A dipper lip includes a first side wing, a second side wing, a rear attachment portion that spans from the first side wing and the second side wing, and a front shovel portion that extends from the first side wing to the second side wing, and the front shovel portion defines a top shovel surface, while the rear attachment portion forms a top rear surface. The top shovel surface forms an obtuse angle with the top rear surface in a midplane of the dipper lip.

An excavation system may include a base unit, a boom mounted on the base unit, a pair of drag ropes coupled with the boom, and a robotic bucket mechanism attached to the pair of drag ropes. The robotic bucket mechanism may include an undercarriage drive, a chassis mounted on the undercarriage drive, an excavating bucket mounted on the chassis, a pair of hydraulic lift actuators coupled between the chassis and the excavating bucket at pivot points on both sides of the excavating bucket, and a hydraulic tilt actuator mounted between the chassis and a rear side of the excavating bucket.

Described are a rear taper dragline bucket having a trunnion, a trunnion system, and a trunnion that permit a rear taper dragline bucket to be operated without a spreader bar while providing reduced wear on the trunnion, trunnion link, and trunnion pin.

A tilt adjustable head attachment assembly for a clamshell style bucket for orienting first and second bucket halves at an angle relative to a length axis extending through an elongated and rigid attachment associated with a piece of power equipment, for supporting and manipulating the bucket. A frame has a three dimensional body, upwardly extending pillar mounts located at upper ends of the body and incorporating support shafts for receiving overlapping hinged locations associated with support arms for each of the first and second clamshell bucket halves. A platen is positioned pivotally arranged between the pillar mounts and includes an upper location engaged by an end projection of the elongated attachment. A cylinder is connected to a fixed underside location of the frame at a first end and to the platen at a second end and, upon being actuated, pivotally displacing the platen to in turn angle the frame and supported clamshell bucket halves relative to the excavator attachment according to a desired orientation.

Mining shovel with compositional multispectral and/or hyperspectral imaging and associated methods and systems are disclosed herein. In some embodiments, a mining detection system includes a mining bucket carrying a multispectral and/or hyperspectral imaging system and various sensors directed toward material entering and positioned within the bucket. The bucket can also carry a control enclosure housing image and sensor processing equipment that receives and analyzes the data collected by the multispectral and/or hyperspectral imaging system and the sensors. The disclosed systems and methods can provide real-time compositional analysis of mined materials at the mining site, which can be used to manage a mining field, including generating and transmitting instructions for where the material within the bucket should be delivered based on the data collected from the multispectral and/or hyperspectral imaging system and the sensors.

Self-cleaning sensor window devices for mine site equipment and associated systems and methods are disclosed herein. In some embodiments, a self-cleaning sensor system includes a sensor housing having an opening, a sensor carried by the sensor housing, a self-cleaning window device coupled to the sensor enclosure and positioned at least partially within the opening. The self-cleaning window device comprises a window positioned forward of the sensor to allow the sensor to transmit and/or receive signals through the window, a cleaning assembly directed toward the window and configured to clean debris from the front surface of the window, and a controller operably coupled to the cleaning assembly. The controller can transmit control signals to the cleaning assembly to initiate cleaning of the front surface of the window.
