Alfa company is responsible for following these
procedures that include the following: the removal of
dump truck headache racks, equipment exhaust
stacks, dozer blades, counterweights, and equipment
roll over protective structure (ROPS). Also, the fuel
tank of a vehicle to be embarked by airlift must be
between one-fourth and three-fourths full; however,
when the vehicle has to be placed on the ramp inside
the aircraft, the fuel tank should never be more than
one-third full. Accomplishment of these procedures is
a major area of responsibility for the air det
equipment platoon; therefore, make sure you know
where Alfa company placed the bolts, nuts, and parts
for the disassembled equipment because the air det
will be required to reassemble these items on site.
After the CESE is cleaned, inspected, and
serviced by Alfa company, the dispatcher notifies the
MOCC that the CESE is ready to be transferred to
the Weighing and Marking station.
WEIGHING AND MARKING
To plan an airlift and to break down loads for
individual aircraft correctly, you must determine the
weights and center of balance (C/B) of the two main
divisions: vehicles and general cargo.
The weight and center of balance of vehicles
are determined with secondary loads (mobile loads)
mounted. Mobile loads are items of baggage or cargo
transported in truck beds and trailers that must be
included in the total weight of a vehicle. To determine
the center of balance (C/B) on a vehicle, the 20th
Naval Construction Regiment Embarkation Staff
(R23), Gulfport, Mississippi, recommends the
following procedures:
Step 1. Establish the reference datum line
(RDL). The RDL is the farthest forward point of a
vehicle.
Step 2. Measure distance 1 (D1). D1 is the
measurement in inches from the RDL to the center
line of the front axle.
Step 3. Measure distance 2 (D2). D2 is the
measurement in inches from the RDL to the center
line of the intermediate axle or rear axle.
NOTE: The distance 2 measurement location
for vehicles with tandem axles is measured from the
RDL to the trunnion.
Step 4. Measure distance 3 (D3). D3 is the
measurement in inches from the RDL to the center
line of the rear axle. This step is performed on
vehicles that have three or more axles and on
towed vehicles that will remain married (attached)
to a vehicle when loaded on the aircraft. The axles
on a towed vehicle will become D4, D5, and so
forth (fig. 2-5).
To perform Steps 5, 6, and 7, drive the vehicle
onto portable scales (fig,. 2-6) placed under the tires
on each axle.
