Check the tripping force of the overspeed gov-
ernor F
GOV
:
This force must be at least twice as high as
the force measured on the safety gear syn-
chronization.
e.g.:
F1 = 300N =>
F
GOV
min = 2 x F1 = 2 x 300 = 600N
The maximum activating force F

max of
the overspeed governor rope is 2100N (see
chapter 3.4).
4.1
Static functions test
The function of the safety gear is to be checked
with empty car and at lower speed before the real
safety gear test is performed.
•
Activate the safety gear actuating lever (or
the overspeed governor rope as well by means
of the tripping function if available) manually.
At the same time, use the recalldrive to grad-
ually lower the car or counterweight.
•
Check if both safety gears worked at the same
time. If not, the safety gear synchronization
must be readjusted.
•
After a few centimeters, the car or counter-
weight should be caught by the pair of safety
gears.
•
To crosscheck the function of the safety gear,
the ropes have to slip in the traction sheave
when the motor is driven.
•
The safety gear contact must respond.
•
Release the safety gear by running up the car
or counterweight. Check that the actuating
mechanism and the safety gear contact have
returned to their initial positions.
The dynamic safety gear test can be done
when the function test is shown to be ok.
If there isn’t a correct gripping check the follow-
ing with the elevator data:
•
Mass to be gripped
•
Tripping speed
•
Guide rail dimensions and manufacture
•
Guide rail condition (dry or oiled)
•
Check the functionallity of the synchronisa-
tion
If the gripping after checking the above
mentioned points is not correct, the safety
gear must be replaced (please contact WIT-
TUR).
