This assembly includes the following components:
•
Winch Strap (1):
Connects the Strut Strap to the Winch.

Powers the Winch Assembly. This hydraulic motor and attached
Winch Spool holds the Winch Strap that pulls the aircraft wheel onto the Cradle and secures
it during towing. The Winch Spool also includes a Winch Spool Release Lever to manually
release the Winch, if needed. See
"EMERGENCY AIRCRAFT RELEASE” on page
.
•
Fender-Mounted Winch and Cradle Controls (2):
Allows the operator to control the Winch
Motor and Cradle without having to return to the Operator Compartment. If equipped, also
allows raising and lowering the Hydraulic Front Gate. See

Winch Strap Hook (3):
Secures the “D” Rings on the Strut Strap to the Winch Strap.

hydraulic power to the Winch OFF. Its primary use is in case the Winch Motor fails to shut off
while capturing an aircraft. See
"EMERGENCY AIRCRAFT RELEASE” on page
