6.2. Explanation to drive groups FEM 9.511 for rope drives
The electric wire rope winches are classified according to different drive groups, DIN 15020, FEM 9.511,
ISO4301/1 (see tech. data, page 24 )
Those drive groups refer to the rope drive and all mechanical parts of the winch.
It determines the period of time of safe operation depending on load collective.

Apart from drive groups, the rope has to be checked and serviced regularly according to
DIN15020, if necessary, replace.
By comparing those data with the actual operating conditions and times the consumed part of
the calculated operating time can be determined
The consumed part of the calculated operation has to be recorded by the operator (e.g. writing,
counting, measuring)
After expire of the calculated working life the winch has to be given a thorough examination
