C. SECURING PAYLOAD VEHICLES
1. Make sure wood bumpers are on the M747 gooseneck for all single vehicle loads.
Use wood dunnage on M870 and M172A1 goosenecks when a portion of the
payload vehicle will contact the gooseneck (fig79). Avoid metal-to-metal contact.
2. Make sure curbing is properly located against payload tracks on M747 and
M1000 semitrailers. After payload is on the M747, move curbs from position F to
position A (or store them if not needed in position A).
3. Tighten chains using the loadbinders.
4. Secure excess chain to the tension-bearing part of the chain.
5. On chain devices, secure open-faced hooks to the chain link with wire.
6. Lock chain tightening devices with wire. Tighten jamnuts on turnbuckles with a
wrench.
7. Set brakes on payload vehicles and put their transmissions in neutral.
8. Make sure gun turrets or other rotating parts are properly secured.
9. Make sure the retractable clearance lights are in the retracted position for regular
loads or are extended for all loads wider than the semitrailer bed.
10. Make sure ramps are raised and properly secured.
11. Make sure all basic issue items are properly stowed on the semitrailer.
12. Check the tractor and the semitrailer brakes and all lights to make sure they are
operating.
