Abstract: A damper for dampening rotation of a dipper door relative to a dipper body of a mining shovel includes a shaft, an arm, and a high pressure fluid seal. The shaft supported for rotation about a shaft axis, and rotation of the shaft is dampened by fluid in an enclosed chamber. The high pressure fluid seal engages an outer surface of the shaft at a position between the first end of the shaft and the second end of the shaft. The high pressure fluid seal engages an outer surface of the shaft and includes a low pressure side and a high pressure side adjacent a shaft cavity. The arm includes a first end coupled to the first end of the shaft, and a second end coupled to the dipper door or the dipper body such that rotation of the dipper door drives the arm to rotate the shaft.

Abstract: Methods and systems for detecting heavy machine wear. One system includes a heavy machine tooth of an industrial machine having a working end and a mounting end opposite the working end. The system also includes a wear indicator included in the tooth. The wear indicator includes a conductive tip, a conductive outer body extending along at least a length of the tooth, a conductive inner core positioned within the outer body, and insulating material positioned between the outer body and the inner core. The conductive tip is positioned between the working end of the tooth and the outer body and electrically couples the outer body and the inner core to form an electric circuit. The system also includes a transmitter included in the tooth. The transmitter transmits a state of the electric circuit.

Abstract: A tooling system includes a dipper having a lip with a plurality of apertures, the apertures extending at least partially through the lip. The tooling system also includes a modular adapter configured to be inserted partially into one of the apertures along an axis of insertion. The adapter is configured to be releasably coupled to the lip. The adapter includes a first portion configured to extend into the aperture, and a second portion configured to extend out of the aperture. The tooling system also includes a locking system including a fastener configured to extend at least partially into the aperture and couple to the adapter to the lip.
