ABSTRACT:
A slip-proof connection provided between the tractor and trailer of a tractor-trailer combination for carrying the superstructure of a mobile crane. The connection or mechanism comprises a mounting assembly secured to the tractor bed, a mounting plate carried on the front portion of the trailer supporting the crane superstructure, and means for cooperatively interconnecting the two mechanisms to assure an interlocked connection therebetween. The connecting mechanism comprises a positive interlock wherein a mounting post carried on the mounting plate on the tractor is received into a complementary opening provided in the mounting plate on the front end of the trailer, and a sleeve is then mounted on the mounting post and positively locked in position to hold the tractor and trailer locked together. Although the combination does not provide for the quick disconnect of the tractor from the trailer as is common with typical fifth wheel designs, it does permit articulation of the tractor and trailer combination. Further, means are provided in association with the connecting mechanism to permit oscillation of the tractor and trailer in multiple oscillatory modes. Additionally, locking means are provided on the mounting assembly to retain multiple oscillatory modes for rough terrain movement and to lock out one of the oscillatory modes for highway travel.
