The size of the hoist is determined by the load 1. What are the operating conditions? 5. Do the loads need to be lifted and lowered with
spectrum, average operating time per working day, 2. What is the specified safe working load? great accuracy?
load capacity and reeving. 6. Is horizontal load travel necessary?
3. To what height must the load be lifted?
4. What is the required lifting speed? 7. How is the hoist to be controlled?
The load spectrum
(in most cases estimated) can be evaluated
according to the definitions below:

Rmax1 = (Q+mbb) · f1 / 100% = (2500 kg + 21 kg) · 39,7% / 100% = 1001 kg
Rmax2 = mc · f2 = 312 kg · 0,36 = 112 kg
Rmax = Rmax1 + Rmax2 = 112 kg + 1001 kg = 1113 kg
