Systems Descriptions
Bridging Microswitch: The
bridging microswitch is located
at the bottom of the left (rear)
vertical arm. See Photos A
and B. An adjustment screw is
built into the platform stop
block.
The bridging microswitch will
be deactivated if the outboard
end of the platform contacts
the unloading surface before
the inboard end while the
DOWN switch is pressed.
The deactivated bridging
microswitch interrupts power to
the DOWN switch circuit and
stops the down travel of the
platform (while allowing the roll
stop to deploy).
