T M     5 5 - 2 4 2 0 - 2 2 4 - 14 CHAPTER  7 RAIL  TRANSPORTABILITY  GUIDANCE Section   I. 7-1.   Scope This  chapter  provides  rail  transportability  guid- ance for movement of the SEE, HME, and HMMH. It covers technical and physical characteristics and safety  considerations.  It  also  prescribes  the  mate- rial  and  guidance 7-3.    General required  to  prepare,  load,  and Section   II.   TRANSPORT The   transportability   guidance   contained   in   this section  applies  when  the  SEE  or  variants  are transported  on  CONUS  railways.  Consideration  is given  to  single  and  multiple  movements  on  the types of flatcar normally used to move this vehicle. The   SEE   or   variants   can   be   transported   on   a 50-inch-high  deck  railcar  without  restriction throughout CONUS. 7-4.    Preparation. a. The  SEE  will  be  in  the  travel  configuration for  rail  transport.   A   1/2-inch   wire   rope   (safety cable)  with  two  clamps  will  be  installed  taut  (not tight)  around  the  ROPS  and  the  backhoe  attach- ment for a safety device if the locking device fails. Outriggers  are  tied,  with  1/2-inch  wire  rope  and two  clamps,  in  their  retracted  position  to  prevent extension  during  transport.  Foam  padding  will  be tied around the hydraulic cylinders on the backhoe attachment  for  protection  against  damage  during rail shipment. b. The  HME  will  be  in  the  travel  configuration for  rail  transport.   A  1/2-inch  wire  rope  (safety cable)  with  two  clamps  will  be  installed  taut  (not tight) around the ROPS and entrenched implement for a safety device if the locking device fails. c. The HMMH will also be in the travel configu- ration  for  rail  transport.  Secure  rear  crane  imple- ment  with  a  1/2-inch  wire  rope  (safety  cable) looped  around  crane  arm  and  through  right  side center  tiedown  provision  on  chassis  for  a  safety device   if   the   locking   device   fails.   Repeat   same procedure on left side. Also the outriggers are tied, GENERAL tie down the SEE, HME, and HMMH on open-top flatcars. 7-2.   Maximum   Use   of   Railcars Additional   cargo,    as  approved  by  the  activity — offering the SEE or variants transported with the SEE or ON   CONUS   RAILWAYS with  1/2-inch  wire  rope  and for transport, may be variants. two  clamps,  in  their retracted  position  to  prevent  extension  during transport.  Tie  felt  padding  around  the  hydraulic cylinders on the backhoe implement for protection against damage during rail shipment. 7-5.   Loading   the   SEE   or   Variants   on   a General-Purpose    Flatcar a. The  SEE  or  variants  may  be  placed  in  the tiedown  position  on  a  railcar  by  a  crane  (refer  to para  6–4b  for  lifting  instructions),  or  it  may  be driven  or  towed  onto  the  railcar  provided  a  suit- able ramp or bridge is available. CAUTION Do not allow the SEE or variant to exceed 3  miles  per  hour  (walking  speed)  during loading or unloading operations. b.  Loads  shown  in  figures  7–1  and  7–2  are based  on  a  flatcar  that  is  9  feet  4  inches  wide. Table  7-1  is  a  bill  of  materials  and  table  7-2  is the  application  of  materials  for  securing  the  SEE or variants on general-purpose flatcars. 7-6.   Loading   the   SEE   or   Variants   on Special-Purpose    Flatcars The  loads  shown  in  figures  7-4  and  7-5  are  based on  the  use  of  CONUS  conventional  wood-deck chain-tiedown  flatcars.  These  cars  are  equipped with special heavy-duty tiedown anchors and chain assemblies contained in a channel along each side of the car and on each side of the center sill. Table 7–3   presents   application   of   chain   tiedowns   for securing the HMMH. 7-1
