The electrical working principle is as follows:
Press the start button (SB), and the contactor (KM) will be
powered; motor (M) is energized to drive the gear pump
supplying oil to push the carriage upward; release the start
button, and the contactor (KM) is open, then the motor (M)
will lose the power, so the carriage will stop rising. As for
the clear-floor lift, if the vehicle is lifted up to the top and
contacts the limit switch on the top beam, the contactor
(KM)) will open, then the motor (M) will lose the power, so
that the carriage stops lifting. Emergency stop button to
emergency power-off function.
