  • Patent number: 5503082
    Abstract: A concrete-embedded, machinery-anchoring floor system includes parallel, accurately-extruded steel rails each having a unique cross-sectional configuration. Vertical loading of the rails improves the load-bearing strength of the concrete, whether the loading is in tension or compression. Each rail includes a pair of spaced angularly-extending, outwardly and downwardly-projecting flanges. When a downward compressive load is applied through the rails from above, the load also applies downward and inward force vectors generally perpendicular to the angular flanges, compressing concrete therebetween. If tension is applied to a rail from a cantilevered load, the angular flanges are fulcrumed toward each other about their connecting joints with the rail, also compressing and strengthening concrete therebetween. The angular flanges are rounded at their distal edges to enable supporting and interconnecting reinforcing bars to be easily welded to the rounded edges, irrespective of the angle of the bars to the edges.

  • Patent number: 4190393
    Abstract: Trailers are loaded on and unloaded from railroad flatcars by use of a system including tractors to pull the trailers, an end ramp at the end of the train, and a movable side ramp structure at the side of the train. The movable ramp structure has a ramp and a retractable bridge extending from the top of the ramp to the top of a flatcar in the train. In unloading, a tractor drives up the movable ramp and across the bridge to get onto the flatcar. Then the bridge is retracted, the tractor hitches onto one of the trailers, and pulls it along the joined beds of the flatcars and down the end ramp. The tractor then takes the trailer to a storage area, unhitches the trailer, and returns to the movable ramp structure to repeat the process. While the first tractor is pulling the trailer along the tops of the flatcars, the movable ramp structure moves to a position near the next trailer to be unloaded, and extends the bridge again.

    Abstract: This invention is a loader-unloader and storage system for loads such as cargo containers or trailers to transfer them to or from trains or vehicles moving by. This loader has a lift frame with forks or hooks for engaging under to hold a load. The frame is pivotally secured on a plurality of parallel crank arms each mounted to rotate on a vertical pivot to form a parallelogram linkage. The arms are supported on wheels that run on a circular track concentric under each crank arm. The track has slopes to lift and lower the arms together according to the rotary position of the arms and track to transfer loads to or from a vehicle having side latches coupled the the forks, the frame, or the load. A load receiver cooperates for removing loads from the lift frame nonstop so the loader can be used to unload or load successive loads. One receiver is a conveyor having two chain runs which receive the load from the loader and move the load back to clear a place to set the next load thereon.

  • Patent number: 4090620
    Abstract: General cargo must be stowed differently when being transported by ships, or by railway waggons and trucks, respectively. To reduce the time a ship is tied up in port, a transhipping station is provided, where work can proceed before the ship arrives and after the ship has left port. This station is arranged so it is available along one side to railway waggons carried by special transport devices, remotely from railway tracks, at a second side is available to cargo-bigflats, suited for cargo handling on board ships, and possibly also, along a third side, being available to road trucks.
