A long time ago, I experimented w/ this style of bridge... I used tiles to
start and manually retracted it w/ my finger...I later added a winch, but
this led to some stress issues and imbalanced/jerky motion...
Before trying to use old technic gears and 1x4 plates on the right side of
the bridge, I tried a simple lever and tile system...essentially I put a 2x8
or 2x 10 (I forget) plate underneath a 6x16 black plate...I then "made a
tract" by mounting 1x2 tiles 1-2 studs apart on top of pair of 1x8
plates...these were attached to my structure on either side of the 2x8/2x10
plate underneath the 6x16 plate...I affixed a "handle" made out of bricks
and plates that slid in a slit I designed to the right of the bridge...I hid
this inside a room next to the gate...the advantage to this was that the
drawbridge did not "dip" in meeting the other side of the moat or just fall
out of the mechanism due to its own weight or overextension...
I eventually scrapped the idea when my bridge span became too long and I had
run out of the proper Technic pieces to do a geared bridge....before I moved
on though...I tried using the town small wheels underneath part of the span
to aid motion...this was many years ago when lego came out w/ the nonstudded
wheel hubs that allowed bricks to be placed on either side of the wheels to
hide their presence.
I hope this explanation is more helpful than confusing
