Rigging 500-Gallon Drums with the 350-GPM
Wheel-Mounted POL Pumping Assembly, Filter/Separator
Assembly, and Hose Box
SECTION I - RIGGING THREE 500-GALLON DRUMS
DESCRIPTION OF LOAD
3-1. The three collapsible drums are rigged on a 24-foot platform with four G-11
cargo parachutes. Each drum is filled with a maximum of 432 gallons of liquid.
When empty, each drum weighs 250 pounds and is 62 inches long and 53 inches
in diameter. The 350-GPM pump with filter/separator and hose box are accom-
panying loads. The total rigged load has a maximum rigged weight of 21,000
pounds with a width of 108 inches and a length of 324 inches. It has an over-
hang of 18 inches in the front and 18 inches in the rear.
Notes:
1. For drums filled with a liquid other than water, use Table 1-1 to
recompute the weight.
2. If the load varies from the one shown, the weight, height, CB, tipoff
curve, and parachute requirements must be recomputed.
3. Do not pressurize drums with air.
PREPARING PLATFORM
3-2. Prepare a 24-foot type V airdrop platform using two tandem links, eight sus-
pension brackets, and 48 tie-down clevises as shown in Figure 3-1.
Notes: 1. The nose bumper may or may not be installed.
2. Measurements given in this section are from the front edge of the
platform, NOT from the front edge of the nose bumper.

Steps:
1. Inspect, or assemble and inspect, the platform as outlined in TM 10-1670-268-
20&P/TO 13C7-52-22.
2. Install a tandem link on the front of each platform side rail using holes 1, 2, and
3.
3. Install a suspension bracket to bushings 6, 7, and 8 on each platform side rail.
4. Install a suspension bracket to bushings 18, 19, and 20 on each platform side
rail.
5. Install a suspension bracket to bushings 29, 30, and 31 on each platform side
rail.
6. Install a suspension bracket to bushings 41, 42, and 43 on each platform side
rail.
7. Install a tie-down clevis to bushing 4 of each tandem link.
8. Install a tie-down clevis to bushings 1 and 4 of each first suspension bracket.
9. Install a double clevis to bushing 4 of the fourth suspension bracket.
10. Starting at the front of each platform side rail, install a tie-down clevis to the
bushings bolted to holes 9, 10, 15 (triple), 16, 23, 24, 25, 26, 33, 34, 38, 39, 40,
44 (triple), 45, 46, and 48 (double).
11. Starting at the front of the platform, number the clevises bolted to the right side
from 1 through 24 and those bolted to the left side from 1A through 24A.
12. Number the clevis on bushing 48 as clevis 24 and 24A and the doubled clevis as
23 and 23A.
