Introduction
DESCRIPTION OF LOAD
The IC45 crawler carrier is a small commercial off the shelf tracked dump truck. The IC45
crawler carrier is 98 ½ inches high (reducible to 77 ½ inches with the removal of the roll over
protection system (ROPS) and canopy cover), 175 inches long, 101 ½ inches wide (reducible to
88 ½ inches with removal of the side mirrors) and weighs 12,790 pounds.
The IC45-2 IHI crawler carrier is a small commercial off the shelf tracked dump truck with an
attachment assembly. The IC45-2 IHI crawler carrier is 97 ½ inches in height (reducible to 81 ½
inches with the removal of the roll over protection system and canopy cover), 103 inches in
width, 200 inches long, and weighs 16,500 pounds.
The M973A, 1 ½-ton cargo carrier small unit support vehicle (SUSV) is a tracked vehicle with a
driver’s compartment and a cargo-troop carrier compartment attached to the rear. The vehicle is
271 inches long, 74 inches wide, 90 ½ inches high, and weighs 10,000 pounds. The vehicle must
be rigged with an accompanying load that weighs at least 2,000 pounds but not more than 2,100
pounds. The accompanying load shown in this manual is 105-millimeter ammunition rigged on
the front end of the platform; however other equipment may be used.
SPECIAL CONSIDERATIONS
CAUTION
Only ammunition listed in FM 4-20.153/MCRP 4-11.3B/TO 13C7-18-41
may be airdropped.
The loads covered in this manual include hazardous material as defined in AFMAN 24-204(I)/
TM 38-250/NAVSUP PUB 505.MCOP4030. The hazardous materials must be packaged, marked
and labeled as required by AFMAN 24-204(I)/TM 38-250/NAVSUP PUB 505/MCO P4030.19H.
A copy of this manual must be available to the Joint Airdrop Inspectors during the before and
after loading inspection in accordance with AR 59-4/OPNAVINST 4630.24C/AFI 13-210(I)/

4. Face the flat part of the link to the front of the rail.
5. Install a suspension bracket in holes 25, 26, and 27 on each platform side rail.
6. Face the flat part of the link to the rear of the rail.
7. Install a clevis on bushings 1, 2 and 3 on each tandem link.
8. Install a clevis on bushing 4 on each rear suspension bracket.
9. Starting at the front of each platform side rail, install clevises on each platform side rail using
bushings bolted on holes 10, 11,13, 15, 17, 20, 22, 23, 29, 30, 31, and 32.
10. Starting at the front of each platform side rail, number the clevises bolted to the right side from 1
through 16 and those bolted to the left side from 1A through 16A.

Steps:
1. Use a 48- by 60- by ¾-inch sheet of plywood as a base.
2. Cut two 2- by 6- by 60-inch pieces of lumber. Nail each piece of lumber flush with the front, rear
and sides using 8d nails.
3. Cut two 2- by 6- by 37-inch pieces of lumber. Nail the lumber flush with one piece on each side
between the front and rear pieces using 8d nails.
4. Drill six 2-inch holes centered in the 2- by 6-inch lumber as shown above.

3 Position the stack, centered from side to side and flush with the rear edge of the platform.
4 Position the parachute stowage platform on top of the honeycomb stack and the bed of the
dump truck. The parachute platform will overhang the rear edge of the airdrop platform 6
inches.

8 Form a 30-foot lashing and route one end up through the middle left side hole in the parachute
stowage platform. Run the lashing across the parachute platform and down through the middle
right side hole and through clevis 14. Route the other free end through clevis 14A and back up
through the middle left side hole, across the platform, and down through the middle right side
hole. Secure the lashing with two D-rings and a load binder on the right side.
