11.5 Safety gear and overspeed governor
•
Required standard
Before activating the safety gear, verify that they are set up correctly on the guides and there is a gap of 2.0mm
between the safety gear and the back of the guides (
Figure 3 - Safety gear setup
).
At full speed, activation of the overspeed governor (
4.6 Overspeed governor tests, pg 5
) must cut power to the
motor and safety chain at G2. Full safety gear activation does not need to be complete in the annual check. This
can be complete in the 5 year check.
Once engaged, enter the lift and check behind the rear wall (
4.5 COP and rear wall removed, pg 5)
to see that the
safety gear on each side has began to engage. These should not be fully engaged at this stage as the motor will
have cut movement of the lift before full engagement.

Required action
If for any reason the safety gear has not engaged, investigate possible cause. This may be due to a linkage error at
any point between the overspeed activation to the safety gears themselves. If only one of the safety gears are
engaged, ensure that these are set up correctly (
Figure 3 - Safety gear setup
). Whilst the safety gear activation
plate ‘A’ is lined up in the middle of the access slot, the safety gear roller ‘B’ should be set up in the centre of each
of the safety gears.
