CARGO HANDLING SYSTEM -RETRACTABLE GUIDE ROLLER/LOCK -OPERATION
Operation
The retractable guide roller/lock has these positions:
*
Container load -The roller is up and the restraint is down to move containers into the cargo compartment
*
Pallet load and Contain/Pallet Unload -The roller and the restraint are down. Use this position to load pallets or unload containers and pallets.
*
Lock -The roller is down and the restraint is up when cargo movement into or out of the cargo compartment is complete.
You use the pedal to manually lower the restraint. You use the fork to manually lower the roller. Push the pedal all the way down to move the restraint down. Push down on the inboard end of the fork to move the roller down.

CARGO HANDLING SYSTEM -LATERAL GUIDE -INTRODUCTION
General
Lateral guides make sure containers stay straight on the forward ball panels for the load or unload operation. Some guides also give vertical restraint and more anchor fittings for pallets.
Seven lateral guides are in the forward cargo compartment. Eight lateral guides are in the aft cargo compartment. There are three different types of lateral guides:
*
Large with forward and aft vertical restraints (forward cargo compartment)
*
Small with heavy weight rail and base (forward cargo compartment)
*
Small with light weight rail and base (aft cargo compartment).
Large Guides
The large lateral guides in the forward cargo compartment give vertical restraint for pallets forward and aft of the guide.
Small Guides
The small lateral guides in the forward cargo compartment are heavier in construction than the ones in the aft compartment. This makes them more resistant to the higher longitudinal loads in the forward compartment.
