Abstract: The machine comprises an endless bucket train which is supported by four wheels. The bucket train passes over the first wheel, under the second, over the third, and over the fourth wheel. Between the fourth and first wheels the bucket train hangs freely and is adapted to dig and transport a wide variety of granular materials. The bucket train comprises circular buckets with axial cables extending therebetween. The material is dumped from the bucket train as it travels downwardly between the first and second wheels. The second and fourth wheels are displaced in opposite directions from the first and third wheels so that the material will be dumped at a point which is clear of the upward flight of the buckets. The fourth wheel is mounted on a boom which is swingable about an axis corresponding generally to the axis of the third wheel so that the elevation of the fourth wheel can be changed. The third and fourth wheels are generally in the same plane, while the first wheel is in a different plane, generally parallel to the plane of the third wheel but converging at a small angle toward the fourth wheel. The second wheel is in a plane which is generally perpendicular to the plane of the third wheel. The entire machine is adapted to be suspended from a crane, for use in unloading ships or the like.
