Rigging the Mass Supply Load on Dual Row Airdrop
System Platform
DESCRIPTION OF LOAD
11-1. The mass supply (fast box) load (Figure 11-1) is rigged on an 18-foot dual row platform. The rigged
weight is 14,120 pounds. The load is rigged with two pre-constructed plywood boxes. The forward box
(box 1) has a minimum weight of 3,500 pounds and a maximum weight of 6,000 pounds. The aft box (box
2) has a minimum weight of 2,800 pounds and a maximum weight of 5,000 pounds. The load is 97 inches
high, 94 inches wide, 216 inches long, and the center of balance is 90 inches from the front edge of the
platform. The load is rigged with two to four G-11D cargo parachutes. The M-1 release is used with this
load. The minimum allowable weight is 8,100 and the maximum allowable weight is 14,500.
PREPARING PLATFORM
11-2. Inspect, or assemble and inspect, a dual row airdrop platform with outrigger assemblies and
outrigger platform support weldments according to TM 10-1670-268-20&P/TO 13C7-52-22 and as shown
in Figure 11-2.

right side and 1A through 29A on the left side.
3. Label the tie-down rings according to Figure 2-2.
4. Construct four 30-foot lashings. Route the free ends of the one 30-foot lashing through
platform tie-down rings A2 and B2.
5. Route the free ends of one 30-foot lashing through tie down rings A4 and B4.
6. Route the free ends of one 30-foot lashing through tie down rings A6 and B6.
