TRANSPORT SEMITRAILERS: PART 2 OF 2 POC: Gerald O'Connor (810) 574-7932. (F) 5th wheel interchange coupling characteristics: Provide the following interchange coupling dimensions: (1) minimum clearance support radius measured from the centerline of the kingpin to any portion of the semitrailer 6 inches or more below the upper fifth wheel plate. (2) Minimum swing radius measured from the centerline of the kingpin to the most distant point on the semitrailer nose. (3) range of kingpin setting measured from the front of the semitrailer to the vertical centerline of the kingpin. (4) upper fifth wheel plate measured empty from the ground to the underside of the upper fifthwheel plate. (G) Tires: provide a general description of the type of tires including ply ratings and load ratings as well as total number used on the semitrailer to include the spare. (H) electrical/lighting system. Is the proposed semitrailer equipped with a 12/24 volt electrical system? If not, can the current 12 volt system be modified or would a new system be incorporated? Are the semitrailer running lights and side marker lights of the LED configuration? (I) corrosion control: The basic metal materials forming the semitrailer shall be treated and protected from failure due to corrosion in compliance with SAE J1617, J1804 and J1959. Describe the type of process and material used to protect the semitrailer in compliance with the noted references. (J) Transportability: Describe the type of tiedown provisions incorporated into the semitrailer which will allow for vehicle transport for highway, air, rail and marine modes of transportation. Describe the type of lift provisions provided on the semitrailer and can they withstand lifting the trailer with full payload? (K) Turning ability: with your trailer coupled to the noted prime movers, assess whether the combination can negotiate 90 degree angle turns in both directions without cramping, side slipping or inflicting damage to either the prime mover or semitrailer. (3) Production: (A) How long has the semitrailer been produced? (B) What is the total number of units produced? (C) Estimate your monthly economic quantity for the semitrailer. (D) Do you have the capacity or capability to manufacture 50-75 units a month? (E) Does your production involve any long lead time items? If yes, what are the items and their associated items? Forward all responses to this survey to: U.S. Army Tank-Automotive and Armaments Command (TACOM), ATTN: AMSTA-PM-T (Trailer Management Office/TMO), Gerald O'Connor, Warren, MI 48397-5000.
