A trailer is described, defining a floor extending from a first end, and comprising at least one first displaceable platform onto which goods can be loaded from the first end of the trailer. The first platform is supported such that it can be elevated when loaded and advanced away from the first end of the trailer when loaded. The first platform is preferably rolled forwards onto support tracks provided on the sidewalls of the trailer. The trailer may also include a load-carrying well with its own moveable cargo platform or platforms, and the first platform is loaded and moved up and over the well, thereby increasing the capacity of the trailer. Corresponding cargo-carrying vehicles, and loading methods are described and claimed.

A trailer in accordance with claim 1, wherein the lifting mechanism is arranged to maintain the vertically displaceable platform substantially parallel to the trailer floor. 8. A trailer in accordance with claim 1, wherein vertical movement of the further displaceable platform is effected by hydraulic rams. 9. A trailer in accordance with claim 1, wherein vertical movement of the vertically displaceable platform is effected by screw jacks. 10. A trailer according to claim 1, wherein the trailer further comprises at least one second displaceable platform which can be displaced from a first upper position to a second lower position within the well, wherein the first platform is arranged to be elevated and advanced forwards such that at least a part of the first platform is directly above the well. 11. A trailer in accordance with claim 1, comprising means for elevating and advancing the first displaceable platform, when loaded, to at least one elevated forward position in the trailer, the trailer further comprising supports mounted on sidewalls of the trailer, said supports being arranged to support the first displaceable platform in the elevated forward position. 12. A trailer in accordance with claim 11, wherein the first displaceable platform is substantially parallel to the trailer floor when in said elevated forward position. 13. A trailer in accordance with claim 12, wherein said supports comprise at least one pair of tracks mounted on opposite sidewalls of the trailer. 14. A trailer in accordance with claim 13, wherein said tracks are arranged substantially parallel to the trailer floor. 15. A trailer in accordance with claim 13, wherein the first displaceable platform comprises a plurality of rollers, and said tracks provide rolling surfaces for said rollers such that the first displaceable platform may be elevated and then driven forwards such that it rolls onto the supports, to the elevated forward position. 16. A trailer in accordance with claim 15, wherein each track defines a channel for receiving said rollers. 17. A trailer in accordance with claim 13, wherein the tracks further comprise end stops arranged to limit forward movement of the first displaceable platform. 18. A trailer in accordance with claim 13, further comprising controllable stops operable to lock the first displaceable platform in the forward elevated position. 19. A trailer according to claim 1, wherein the first displaceable platform can be advanced forwards only from a predetermined vertical position. 20. A trailer according to claim 19, wherein the predetermined vertical position is defined by tracks provided in walls of the trailer, said tracks being fixedly located in the predetermined vertical position, and the first displaceable platform can be advanced forward along said tracks. 21. A trailer in accordance with claim 1, wherein the first displaceable platform is a load-carrying platform, the trailer comprising a first section defining a load-carrying front floor, a rear section defining a rear floor, a well section located between the front and rear sections, and means for lowering payload into the well section, wherein a further vertically spaced is vertically displaceable above the rear floor between raised and lowered positions, and the vertically displaceable platform carries the load-carrying platform which is horizontally displaceable over the well when the vertically displaceable platform is in the raised position, the load-carrying platform being displaceable from the vertically displaceable platform onto supports mounted on sidewalls of the vehicle. 22. A trailer in accordance with claim 21, wherein rollers are interposed between the vertically displaceable platform and load-carrying platform. 23. A vehicle according to claim 22, wherein the load-carrying platform supports rollers along its longitudinal edges which run on tracks extending along longitudinal edges of the vertically displaceable platform. 24. A trailer in accordance with claim 21, wherein rollers are interposed between the sidewall supports and the load-carrying platform. 25. A trailer according to claim 24, wherein the sidewall supports include rollers on which formations on the longitudinal edges of the load-carrying platform roll. 26. A trailer according to claim 25, wherein the sidewall support rollers are mounted on plates defining inner sidewalls of the well section. 27.
