  • Patent number: 4595210
    Abstract: The invention is a trailer suitable for hauling fruit bins or the like, pivotally connected to a hitch and supported by an axle assembly which includes an offset cross shaft. An hydraulically actuated cam assembly rotates the cross shaft so that the rear end of the trailer can be lowered to the ground for easy loading and unloading without raising the forward end. The trailer also has a stop mechanism on its rear end which is actuated by the same cam assembly which rotates the axle, so as to automatically place it in operative position when the trailer is raised.
