Remove base- plate and bridge assembly from the outside stow- age positions, and restrain them inside the carrier. c. M113A3 and M730A2 Carriers. Put the trans- mission in the SL position. d. M1068 Carrier. Requires only two shackle assemblies. The rear tiedown provisions do not need shackles. 3-4. Loading Procedures a. Materials. The shipper must supply materials for shipping and tiedown on the railcar when chain-tiedown cars are unavailable. Table 3–2 lists the necessary materials. It gives four different options for tiedown materials. The rear ramp of the M577-series carriers requires special preparation to prevent it from falling during transport. See appen- dix E for instructions. The M730A2 guided missile equipment carrier has three tiedowns on the rear. Therefore, it needs two more cables and/or chains than specified in table 3-2. For use in rail transport, load binders must be marked with the safe working load. Table 3-2.
