TM   55-3930-660-14 b. Loading. Position the VRRTFL as indicated in the   stow   plan,   so   sufficient   tiedown   points   are available.  Set  the  parking  brake.  Place  the  trans- mission  in  neutral.  Rest  the  forks  on  shoring,  or leave  them  raised  about  10  inches  off  the  deck. Disconnect  the  battery  (if  required  by  the  ship’s master)  once  the  VRRTFL  is  positioned  aboard  ship. c.  Tiedoum  and  Blocking.  Figure  4-1  and  table 4-2 provide instructions for restraining the forklift against forces encountered in severe marine condi- tions (para 4-1). Table  4-2.  Tiedown  Procedures  for  Securing  6K  VRRTFL  in  a Cargo Ship Hold (Fig 4-1) Item Procedure Wire rope Each tiedown is made from one piece of 1/2-in. loops (4 wire rope. Length as required. Form a com- required) plete loop between forklift-truck and ship tie- down provisions. The angle between the cables and deck (as viewed from the side) should be as close to 45° as possible. The wire rope ends must overlap at least 24 inches. Tension the wire rope by using two cable grippers and a chain hoist (3-ton) or “come-along.” Cable clamps Space clamps 3-3/4 inches apart as shown. Use 1/2-in. cable clamps and alternately torque nuts to 65 ft.-lb. Thimbles Use thimbles to protect cable at sharp bends. Attach to cable with 5/8-in. cable clamp. Thimbles are optional for the VRRTFL fittings. Blocking Position and nail blocking. *NOTE* 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 strength,  torque  1/2-in.  cable  clamp  nuts to 65 ft-lb. To ensure proper torque, alter- nately torque both nuts. Cable-loop  working  strength  (two  loaded cables) is 80 percent of the cable breaking strength.  Example:  23,000  x  2  x  0.8  = 36,800 lb for 1/2-in. cable. 4-4.   Lifting   Operations Shiploading  will  often  require  lifting  of  the VRRTFL  into  position  aboard  ship.  Shipside  and shoreside  cranes  are  usually  rated  in  long  tons (LTON),  2,240  pounds,  and/or  metric  tons,  1000 kilograms.   To   lift   the   VRRTFL,   a   crane   and sling-set capacity of at least 12 LTON or 13 metric tons is needed. See figure 4–2. **WARNING** Crane   lifting   operations   are   inherently dangerous.  Avoid  being  under  overhead loads. 4 -2
