The size of the hoist is determined by the load spectrum, average operating time per working day, SWL and reeving.

4 Very heavyHoist units which are usually subject to maximum and almost maximum loads.

3 HeavyHoist units which are usually subject to medium loads but frequently to maximum loads.

2 MediumHoist units which are usually subject to small loads but rather often to maximum loads.

The load spectrum(in most cases estimated) can be evaluated in accordance with the following definitions:

1 LightHoist units which are usually subject to very small loads and in exceptional cases only to maximum loads.

Selection criteria

1. What are the operating conditions?2. What is the specified safe working load?3. To what height must the load be lifted?4. What is the required lifting speed?

5. Do the loads need to be lifted and lowered with high precision?

6. Is horizontal load travel necessary?7. How is the hoist to be controlled?

Example SWL 20 tLoad spectrum “medium” from tableHoist speed 6 m/minCreep hoist speed 1 m/minReeving 4/1Average hook path 5 mNo. of cycles/hour 20Working time/day 2 - 4 hoursThe average operating time per working day is estimated or calculated as follows:

For the “medium” load spectrum and an average daily operating time of 2,25 hours, the upper table shows group 2 m. For a load capacity of 20 t and 4/1 rope reeving, the table below indicates hoist size DR 20 – 20.
