Pallets and pallet nets are procured from the Air
Force. The 463-L pallet is the standard system for
the movement of concentrated cargo used by the Air
Force. Military airlift aircraft are equipped with a
dual-rail system consisting of rows of rollers, which
allow 463-L pallets to move easily into and out of
the aircraft. The 463-L pallet is made of
corrosion-resistant aluminum and has a soft wood
core. The pallet has an outside dimension of 108
inches by 88 inches and is 2 1/4 inches thick. The
cargo area space is 104 inches by 84 inches, which is
enough space to allow 2 inches around the 463-L
pallets to attach straps, nets, or other restraint
devices. A 463-L pallet weighs 290 pounds empty
and has a maximum load capacity of 10,000 pounds.
However, to prolong pallet life do not exceed a
pallet load of 7,500 pounds.
Pallet nets can provide adequate restraint for
10,000 pounds of cargo when properly attached to
the 463-L pallet. A net set contains two side nets
and one top net. The side nets are green, and the
top net is yellow. The side nets attach to the pallet
rings, and the top nets attach by hooks to the side
nets. These nets have multiple adjustment points and
may be tightened to fit snugly on most any load. A
complete set of 463-L nets (three nets) weighs 65
pounds. Other cargo restraints are chains and chain
tiedown devices. These are used for large items, such
as Conex boxes, Seabee shelters, and reefer units.
Five thousand-pound tiedown straps (fig. 4-14) are
used to secure equipment attachments and provide
individual item restraints. Additionally, the tiedown
straps provide supplemental restraint to the 463-L
Cargo is palletized from the heaviest to the
lightest. Large and heavy objects are distributed
evenly from the center of the pallet outward to
prevent the pallet from becoming heavy on one end.
This distribution also helps to maintain the C/B at or
near the center. Lighter or smaller items are
positioned on top or along the side of the heavier
cargo. Containers marked THIS SIDE UP are
placed upright, and cargo with special labels are
faced outward whenever possible. Pallets should be
constructed in a square or pyramid shape whenever
possible (fig. 4-15). This makes the load stable, easy
to handle, and easier to secure on the pallet.
Each 463-L pallet requires dunnage under the
pallet when not on board the aircraft. The dunnage
consists of three pieces of 4-inch by 4-inch by
90-inch timbers. The dunnage is placed in the center
and close to the outside edges of the pallet. This
prevents the pallets from warping and enhances
forklift operations. Each aircraft has restrictions as
to the dimensional size and shape particular to that
specific aircraft. Aisleways must be built on pallet
position three or four in a C-130 aircraft. Check the
particular requirements of the aircraft for which you
are preparing a load.
The marking of the C/B is not necessary on
individual 463-L pallets.
When 463-L pallet loads
are built correctly, the C/B will be at or near the
The pallets are weighed by using
The weight of the dunnage
must be weighed with the pallet. The scaled
weight of the pallet is recorded on the manifest
