(3) Cargo weighing up to the capacity of the cargo pallet which cannot be loaded in accordance with (1)
or (2) above can be loaded only after cribbing has been arranged to distribute the load as uniformly as possible
over the entire deck area. The balance must be maintained in the center of the pallet.
(4) Racks may be fabricated from standard 4 x 4 inch (10 x 10 cm) timbers with or without planks and
installed in the stake pockets to help retain loose cargo and bulk materials such as sand and gravel. If racks
are not used while carrying sand or gravel, the stake pockets should be plugged. Plug recessed tiedowns to
prevent loss of material. Clean recessed tiedowns and stake pockets after carrying dirt, sand or gravel.
2-4. Cargo Tiedown. The pallet has 24 tiedown hooks around the perimeter of the deck and 6 recessed
tiedown links in the deck for use in securing cargo. Stakes or racks may be fabricated and installed in the stake
pockets around the perimeter of the deck to help retain loose or bulk cargo. Nets or canvas may be used to
secure and protect cargo. Ropes should be run fore, aft, laterally and diagonally over the cargo to securely tie
and anchor the cargo to the tiedown hooks and recessed tiedown links. Do not secure tiedown ropes, net or
canvas to stakes or racks. The cargo must be secured so that no shifting will occur during retrieval, transport
and launching of the pallet. Shifting of cargo during transport may hamper launching of the pallet at its
destination. Due to the variety of cargo configurations which may be transported on the pallet, detailed
instructions on securing cargo are not given. Good judgment and experience must dictate when the cargo is
sufficiently secured
