Figures 4-5 through 4-7 show the proper method to sling load the HMMWVs. This method is also used when the HMMWV must be lifted for other modes of transportation. The data plate, located on the left rear fender of each HMMWV, also shows the sling-load diagram. b. All models of the HMMWV at GVW can be transported by CH-47 and CH-53 aircraft. However, the ve- hicle maximum weight and climatic conditions may restrict external transport by UH-60 aircraft. The M997 am- bulance and the M1037/M1042 shelter carriers may be externally transported by the UH-60 helicopter provided the maximum vehicle weight is within the performance criteria of the aircraft. c. The slinging procedures for the HMMWV M998 cargo truck, the M966, TOW weapons carrier, and the M1087 shelter carrier will be completed by using the following materials, personnel, and procedures: (1) Materials. (a) Sling set (10,000-lb capacity), NSN 1670-01-027-2902. (b) Tape, adhesive, pressure-sensitive, 2-inch-wide roll. (c) Cord, nylon, Type III, 500-pound breaking strength. (2) Personnel. Two men can prepare and rig the load in 15 minutes. (3) Preparation. (a) Fold the mirrors forward in front of the windshield; then tie the mirrors together with Type III nylon cord. Also, using Type III nylon cord, tie the mirrors to the lift provisions that protrude through the hood. (b) Secure all equipment inside the vehicle with tape, nylon cord, and/or lashings. . (c) For the M1037, ensure that the shelter is secured to the truck with wire rope or tiedown assem- blies. Secure all equipment inside the shelter with tape, nylon cord, and/or lashings, and close and lock the door. (d) Make sure that the fuel content of the vehicle does not exceed 75-percent capacity. Check the fuel tank cap, oil filter cap, and battery caps for proper installation. (e) Set the vehicle parking brakes and put transmission in neutral. 4-5
