ABSTRACT:
A dump trailer for transporting containers includes a movable frame that receives an associated container. A support plate operatively engages a fifth wheel of a tractor. Interposed between the support plate and the frame is a telescopic hoist assembly to pivot the frame relative to the support plate. A draft arm also extends between the support plate and frame to guide movement of the frame during the hoisting operation. Loading and unloading of the container relative to the tilted frame is controlled by a cylinder and cable assembly secured to the frame. The support plate and frame also include a series of flanges for locking the frame against lateral and longitudinal movement relative to the support plate.
