STRENGTH REQUIREMENTS FOR SPECIAL CARS TO TRANSPORT 40-FT TRAILERS

The need for a lightweight flat car capable of carrying two refrigerated highway trailers 40 ft. in length is pointed up. The design parameters for such a car are discussed; basic dimensions of 85 ft. length, 8 ft. 6 in. width, and 62 ft. truck centers are established, and the expected static and dynamic forces including those engendered by the use of the trailer hitch on the car structure are analyzed. Three design solutions fulfilling the necessary basic dimensions and strength requirements are described along with subsequent changes which service experience and later testing indicated.
