SECTION II - RIGGING FOUR 500-GALLON DRUMS
DESCRIPTION OF LOAD
3-24. The four collapsible drums are rigged on a 28-foot platform with five 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 25,700
pounds with a width of 108 inches and a length of 372 inches. It has an over-
hang of 18 inches in the front and 9 inches in the rear. The load has a center of
balance of 172 inches from the front of the platform.
Notes: 1. For drums filled with liquid other than water, use Table 1-1 to
recompute the weight.
2. If the load varies from the one shown, the weght, height, CB, tipoff
curve, and parachute requirements must be recomputed.
3. Do not pressurze drums with air.
PREPARING PLATFORM
3-25. Prepare a 28-foot type V airdrop platform using two tandem links, eight
suspension brackets, and 68 tie-down clevises as shown in Figure 3-23.
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.

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 22, 23, and 24 on each platform side rail.
5. Install a suspension bracket to bushings 33, 34, and 35 on each platform side rail.
6. Install a suspension bracket to bushings 49, 50, and 51 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 tie-down clevis to bushings 2, 3, and 4 of each second suspension bracket.
10. Install a tie-down clevis to bushings 1, 2, and 3 of each third suspension bracket.
11. Install a tie-down clevis to bushing 3 of the fourth suspension bracket.
12. Starting at the front of each platform side rail, install a tie-down clevis to the
bushings bolted to holes 10, 11, 13, 14, 18, 26, 31, 42, 43, 46 (doubled), 47, 52
(tripled), 53, 54, and 56 (doubled).
13. Starting at the front of the platform, number the clevises bolted to the right side
from 1 through 28 and those bolted to the left side from 1A through 28A.
14. Number the clevis on bushing 46 as clevis 20, and 20A and the doubled clevis as
19 and 19A.
15. Number the clevis on bushing 56 as clevis 28, and 28A and the doubled clevis as
27 and 27A.

SECTION III- RIGGING FIVE 500-GALLON DRUMS
DESCRIPTION OF LOAD
3-47. The five collapsible fuel drums are rigged on a 32-foot, type V platform
with six G-11 cargo parachutes. Each drum is filled with 432 gallons of liquid.
When empty, each drum weighs 250 pounds and is 62 inches long and 53 inches
in diameter. The five drums also have a 350-GPM pump with a separator and
hose box as an accompanying load. The total rigged load has a maximum weight
of 30,355 pounds with a width of 108 inches and length of 411 inches. It has an
overhang 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
3-48. Prepare a 32-foot type V airdrop platform using two tandem links, eight
suspension brackets and 72 tie-down clevises as shown in Figure 3-43.
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.
