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.

1. A trailer for transporting a freight container, said trailer comprising a frame having a front frame section adapted to be coupled to a road vehicle, said frame further having a pair of displaceable horizontal side beams, a hingeable rear gate formed by a pair of hinge arms, each said hinge arm being hingedly secured to a rear end of a respective one of said horizontal side beams at a rear end of said side beams, each of said horizontal side beams having a wheel supporting suspension secured thereto, and one or more wheels secured to said suspension, retractable vertical lifting means secured to a portion of said front frame and said pair of hinge arms and being actuable to lift said pair of horizontal side beams and said one or more wheels above a ground surface, laterally extendable means secured to said front frame section and said hinge arms to displace said horizontal side beams outwardly and inwardly with respect to one another when lifted off the ground surface by said retractable vertical lifting means, container lifting and lowering means secured to said front frame section and said hinge arms for removable connection to a container positioned between said side beams to lift and lower the container therebetween, and container connecting means secured to each said side beams for securing the container thereto for transportation. 2. A trailer as claimed in claim 1, wherein said retractable lifting means are vertically supported telescopic legs secured on opposed sides of said front frame, and to each of said hinge arms, and a hydraulic piston secured to each said telescopic legs to cause extension and retraction thereof. 3. A trailer as claimed in claim 1, wherein each side beam of said pair of horizontal side beams is provided at a front and rear end thereof with a transverse extendable connecting linkage, said extendable connecting linkage at said front end being displaceably secured to said front frame section and at said rear end being displaceably secured to a respective one of said pair of hinge arms, each said extendable connecting linkage having a hydraulic piston constituting said laterally extendable means. 4. A trailer as claimed in claim 3, wherein each said transverse extendable linkage is a sliding coupling assembly. 5. A trailer as claimed in claim 4, wherein each said sliding coupling assembly at said rear end of said side beams is constituted by a slide plate secured to a hinge flange attached to a hinge connection at said rear end of said side beams, said slide plate being displaceably retained captive between guide members secured to said hinge arm for sliding displacement along a straight longitudinal axis of said hinge arm. 6. A trailer as claimed in claim 5, wherein said guide members are spaced apart guide wheels in frictional rotational engagement with opposed parallel edge portions of said slide plate. 7. A trailer as claimed in claim 1, wherein said container connecting means is a container corner locking device secured adjacent opposed ends of a top surface of each said side beams for locking engagement with lower corner engaging formations of ISO certified containers. 8. A trailer as claimed in claim 1, wherein each of said side beams are provided with container alignment pads on an inner side surface thereof. 9. A trailer as claimed in claim 1, wherein said container lifting and lowering means are constituted by four vertical posts, each said post being secured in a respective one of four corner areas of said frame, a lifting piston mounted in said posts, said lifting piston having a piston rod end secured to a coupling connector for displacement of said coupling connector along a vertical slot opening of said post, said coupling connector being adapted for removable attachment to a container. 10. A trailer as claimed in claim 1, wherein there is further provided a container arresting bumper secured to an inner face of said front frame. 11. A trailer as claimed in claim 1, wherein said suspension means comprises a pivotal wheel support arm secured at a forward pivot end to a pivot pin retained in a frame attachment member for pivotal connection of said pivotal wheel support arm to said frame, a wheel axle assembly secured at a rear free end of said pivotal wheel arm and adapted to connect a wheel thereto, a shock absorber connecting bracket secured to said forward pivot end of said pivotal wheel support arm and having a shock absorber connecting member extending above said pivot pin, said shock absorber connecting member being pivotally displaceable in facial alignment with a stationary shock absorber connector secured to said frame, a shock absorber retained captive between said shock absorber connecting member and said stationary shock absorber connector and compressible therebetween by said shock absorber connecting member being displaced toward said stationary shock absorber connector by upward movement of said pivotal wheel support arm to absorb vertical displacement loads transmitted to said pivotal wheel support arm by the wheel connected thereto. 12. A trailer as claimed in claim 11 wherein there is further provided lateral displacement stabilizing and external shock absorbing means secured to said pivotal wheel support arm to arrest said pivotal wheel support arm against lateral loads. 13. A trailer as claimed in claim 12 wherein said stabilizing and lateral shock absorbing means is constituted by a vertical extension plate secured to said pivotal wheel support arm and having a vertical flat friction surface displaceable against a flat vertical arresting surface of said frame, and a bushing of shock absorbing material immovably retained in said frame attachment member about said pivot pin. 14. A trailer as claimed in claim 13 wherein said vertical flat friction surface is constituted by an ultra-high molecular weight polyurethane plate secured to said surface of said vertical extension plate, said vertical extension plate being a steel plate. 15. A trailer as claimed in claim 11 wherein said shock absorber connecting member is a flat seating plate secured to a support frame of said shock absorber connecting bracket, and a connecting fastener securing an end of said shock absorber thereto, said shock absorber being a pad of compressible material. 16. A trailer as claimed in claim 15 wherein said stationary shock absorber connector is a flat transverse wall surface formed integral with said frame. 17. A trailer as claimed in claim 11 wherein each of said horizontal side beams are straight hollow side beams, each said side beam having one or more rectangular wells formed therein from an outboard vertical side wall of said side beam, said well having a transverse flat wall section defining said stationary shock absorber connector, and a connecting fastener securing an end of said shock absorber thereto, said frame attachment member being an attachment bracket secured to a flat bottom wall of said side beam behind and adjacent said transverse vertical side wall, said pivotal wheel support arm supporting the wheel connected thereto inside said rectangular well. 18. A trailer as claimed in claim 1, wherein said front frame section has a towing frame structure for removable attachment to a hitch of the road vehicle. 19. A trailer as claimed in claim 1, wherein there is further provided a manual locking device adjacent opposed ends of said side beams to lock said side beams with respect to said front frame section when said side beams are displaced to an outward position and to lock said hinge arms to said side beams when said hinge arms are at an open position, and gate locking means at a free end of said hinge arms to lock said hinge arms together when said hinge arms are at a closed position.
