See appendix E for instructions. a. Place the carrier in the tiedown position on a semitrailer  by  using  a  crane  of  adequate  capacity (15-ton  minimum),  or  drive  the  carrier  onto  a semitrailer if a suitable ramp is available. b. Position  the  carrier  on  the  semitrailer,  using the  trailer’s  cargo  data  plate  as  guidance.  If  no cargo data plate is present, position the carrier so that  its  weight  is  evenly  distributed  over  the tractor and trailer axles. c. Set the parking brakes. Only  the  driver  of  the  carrier  is  allowed on  the  trailer  bed  during  loading  opera- tions. Do   not   load   on   side   or   lateral   slopes exceeding 10 percent or with a tractor-to- trailer offset angle greater than 50. Avoid loading on a severe downgrade, to prevent the  payload  from  rolling  forward  on  the trailer. The M901A1 and M981 launcher must be in the low stow position for transport. (See app  D  or  TM  9–2350–259  or  TM  9-2350- 266 series for low stow procedures.) 2 - 2
