ABSTRACT:
Anti-jackknifing apparatus for combination with conventional tractor-drawn trailers wherein the tractor includes a forward operator's cab and a rearward fifth wheel assembly having a skid-plate. The skid-plate conventionally includes a pair of longitudinally rearwardly extending guide-lugs having outward-sides and also inward-sides horizontally angularly converging toward an upright kingpin or other pivotal association with the trailer. The anti-jackknifing apparatus comprises a generally horizontal longitudinally extending ram terminating as a forward head-end, which ram and head-end has an inactive normal-station and also an anti-jackknifing extended-station respectively located rearwardly remote from and toward the skid-plate. A header is rigidly attached to the ram head-end and carries a pair of forwardly extending arms and preferably also a medial tongue which at ram forward extended-station abut an outward-side and an inward-side, respectively, of the guide-lugs to avert a potential jackknifing panic situation.
