Specifications

Release the push-button immediately if the safety device
does not function and stop the hoist – at least 3 meters
(10 feet) above the ground level. The brake(s) are applied
when the push-button is released.
If so, start the test from item 4 again.
7. Run the car upwards minimum 0.2 m (8 in.) with the drop
test push-button box to release the mechanism of the safety
device.
Then take the car down to the normal lower landing by
inching little by little with the drop test device.
Be careful so that the safety device is not activated again.
8. Remove the test cable and then try to start the car in the
upward direction.
The microswitch in the safety device shall, when the safety
device has been actuated, prevent the hoist from starting
when the test cable has been removed. In other words, it
must not be possible to start the hoist.
9. Reset the safety device according to instructions later in this
chapter.
10. Reset the ”Normal/Inspection” switch in the electric cabinet
to the ”Normal” position.
If you don’t succeed with the drop test, contact nearest
ALIMAK representative.
Calculating the safety device stopping distance
The safety device stopping distance can be measured between
the end face of the safety device and the end of the indicating
pin – measure ”L”, see figure.
Multiply measure ”L” with factor acc. to the table for the safety
device in question.
IMPORTANT! The safety device must be exchanged if
measure ”L” exceeds the value stated on the safety’s sign.

Note: the indicating pin (6) is made of a

caliper for measuring.
