CARGO HANDLING SYSTEM -GENERAL DESCRIPTION
General
The forward and aft cargo compartments each have cargo handling systems. Operation of the two systems is similar. Both systems use electrically and manually operated components. The bulk cargo compartment does not have a cargo handling system.
Controls
The controls for the forward and aft cargo handling systems are similar. The controls are near the forward part of the cargo door openings. You operate and set the forward or aft cargo handling systems using these interior and exterior controls:
*
Secondary joystick
*
Cargo control joystick
*
Cargo handling control panel.
The cargo system controller (CSC) uses inputs from the interior and exterior controls to position the electrically operated system components. The controller does not affect manually operated components.
The cargo handling accessory panels have system power relays and circuit breakers.
You can manually operate the components that are normally electrically operated if electrical power is not available.
Unit Load Devices
The cargo handling system lets the airplane carry different sizes of unit load devices (ULDs). The airplane can carry containers with profiles matching these sizes:
*
LD-1
*
LD-2
*
LD-3
*
LD-5
*
LD-6
*
LD-7
*
LD-10
*
LD-11.
Pallets matching these sizes can also be carried:
*
A
*
K
*
L
*
M
* N.

CARGO HANDLING SYSTEM -FWD CARGO ELECTRICAL/MECHANICAL COMPONENT LOCATIONS
General
The forward cargo handling system has electrical/mechanical components that let you load and unload ULDs.
These are the electrical/mechanical components:
*
Powered drive units (PDUs)
*
Lateral guides.
The usual operation of the electrical/mechanical components is automatically controlled by the cargo system controller. Some automatically controlled components you may operate manually. These are the components you may operate manually:
* Lateral guides.
Location
PDUs are in all areas of the cargo compartment.
Lateral PDUs are in the same area as the ball panels. There are two rows of lateral PDUs. Each row has three PDUs.
Longitudinal PDUs are on the left and right sides of the compartment in rows. There are fourteen rows of longitudinal PDUs. Each row has two PDUs.
Lateral guides are in the ball panel area of the cargo compartment.
Small lateral guides are between the forward and aft ball panels.
Large lateral guides are forward of the forward ball panels.

CARGO HANDLING SYSTEM -FWD CARGO MECHANICAL COMPONENT LOCATIONS
General
The forward cargo handling system has mechanical components that let you load, unload, and lock ULDs. These are the mechanical components:
*
End stops
*
Side guide rails
*
Stop/locks
*
Roller trays
*
Pallet locks
*
Ball panels
*
Center stop/locks
*
Guide rollers
*
Rollout stop/locks
*
Retractable guide roller/lock
*
Sill rollers
*
Center guides
*
Partial load stops.
Location
End stops are in the forward and aft ends of the cargo compartment. There are six in the aft end and four in the forward end. All end stops are the same except for the middle two in the aft end of the compartment. These do not give vertical restraint.
Side guide rails are along the sides of the cargo compartment. There are five on the left side and four on the right side of the compartment.
