A self tracking land vehicle includes a number of cargo or passenger cars and a drive car. Each cargo car may have a chassis with a standardized container mounted on it. At least front and rear axles which have at least two inflatable tires each are provided for each of the cars. The front axle is pivotable about a vertical axis with respect to the car, and the rear axle is fixed. A substantially transversely rigid connection connects the front of each car to the rear of the preceding car, to form a land train. Each car and associated transversely rigid connection is substantially the same length, and all of the axles of all of the cars are spaced from each other substantially the same effective longitudinal distance, so that the train is self tracking. At least some of the axles of some of the cars may be driven by an electric motor, and a lead drive car is provided having a front with at least one steerable axle, a power plant in the front car producing electricity to drive all of the electric motors.

Load-lifting apparatus includes a pair of elements moveable on air bearings laterally toward and away from one another. Each element carries an inflatable bladder for lifting a load. A rack is also provided for receiving various loads, for example, automotive vehicles. The elements have cutouts at longitudinally spaced positions such that, upon disposition of the elements below the rack, the elements can be moved laterally away from one another with the cutouts registering with the wheel wells. The bladders may be inflated to lift the rack and load carried thereby for movement into a container. The process may be reversed to remove the rack and load from the container.

A tipping adapter permits a cargo container, which is suspended from a hoisting device, such as a gantry cantilever crane, to be selectively tipped about an axis extending longitudinally through the container so that bulk material, such as coal, grain, etc. , may be tipped from the container into a ship's hold or other receiving space. The adapter includes a drive support frame which connects to the crane or a crane-supported container spreader at the connection points normally used in connecting the container to the spreader. A pivotal frame connects to a container in the same manner in which the spreader connects to the container. The drive support and pivotal frames are pivotally engaged so that one or more drive motors, mounted on the drive support frame, can be used to selectively pivot the pivotal frame and thereby tip the container. Controls are placed at the crane control panel to permit selective container engagement and tipping, and interlocks are provided to prevent tipping of the container before it is properly engaged.

Fingers having air bearings along the bottom thereof are used to quickly load and unload overseas transport containers. Sheet material, such as ribbed plastic (nylon) sheeting, is automatically dispensed between the fingers and loading deck so that it provides a smooth surface as the finger traverses the dock. A frame is mounted to the front of the finger, with a shaft on which the sheet material is coiled mounted to the frame, and an air motor for applying a generally constant tension (e. g. about 10 lbs. per square inch) to the plastic sheet. A hook or magnet is mounted in a recess in the deck and engages the free, leading end of the sheet material to hold it stationary on the deck as the finger traverses the deck, and thereby provide for automatic dispensing and take up of the sheet material.

A method and assembly provide for the quick and effective one step loading and unloading of an overseas transport container, which can be accomplished by one operator and a minimum of effort. First, second, third, and fourth identical fingers each about 20' long have a plurality of air bearings associated with them, the air bearings connected up to a source of air under pressure. Inflatable load bars are provided on the tops of the fingers. At the first ends of the first and second fingers they are connected to a structural cross-member which is integral with a manifold for supplying air under pressure to the fingers for inflating the air bearings, and also mounts air-supplying structure for inflating the load bars. The third and fourth fingers are continuations of the first and second, and are utilized when loading or unloading a 40' container. During use the air bearings are inflated, the fingers are simultaneously moved underneath the pallet, load bars are inflated to lift the pallet off of the horizontal surface on which they are resting, the pallet is moved--utilizing a powered hand truck connected to the structural cross-member--into or out of the transport container, the load bars are deflated, and the fingers are simultaneously withdrawn from underneath the pallet.
