Abstract
A trailer for transporting a freight container is comprised of a frame having a front frame section which is adapted to be coupled to a suitable road vehicle. A pair of displaceable horizontal side beams are secured to the front frame section and are provided with a hingeable rear gate formed by a pair of hinge arms. Each of the side beams has a suspension assembly to support a tandem wheel arrangement. Retractable vertical lifting piston cylinders are secured to a portion of the front frame and to the pair of hinge arms and are actuable to lift the pair of horizontal side beams and its wheels above a ground surface. Laterally extendable piston cylinders are also secured to the front frame and the hinge arms to displace the horizontal side beams outwardly and inwardly with respect to one another when lifted off the ground surface. Container lifting posts are secured to opposed ends of the front frame section and the hinge arms for removable connection to a container positioned between the side beams to lift and lower the container therebetween. Container connectors are secured to each of the side beams for securing a container thereto for transportation.
