WARNING
To avoid death, serious injury, or damage to equipment, do not attempt to retrieve,
launch or transport a loaded pallet without first securely tying down the cargo.
CAUTION
An unbalanced payload or overloaded pallet may hamper retrieval and launching
operations.
a. General. Cargo weight cannot exceed 10,000 pounds (4536 kg) when the pallet is to be retrieved
and/or launched by the transporter, retrieved and/or launched by sling, dumped or transported cross-country.
Cargo up to 18,500 pounds (8391 kg) may be loaded for highway transportation when the pallet is secured on
the transporter and is not to be launched. Use a forklift truck to position loads and slide into final position as
required. For smooth launch and retrieval, it is important to distribute loads as widely and equally as possible.
Keep loads centered to maintain pallet balance. If it is necessary to drive the lift truck onto the pallet, 8 x 8
inch (20 x 20 cm) timbers approximately 14 feet (4.27 m) long must first be positioned full length under the
pallet, parallel to the sides and a ramp positioned at the rear of the pallet as shown in figure 2-2.
Figure 2-2. Timber and Ramp Placement for Use With Forklift
b. Procedures. To avoid damage to the pallet, the following procedures must be adhered to.
(1) General purpose pallets, 40 x 48 inches (102 x 122 cm), loaded with equal weight, which do not
exceed the values shown in table 2-1, should be arranged on the cargo pallet in a manner which distributes the
total weight over the deck as uniformly as possible, maintaining the balance in the center.
(2) General purpose pellets, 40 x 48 inches (102 x 122 cm), loaded with cargo of unequal height or
weight exceeding the values of table 2-1 must be loaded in accordance with figure 2-3.
