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

The size of the hoist is determined by the load

spectrum, average operating time per working day, load capacity and reeving.

4 Very heavy

Hoist units which are usually subject to maximum or almost maximum loads.

3 Heavy

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

2 Medium

Hoist units which are usually subject to small loads but rather often to maximum loads.The load spectrum

(in most cases estimated) can be evaluated ac-cording to the definitions below:

1 Light

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

great accuracy?6. Is horizontal load travel necessary?7.

How is the hoist to be controlled?

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.

Operating time/day = 2 · average hook path · no. of cycles/hour · working time/day
