Rigging Palletized Load System (PLS) on a 24-Foot, Type V Platform for Low-Velocity Airdrop
SECTION II-RIGGING A-22 CARGO BAGS
DESCRIPTION OF LOAD
7-17. The palletized load system can be moved from the drop zone and transported on a specially designed
truck. Bulk supplies are lashed to the pallet, giving the load integrity for transport. The pallet has swivel
rings along the sides for lashing the load. The pallet is lashed to the airdrop platform for low-velocity
airdrop. The load shown consists of eight A-22 cargo bags. Adapt these procedures to rig other items of
bulk supplies. Ammunition listed in FM 4-20.153/MCPR 4-11.3B/TO 13C7-18-41, as certified for low-
velocity airdrop, may be rigged using these procedures. The rigged load may not be more than 100 inches
high. Refer to FM 4-20.102/MCRP 4-11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 for the weight
limitations for the number of parachutes to be used.
PREPARING PLATFORM
7-18. Prepare a 24-foot, type V platform as shown in Figure 7-22.

3. Install a suspension link in holes 6, 7, and 8 on each side of the platform.
4. Install a tandem link on the front of each platform side rail using holes 1, 2, and 3.
5. Install a suspension link in holes 29, 30, and 31 on each side rail.
6. Install a suspension link in holes 41, 42, and 43 on each side of the platform.
7. Install clevises on bushings 3 and 4 of each front tandem link.
8. Install clevises on bushings 1 and 3 of each first suspension link.
9. Install clevises on bushings 1 and 2 of each second suspension link.
10. Starting at the front of the right and left platform side rail, install clevises on the bushings
bolted to holes 4, 14, 17, 23, 35, 37, 38, 45, 46, and 48.
11. Install a double clevis on bushings 4 and 37 on each side of the platform.
12. Starting at the front of the platform, number the clevises 1 through 16 on the right side,

Note. Rig the A-22 containers according to FM 4-20.153/MCRP 4-11.3B/TO 13C7-18-41.
2 Place four A-22 containers on the honeycomb, 8 inches from the front edge of the pallet.
Allow space for the endboards to rest on the honeycomb.
3 Place four A-22 containers on the second section of honeycomb, at least 8 inches from the
containers placed in step 2 above. Allow space for the endboards to rest on the
honeycomb.

2. All dimensions are in inches.
3. For loads different from that shown in this section, make the endboards the same height as the
load configuration.
4. The instructions given are for one endboard. Four are required for this load.
Step:
1. Cut four 90- by 36-inch pieces of 3/4-inch plywood.
2. Make 2- by 3-inch cutouts as shown. Tape the sharp edges of the cutouts.
3. Place an endboard against the front and rear of each of the two groups of containers. (Not
shown)

11.3J/NAVSEA SS400-AB-MMO-010/TO 13C7-1-5 and as shown in Figure 7-34. Safety the suspension
slings as shown in Figure 7-35.
Notes.
1. This drawing is not to scale.
2. Instructions are for one side. Repeat for the other side of the load.
Step:
1. Place the end loop of a 12-foot (4-loop), type XXVI sling in the bell of a large clevis. Bolt
the clevis to the right front suspension link. Connect the free end of the 12-foot sling to a
3-foot (4-loop), type XXVI sling with a two-point link.
2. Attach a 3-foot (4-loop), type XXVI sling to each center suspension link with a large clevis.
Place both 3-foot slings in the bell of a large clevis. Pass a 16-foot (2-loop), type XXVI
sling through one spool of a two-point link. Place both ends of a 16-foot sling on the bolt
of the large clevis.
3. Pass a 9-foot (2-loop), type XXVI sling through a spool of a three-point link. Place both
ends of the sling on the remaining spool of the two-point link used in step 2 above.
4. Bolt the 3-foot sling used in step 1 above to the three-point link so that the third spool
points upward. Bolt a 3-foot (4-loop), type XXVI sling to the upper spool of the three-point
link.
5. Place the end loop of a 20-foot (4-loop), type XXVI sling in the bell of a large clevis. Bolt
the clevis to the rear suspension link.
6. Repeat steps 1 through 5 for the left side.

DESCRIPTION OF LOAD
8-1. Forty-eight 155-millimeter projectiles, twenty-four (M231) powder canisters and six fuse cans are
rigged for low-velocity airdrop on an 8-foot, type V airdrop platform. The load uses two G-11B cargo
parachutes.
Notes.
1. The load shown is using metal crates. However, wooden crates may be used with three
lashings and a load binder.
2. If the metal locking rods are missing, three lashings, D-rings and load binders will be needed.
