FIFTH WHEEL KINGPIN PERFORMANCE—COMMERCIAL TRAILERS AND SEMITRAILERS

Foreword— This This Document has also changed to comply with the new SAE Technical Standards Board Format. 1.

Scope—The   purpose of this recommended practice is i s to establish test procedures and minimum performance standards for kingpins and their their supporting structure manufactured manufactured to SAE specificat specifications. ions. The dimensions shown in SAE J700 will permit the establishment of standard clearances in the installed condition which, in turn, will permit fifth wheel manufacturers to design their products to establish interchangeability with any kingpin made and installed to the SAE specification.

De Defi fini niti tion ons—  s— GVW = Gross Vehicle (Trailer) (Trailer) Weight, including payload and veh vehicle icle (trailer) weight. TVW = Total Weight of Towed Vehicles (Trailers). The kingpin, when completely installed, shall fit within the tolerances and dimensions shown in SAE J700. The kingpin, when installed, shall meet the following performance requirements: a. Withs Withstand tand a force force "A" o off 1.1 1.15 5 TVW in a ffore ore or aft d direct irection. ion. (See Figure Figure 1.) b. Withs Withstand tand a cycling cycling force force "B" of 0 0.4 .4 TVW in a fore fore and a aft ft dire direction ction for for 500 000 000 cycles cycles.. (See Fig Figure ure 1.) c.
