
Calculate Rise code compliant
1 = 1
Calculate ADA size compliant
1 = 1
Calculate Travel time
Travel time = (riseHeightMm / 1000) / speedMps
10 = 10
Calculate Motor power
Motor power = motorPowerKW * 1.341
1.56 = 1.56
