A loading machine having two rotatably connected scoops. One of the scoops is, in one of its end positions, received in the other scoop and is thereby directed in the same direction as the other scoop.
Claims6
A method of loading, transporting and discharging material obtaining increased capacity comprising:
- positioning a scoop to be nested within a load bucket connected to arm means pivotally connected to a load transporting vehicle,
- raising and lowering the arm means for selectively positioning the load bucket,
- steering the load bucket and scoop therein toward the material to be loaded and loading material into the scoop,
- raising the scoop to a raised position by raising the load bucket to a selected position, retaining the scoop in the raised position while lowering the load bucket to unnest the scoop from within the load bucket,
- loading material into the load bucket, and transporting the loaded material and discharging the same from the scoop and from the load bucket.
