How to Use This Calculator

Enter the maximum load (lb) — the heaviest item the hoist will lift.
Set the required lift height (ft) to determine rope and drum requirements.
Input cycles per hour — how many full lifts and lowers occur in one hour of operation.
Enter the desired lift speed (ft/min) from your application requirements.
Read Rated capacity (lb) and Duty class (H2–H5) to specify the correct hoist, and check Motor (HP) for electrical planning.

What each input means

Identify Input Parameters
4 parameters
Max load (lb) = 2000, Lift height (ft) = 20, Cycles per hour = 10, Lift speed (ft/min) = 16 = 4 input(s) provided
Calculate Rated capacity
2000 = 2000
Calculate Duty class
3 = 3
Calculate Motor
Motor = round((requiredCapacity * liftSpeedFpm) / 33000 * 100) / 100
0.97 = 0.97
