 Selection criteria

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 ac-
cording to the definitions below:

1 Light The group is determined by the load spectrum and operating time.

Hoist units which are usually subject to very small Load spectrum Average operating time per working day in hours

loads. 1 Light 2-4 4-8 8-16 more than 16

The average operating time per working day is estimated or calculated as follows:
Operating time

2 · average hook path · no. of cycles/hour · working

Operating time/ time/day =
day =
60 · hoist speed

Operating time/ 2 · 3 · 20 · 8
= 2,66 hours
day = 60 · 6

For the medium load spectrum and an average daily operating time of 2,66 hours,
the table above shows group 2m. For a load capacity of 5 t and 4/1 rope reeving,
the following table indicates hoist size DR-Bas 5 - 5.
