wire rope loops
Each tiedown is made from one piece of 1/2-in. wire rope. Length as required. Form a complete lmp
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.
Space clamps 3 3/4 in. apart as shown. Use 1/2-in. cable clamps and alternately torque nuts to a min-

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.

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.
