    • A trailer construction comprising a rear floor overlying and attached to the rear wheel bogie and a front floor, at least a portion of which is disposed for over-the-road hauling at a level vertically below the level of the rear floor to provide cargo space below the rear floor and forward of the bogie. The two floors are mounted on the trailer such that when the trailer is to be loaded or unloaded, the front floor portion may be elevated relative to the rear floor to cause the two floors to be brought into alignment and thereby provide a continuous interior floor surface over which fork lift trucks or other cargo handling equipment can be operated to load and unload cargo.

    • In a first form of the invention, a mobile unit includes means for accurately locating a road-worthy chassis thereon. Lifting and lowering means is carried by the mobile unit for lifting and lowering a moveable platform mounted on said chassis. A chassis is moved onto the mobile unit, the platform is raised so that the upper surface is substantially flush with the upper surface of a cargo deck in the aircraft, cargo is transferred between the upper surfaces, the platform is then lowered onto the chassis, and the chassis is moved off the mobile unit. In another form of the invention, a mobile dock includes a load carrying portion supported by a plurality of wheel assemblies. Means is provided for raising and lowering the load carrying portion with respect to the wheel assemblies and comprises struts including cam operated steering means whereby the wheels are steered upon relative vertical movement of the load carrying portion with respect to the wheels. In this latter form of the invention, a road-worthy chassis is moved onto the load carrying portion of the mobile dock and the dock is them moved into operative position. The load carrying portion of the dock is raised until the upper load carrying surface of the road-worthy chassis thereon is substantially flush with the upper surface of the cargo deck, whereupon cargo is transferred between said upper surfaces. The dock is then moved away from the aircraft and the load carrying portion is lowered whereupon the road-worthy chassis is moved off of the mobile dock. Two forms of the invention may also be used in combination with one another wherein the upper surface of the platform supported above a chassis on the mobile unit may serve as a bridge for cargo passing thereover onto the upper load carrying surface of a chassis carried by a dock disposed adjacent the mobile unit.
