New Caution Label
To point you in the right direction, your CK will get a new caution label. The
logistics assistance representative (LAR) who works with the container kitchen has
the label. He’ll attach it inside the winch cover. Among other things, the label
reminds you to crank the winch counterclockwise to lower the wings and clockwise
to raise them.

•
Cranking the winch
counterclockwise but for-
getting to unhook the
safety strap.
The wing
lowers until the safety strap
stops it. Same old story: If
you continue to crank,
loose cable winds off the
winch drum, gets tangled
and binds. Again, you need
to untangle the cable and
crank clockwise to wind it
back onto the drum. Then
raise the wing until you can
unhook the safety strap.
•
Continuing to crank the
winch after the jacks are
connected.
You’re just ask-
ing for more tangled cable.
Don’t forget to unhook safety strap
Stop
cranking when wing is
level and jacks are connected
Operators tended to crank counterclockwise (the
wrong direction). Here again, loose cable winds off the
winch drum, gets tangled and binds. And once again,
you need to untangle the cable and crank clockwise to
wind it back onto the drum and raise the wing.
If you continue to crank counterclockwise and bind
the cable, you’ll lose tension on the winch. That causes
the winch socket to come loose, and a loose socket’s a
clear sign you’ve got cable binding.
One other detail worth knowing: During operations,
the cable often slips a little as it moves back and forth
around the winch drum, causing the wing to move
unevenly. This is normal. Don’t worry about it.
Just one
problem has
surfaced when
operators try
to raise the
wing, also
known as
wing
closure.
Learn the
right way
to raise and
lower the
kitchen's
wings…
…and
you'll
never
be
late for
a meal
again!
So
stop
cranking
once the wing is level
and the jacks are
connected.
CAUTION
To avoid binding and damage to the winch or the cable:
•Make sure the cam locks are in
the open position before cranking
wing down.
•After cam locks are fully free do
not forget to detach safety straps.
•Crank handle in correct direction,
clockwise to raise the wing an
counterclockwise to lower the wing.
