Abstract:

A trailer for livestock and other loads comprising a frame resting on an axle member on which the vehicle wheels are mounted. The axle member is provided with two arms, one pivoted on each side of the trailer on supports extending above the frame. The wheels are swingable forwardly about the pivots to a position over center with respect to the pivots and by blocking the wheels and forcing the trailer rearwardly it is raised by the pivoting arms and tilts downwardly toward the rear until the arms strike stops limiting the swinging movement of the arms. A drawbar is pivoted to the frame on a horizontal axis parallel to that of the wheels and is positioned so that rearward force when the wheels are blocked tends to tilt the trailer. The trailer is arranged for easy handling by one man without the use of hydraulic jacks or the like.
