CARGO HANDLING SYSTEM -LATERAL GUIDE -PHYSICAL DESCRIPTION
Physical Description
Lateral guides are spring loaded electrical/mechanical units. The guides have these parts:
*
Crank (2 for small guides, 3 for large guides)
*
Guide rail
*
Base
*
Electrical actuator
*
Attenuator assembly
*
Downlock pawl
*
Electrical connector
*
Uplock pawl
*
Anchor fitting (2) (large lateral guides only)
*
Vertical restraint (2) (large lateral guides only)
*
Uplock pawl release lever (large lateral guides only).
Functional Description
The electrical actuator controls the position of the guide rail. The pawls and pawl release lever manually operate the guide rail.
Training Information Point
You remove the lateral guides as a single unit.

CARGO HANDLING SYSTEM -LATERAL GUIDE -OPERATION -LOCK DOWN
General
Normally the guide rail on the lateral guides moves electrically to down when you move cargo forward or aft. If the rail does not move electrically you can manually move and lock it down with these components:
*
Uplock pawl (small guides only)
*
Uplock pawl release lever (large guides only)
*
Guide rail
*
Down lock pawl.
Lock down
For small guides move the uplock pawl away from the crank. For large guides use the uplock pawl release lever to move the uplock pawl away from the crank. The uplock pawl is spring loaded. Hold the pawl or lever to keep the pawl away from the crank.
While you hold the pawl or the release lever push the guide rail down. The guide rail is spring loaded up.
As you hold the guide rail, move the downlock pawl to lock the guide rail down.
Release
Push and hold down the guide rail. This removes pressure on the downlock pawl.
Move the downlock pawl to unlock the guide rail.
Release the guide rail. Springs automatically move it up.
Training Information Point
If you manually lower a lateral guide, you must manually release it before it will operate electrically.

CARGO HANDLING SYSTEM -LATERAL GUIDE -OPERATION -LIFT UP
General
To lift up a lateral guide when it does not move up electrically, you must manually operate the toggle link in the attenuator assembly.
Lift up
Use a common screwdriver or similar long, thin object to trip the toggle link on the attenuator assembly. Springs lift the guide rail automatically if the toggle link is tripped correctly.
The attenuator resets automatically when the guide rail is lowered manually.
Access
Access to the toggle link is different for large and small guides.
Large guides -you access the toggle link thought a side access hole in the base of the lateral guide. This hole is on the forward side of the guide.
Small guides -you access the toggle link from the top of the lateral guide. The tool you use to the trip the toggle link fits between the rail and the base of the guide.
Training Information Point
If you manually lift a lateral guide, you do not have to move it down before electrical operation. The lateral guide will reset itself when power is put on the system.
