Place the carrier in the position For the M113A and M730A2, put the transmission indicated by the stow plan so sufficient tiedown in SL position. points are available. Set the parking brakes and c. Tiedowns. Table 4-2 provides instructions for place the transmission in neutral. Disconnect the restraining the carriers against forces encountered battery once the carrier is positioned aboard ship. in normal marine operations. Table 4–2. Tiedown Procedures for Securing a Carrier in the Hold of a General Cargo Ship Item Procedure Chain tiedowns Install at indicated locations. The number of chains used will depend on chain sizdstrength. Use eight chains, NSN 4010-00-803-8858, two for each load binder. Cross two cables on the front and rear of the carrier. wire rope loops Each tiedown is made from one piece of 1/2-in. wire rope. Length as required. Form a complete lmp (4 required) between carrier and ship tiedown provisions, The angle between the cables and deck (as viewed horn the side) should be as close to 45° as possible. Cross cables on the fkont and rear of the car- rier. The wire rope ends must overlap at least 24 inches. Tension the wire rope by using two cable grippers and a 3-ton chain hoist or come-along. Cable clamps Space clamps 3 3/4 in. apart as shown. Use 1/2-in. cable clamps and alternately torque nuts to a min- imum of 65 ft-lb. Thimbles Use thimbles to protect cable at sharp bends. Attach to cable with %-in. cable clamp and torque cable clamps to a minimum of 95 ft-lb. The methods described in this chapter for lifting and securing vehicles are recom- mended procedures. Other methods of handling and stowage may be used, pro- vided they ensure safe delivery without damage. To develop full cable loop working 4-5. Lifting Operations Shiploading will often require lifting the carriers into position aboard ship. Shipside and shoreside cranes are usually rated in long tons (LTON), 2,240 pounds, and/or metric tons (t), 1000 kilo- grams. To lift a carrier, a crane and sling-set capacity of at least 13 t (12.8 LTON or 28,660 pounds) is needed. strength, 1/2-in. cable clamp nuts must be Crane lifting operations torqued to at least 65 ft-lb. To ensure dangerous. Do not stand proper torque, apply torque in stages to both nuts alternately. loads. 4-2 are inherently under overhead
