  • Load transfer apparatus for use between a tractor hitched to a trailer
    Patent number: 4087111
    Abstract: A transfer apparatus for use between a tractor-like vehicle and a trailer-like vehicle connected by a hitch connection means. The transfer apparatus comprises a linkage member attached between the tractor and trailer with at least a portion of the linkage member extending between the tractor and trailer at a position vertical with respect to the hitch connection means. Means in conjunction with the linkage member such as a hydraulic actuator may supply a rigid connection through the linkage member thereby preventing free hinging in a vertical plane between the tractor and trailer at the hitch connection means. The rigid connection may, for example, prevent rear-up of the tractor and shift weight to the rear driving wheels of the tractor.
