5.4.2.1 Measuring of the brake (lifting) force
with force gauge
Each test has to be documented
a) Detach the safety gear lever (1) from the rope
anchorage (2).
b) Fasten a clamp (3) with a force gauge (4) to the
governor rope.
c) Open the flyweight by hand (see mark A) or via
tripping device as long as they are going in
contact with the trip wheel shown at mark B.
d) Pull down the force gauge in the tripping
direction as long as the governor pulley or/and
the governor rope starts to move.
e) The shown value must be higher than the min.
brake force (ref. chapter 5.4.2)
f) Reset all to initial situation.
If the brake force is smaller the overspeed
governor must be re placed!
If, during this test, the governor rope moves
while the governor pulley stand still, the
sliding force of the rope inside the V-groove
is already smaller than the adjusted brake force.
This can be accepted when the force is higher than
the min. brake force expected.
Normally, with unworn V-groove, the sliding force
of the rope is higher than 1300N.
