4 Very heavyHoist units which are usually subject to maximum or 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 ac-cording to the definitions below:

1 LightHoist 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 =

60 · hoist speed

Operating time/day =

2 · 3 · 20 · 8= 2,66 hours

60 · 6

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

Key data for hoist drives EKDR-Bas 3 - 5 - 10Design is in accordance with the VDE regulations and the FEM design rules to meet the high demands made on elec-tric hoists.

1) Fuse links also apply in conjunction with a cross-travel motor.2) The lengths of the supply lines are calculated on the basis of an earth-loop impedance of 200 mΩ.
