safety gear synchronisation.
•
Check the mobility of the gripping roller and
the safety gear in the outer housing.
•
Check even running of left and right safety
gear (Synchronisation).
•
Check the rope connection for movability /

5.1.3
Cleaning of guide rails
Any dust or dirt on the guide rails can have influ-
ence to the friction between the guide rail and
the safety gear. This means that the guide rails
must be cleaned carefully whenever the dirt be-
comes visible on the guide rails or in minimum
once per year.
As cleaning fluid a disc brake cleaner or a
similar fluid should be used.
Mechanical cleaning like filing, grinding is
not permitted.
Only the marks from the safety gear rollers
caused during safety gear activation may be re-
moved with a file or a scraper.
5.2
Periodical tests
The standard levels of returning tests should not
be higher than the standards of the tests before
installation.
These returning tests are not allowed to cause
wear or stresses that impair the operation relia-
bility of the elevator. The tests must be done with
empty car and reduced speed.
The reset of the safety gear must be done
by an expert person.
Each gripping test has to be documented and a
copy of the test report should remain in the ele-
vator book.
For detailed adjustment dimensions and testing
procedures refer to chapter 4. “Function testing”.
