The general formula for elevator HP is:

Unbalanced Load(lbs) x Speed(fpm) divided by 33,000 x Efficiency (efficiency is expressed thusly: 100% efficiency = 1, 60% efficiency = .6, etc.)

as noone installs 2 speeds and havent for MANY years....why dont you go and look at the motor data plate on the machine...or are you a sales rep who cant get off his fat arse and want someone else to do the work.
