Selection criteria
The size of the hoist is determined by the load spectrum, average operating time per working day, load capacity and reeving.
1. What are the operating conditions? 2. What is the specified safe working load?
5. Do the loads need to be lifted and lowered with great accuracy?
3. To what height must the load be lifted?
6. Is horizontal load travel necessary?
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: The group is determined by the load spectrum and operating time.
Hoist units which are usually subject to very small loads and in exceptional cases only to maximum loads.

Operating time
The average operating time per working day is estimated or calculated as follows: Operating time/ day = Operating time/ day =
2 · average hook path · no. of cycles/hour · working time/day
=
60 · hoist speed 2 · 3 · 20 · 8 60 · 6
= 2,66 hours
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.
