Abstract
A trailer assembly suitable for carrying a container of proppant has a frame with a first side rail and a second side rail extending in generally parallel relation to each other and a plurality of wheels rotatably mounted below the frame. The frame has a plurality of cross members extending between the side rails. First and second outriggers extend across the side rails so as to each have one end extending outwardly of one of the side rails and an opposite end extending outwardly of the other side rail. The first and second outriggers are suitable for receiving the container of proppant thereon. The frame has a first section positioned above the wheels and a second section positioned at a level lower than a level of the first section. The proppant container is placed on the first section.
