A fluidized aggregation separation system including an intake assembly having a first and a second end, and a separation assembly configured to separate material larger than a predetermined size from material smaller than the predetermined size. The separation assembly includes a screen assembly configured to prevent the material larger than the predetermined size from passing through the screen assembly and to allow the material smaller than the predetermined size to pass through the screen assembly. The fluidized aggregation separation system also includes an exit assembly configured to direct the material smaller than the predetermined size towards a restoration area,

An offloading vacuum system. The system has a tank to capture debris from an excavation site. The debris is pulled into the tank due to a blower pulling air into an attached hose. An internal conveyor within the tank conveys material to an offloading hub. The offloading hub has a ground-facing door which opens to deposit debris into an external conveyor. The external conveyor, when deployed, can move debris from below the tank to a dump container with a wall greater than a height of the tank.

A system and method for various levels of automation of a swing-to-hopper motion for a rope shovel. An operator controls a rope shovel during a dig operation to load a dipper with materials. A controller receives position data, either via operator input or sensor data, for the dipper and a hopper where the materials are to be dumped. The controller then calculates an ideal path for the dipper to travel to be positioned above the hopper to dump the contents of the dipper. In some embodiments, the controller outputs operator feedback to assist the operator in traveling along the ideal path to the hopper. In some embodiments, the controller restricts the dipper motion such that the operator is not able to deviate beyond certain limits of the ideal path. In some embodiments, the controller automatically controls the movement of the dipper to reach the hopper.

A soil spreading scraper device has a cutting blade to cut soil from the ground and a rotating impeller member for spreading the cut soil as the frame is displaced forwardly. The impeller member includes a main disc body and a plurality of impeller blades on the main disc body which are pivotal relative to the body between a working position in which the blade body extends in a direction of the impeller axis away from the main disc body and a deflected position in which the blade body extends in a circumferential direction of the disc body in a trailing relationship relative to the pivot axis of the blade body. An actuating assembly resists displacement of the blade body into the deflected position until pressure on the paddle exceeds a prescribed holding force. A spring biases the body to return to the working position.

Machine, especially a padding machine, for the burying of pipes, in particular arranged in a respective excavation of the ground, quali gas pipelines, oil pipelines, aqueducts, or altri, in particular for la covering of said pipe with a corresponding material, in particular un treated material, preferably screened or frantumato, including a main support framework of the apparatus, in particular which extends according to a respective longitudinal axis of the same machine, a cabin for housing the driver of the machine, such a cabin is in the form of a cabin movable with respect to said main support frame. Said cabin for housing the driver of the machine can be positioned, in corresponding vertical positions, or placed at height levels different from each other, preferably moving vertically, or perpendicularly to said ground.

A floating filtering apparatus is used to separate solid material in a slurry by size, so that the filtered slurry and/or solid material that has been separated from the slurry can be further processed. The floating filtering apparatus comprises a filtering assembly, a first submergible tank, a first pump, and a receptacle for secondary material. The floating filtering system is contained in or supported by a vessel that floats on water and can move and/or be moved about on the surface of the water.

Systems and apparatus for improved spoils collection and extended machine life for ground cutting machinery. In some embodiments, a housing for ground cutting machinery, such as a microtrencher, has a collection port formed therein. The bore of the collection port may be aligned with the direction that spoils are ejected from the ground cutting blade. The collection port may have a lower portion formed by the housing and a removable upper transition assembly formed as a tube and including an upper coupling for connection to the vacuum collection system. A replaceable sacrificial plate is disposed within the upper transition tube. The sacrificial plate bears the impact of spoils exiting the housing into the vacuum system. As wear occurs, the sacrificial plate may be removed and replaced.
