B) ANTI-CRUSHING DEVICE SAFETY LIMIT SWITCH
This test is performed by lowering the platform from a >2 m floor height and by checking the following
conditions:
that descent stops automatically at a preset point
between the outer ends of the scissor here there is a space > 50 mm (check with a measuring
tape)
A buzzer warns when this operation is in progress.
A wait time of approximately 3 seconds has been included to allow the operator to check
for the absence of bystanders in the danger zone if the “platform descent” button remains
depressed once the anti-crushing position has been reached. The aforementioned audible
warning devices and indicator lights continue to operate during this period of time.
If the operations described above take place in the indicated sequence, it means that the limit switches
are functioning properly.
