TM 55-5811-188-14 Table 6-4.  Application of Materials for Blocking of Lightweight TEAMPACK System in General-Cargo Vessel (Fig 6-6) Item No.  Required Application A 2 Side blocks.  Each consists of 4- x 4- x 238-inch lumber.  Locate one piece against outside wheels on each side. B 2 End blocks.  Each consists of 4- x 4- x 64-inch lumber.  Locate on top of item A and against wheels as shown in figure 6-2.  Nail to item A with four 50d nails at each end of item B. C 4 Backup cleats.  Each consists of 4- x 4- x 12-inch lumber.  Locate on top of item A against the joint of each item B.  Toenail to each item A with four 20d nails. (2) Special    Design    Vessels.        All    seatrain trailer    vessels,    RORO    vessels,    landing    ships,    and attach-cargo vessels are equipped with patented lashing gear and pre-positioned fittings in the deck.  With proper application of patented lashing gear (as shown in figs 6- 7 and 6-8), blocking and bracing are not required.  The M1015  tracks  should  be  equipped  with  proper  rubber padding. (3) Loading Ships, Landing Craft, and Amphibious   Vehicles.      When   the   systems   are   to   be moved   extended   distances   or   through   rough   waters, tiedowns must be used.  Most vessels are equipped with turnbuckles with a sheep's foot on one end that fits into a  deck  cloverleaf.    A  suitable  substitute  may  be  used where turnbuckles are not provided. (4) Barge-Type (LASH and SEABEE) Ships. (a) TEAMPACK 1. The TEAMPACK system may arrive at  the  processing  area  with  hatches  padlocked  shut  to prevent  pilferage.    Since  this  vehicle  cannot  maneuver under   its   own   power,   its   tracks   are   not   braked   and transmission   is   set   in   the   neutral   position   to   permit towing in the loading area.  Contrary to normal stowage, idler wheel chocks should be in place when the system is positioned by crane in its final stow location.  Rubber pads  should  be  of  a  sufficient  depth  to  prevent  metal contact with the deck. 2. Floating  barges  noticeably  tilt  when heavy items are placed aboard them.  Tracked vehicles should  be  loaded  by  placing  one  at  one  end  and  the next at the other end.  This process should be repeated until  all  are  loaded.    Vehicles  may  have  to  be  loaded side  by  side  facing  opposite  directions  if  the  center  of balance   cannot   be   centered   in   the   barge   using   the stated procedures. 3. The   TEAMPACK   system   may   be adequately  blocked  and  braced  with  6x  8-inch  timbers. If the load orientation permits, blocking may be installed as a separator between the vehicle track and the barge bulkhead.  Blocking usually is installed in front of and in rear of the tracks, and the bracing part is force-fitted to the   bulkhead.      Loading,   blocking,   and   bracing   begin from the outer areas of the barge toward the center.  A single separator timber is installed against the tracks of the vehicle, and the next vehicle loaded is placed firmly against  the  timber.    The  vehicles  shall  be  secured  with wire rope and turnbuckles as shown in figure 6-9.  The void area remaining in the center of the barge after the final vehicle has been loaded shall be filled (fig 6-10) by cut and force-fitting blocking. (b) Lightweight  TEAMPAC.    When  the lightweight  TEAMPACK  systems  are  to  be  transported by  barge  for  a  long  distance  or  through  rough  waters, they will be blocked and tied down as shown in figure 6- 11. 6-9
