Abstract:
An antijackknife system for a trailer having a trailer hitch with a ball joint and alignment arms, a housing on the underside of the trailer at a front end of the trailer, and a front end of the housing having a ball joint socket. A slide plate is in an interior of the housing and an actuator is on the underside of the trailer. The actuator is operatively coupled to a rear end of the slide plate. Casters are attached to an axle assembly at a rear end of the trailer. The casters each have a locking plate attached thereto with the locking plate having a locking slot. Locking pins are positioned on the axle assembly. The slide plate is placed in a first position by the actuator wherein the ball joint socket rotates freely on the ball joint and the locking pins are placed in the locking slots. Alternatively, the slide plate is placed in a second position by the actuator wherein the ball joint socket does not rotate on the ball joint and the locking pins are pulled out of the locking slots.
