3.3 COUPLING THE DRIVING BAR
It is the responsibility of the person who installs the safety gear to properly position the driving bar in relation
to the safety gear, as well as to properly synchronise the safety gears controlled by that driving bar. The driving
bar is properly positioned when the trolley’s pivot is in the protection plate’s central position.
Once
it has been fitted and the safety gear’s roller’s trolleys have been attached to the driving bar’s tripping
bars, it should be checked that both trolleys operate simultaneously, controlled by the driving bar. This should
be checked in both directions, ascending and descending.
The overspeed governor should generate a minimum force that it should be twice the force to ensure the
synchronized performance of the safety gears.
⚠
The Standard demands that the installation incorporate an AC-15 or DC-13 safety contact as defined in
EN 60947-5-1.
