Brake-wear monitoring
For wear monitoring of the brake, regularly check the release path and if necessary adjust it.
If the release path cannot be adjust any more replace the brake disk.
Works on the brake may only be executed by authorised and competent personnel.

The electric wire rope winches are classified according to different drive groups, DIN 15020, FEM 9.511, ISO4301/1 (see tech.
data, page 17)
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 acc.g 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 (i.e. writing,
counting, measuring)
After expire of the calculated working life the winch has to be given a thorough examination 1)
1) only by manufacturer or competent personnel authorised by manufacturer
