TURNTABLE WINCH/CRADLE CONFIGURATION
The turntable Cradle and Winch Assembly includes a turntable with torque-sensing load cell,
which is part of a single- or multi-level Aircraft Protection System. See
This area includes the following components:
•
Cradle (1):
Carries the aircraft nose gear during towing operations. The front portion of the
Cradle lowers to capture the aircraft, and raises to provide ground clearance during towing
operations. The Cradle includes a Wear Plate on the underside that protects the Cradle and
aircraft from excessive wear. This will be either:
> UHMW high-density plastic Wear Plate that protects hangar floors.
> AR steel Wear Plate is standard for operations that do not require protecting hangar
floors and that have high wear exposure, such as airline ramp operations.
•
Hydraulic Front Gate (
optional
;
not shown
):
If equipped, can be raised or lowered using
the fender-mounted and/or Instrument Panel controls. See
• Turntable (2):
Includes a torque-sensing load cell that measures torque forces being
applied to the aircraft nose landing gear.
•
Rear Gate (3):
Limits how far the aircraft wheel can advance on the Cradle.
•
Winch Limit Switch (4):
Stops the Winch Motor when contacted by the aircraft wheel.
•
Cradle Lift Cylinders (5):
Lift and lower the Cradle.
•
Fender-Mounted Winch/Cradle Controls (6):
Allow the operator to control the Cradle and
Winch functions, and to raise/lower the Hydraulic Front Gate (if equipped). See
