CARGO HANDLING SYSTEM -AFT CARGO MECHANICAL COMPONENT LOCATIONS
Sill rollers are in the door sill area. The aft cargo handling system uses cantilevered rollers for all of its sill rollers. The forward system uses both cantilevered and non-cantilevered.
Center guides are along the center of the cargo compartment.
Partial load stops are all along the cargo compartment. Sixteen stops attach to the roller trays in four rows. There are four stops in each row.

CARGO HANDLING SYSTEM -ELECTRICAL GENERAL DESCRIPTION
General
The cargo handling system gets power for control from the P320 ground service/handling power panel. The system gets operating power from the P300 auxiliary power panel.
PSEU number one supplies cargo door position information. The cargo system controller (CSC) lets the system operate only if the cargo door is full open.
CSC Inputs
The cargo system controller (CSC) gets inputs from these components:
*
Cargo handling accessory panel (system power relays and circuit breakers)(P35 fwd, P39 aft)
*
Secondary joystick
*
Cargo control joystick
*
Cargo handling control panel (Switches, P24, P27)
*
Hard wired program pins give controller installation location and information about system options. (Fwd cargo compartment, LD-4/LD-8 option, aft large cargo door option, crew rest in place 1 option, crew rest in place 2 option, no gearmotor devices installed).
The CSC does not get inputs from the PDUs or the lateral guides. The CSC has no interface with the AIMS.
Operation
The CSC controls the position of these electrical/mechanical components:
*
Powered drive units
*
Lateral guides.
To supply power to the system these conditions must be true:
*
the ground handling bus has power
*
the cargo door is full open
*
the SYSTEM POWER switch on the cargo handling control panel is in the ON position.
You can tell that power is on when the system power LED comes on.
Use the switches on the cargo handling control panel to configure the system. The switches let you set the system for the type of cargo you need to load or unload (CONTAINERS OR PALLETS). The switches also let you enable sets of power drive units (PDU FWD or AFT and PDU LEFT, CENTER OR RIGHT).
You use the cargo control joystick to move ULDs in all directions, FORWARD, AFT, IN or OUT. The secondary joystick lets you move ULDs in two directions, FORWARD or AFT. The secondary joystick does not let you move ULDs onto or off of the ball panels. The cargo system controller uses your inputs for system configuration and joystick position to operate the components.

CARGO HANDLING SYSTEM -MECHANICAL GENERAL DESCRIPTION
General
These are the mechanical components that you manually operate:
*
Pallet locks (fwd compartment only)
*
Stop/locks (fwd compartment only)
*
Center stop/locks
*
Center guides
*
Rollout stop/locks
*
Retractable guide roller/lock
*
Partial load stops.
Operation
A typical unloading/loading operation usually requires the use of both electrically and manually operated components. The type of ULDs (containers or pallets) and the amount of cargo (partial or full load) tell you which components to use.
Pallet locks and stop/locks let you lock pallets in place. The lock position gives vertical and longitudinal restraint for the pallets.
Center guides in the area of the ball panels can be locked down. You do this so pallets can be loaded and unload.
You use the center stop/locks for these functions:
*
To give lateral separation between containers
*
To give lateral restraint for containers
*
To give vertical restraint for containers.
You use the rollout stop/locks for these functions:
*
To give lateral restraint for containers and pallets
*
To give vertical restraint for containers and pallets.
You use the retractable guide roller/lock for these functions:
