Abstract
A slidable fifth-wheel assembly permitting the relative positions of a tractor and its associated trailer to be adjusted includes switching means which activates an alarm in the cab of the tractor when the fifth-wheel reaches a desired position. This desired position is a trade-off between rear axle weight and drive axle weight. The switching mechanism includes a switch mounted on the base plate of the fifth-wheel assembly. The actuator arm of the switch is extended by means of a coil spring which is engaged and displaced by the coupling shoe of the fifth-wheel assembly.
