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.

A method for determining stability of a vehicle having a load suspended from the vehicle is provided. The method can include obtaining measurements from a plurality of sensors positioned on the vehicle, obtaining a measurement from a vehicle accelerometer operative to determine an inclination of the vehicle, determining a position of the load suspended from the vehicle, determining a slung load of the load suspended from the vehicle, using the determined slung load and the determined position of the load suspended from the vehicle, determining tipping moments acting on the vehicle, determining righting moments acting on the vehicle and determining a tipping stability based on the determined tipping moments and determined righting moments.

Embodiments described herein provide systems and methods for generating a three-dimensional virtual track model. This track model may be used, for example, in collision prevention and mitigation systems and methods, such as those described herein, and in other collision prevention and mitigation systems and other mining systems using virtual track models. In some embodiments, the systems and methods described herein provide a simplified modeling process that enables quick, accurate modeling of tracks of a mining machine that can account for custom tracks that vary in size depending on the particular mining machine.

Embodiments described herein provide systems and methods for preventing and mitigating collisions between components of an industrial machine. The industrial machine includes an electronic controller, having an electronic processor and a memory, that is configured to receive dipper position data indicative of a position of the dipper and determine a distance between the dipper and tracks of the industrial machine based on the dipper position data. The electronic controller is further configured to set a motion command limit for a dipper motion based on the distance, the dipper motion being selected from a group of a swing motion, a crowd motion, and a hoist motion and control the dipper motion according to a dipper motion command limited by the motion command limit.

The present invention concerns a dipper assembly and parts thereof for use with a mining shovel. The dipper assembly includes: a dipper body having a back wall and an open dipper bottom; a dipper door pivotally coupled to the back wall of the dipper body and moveable between open and closed positions relative to the open dipper bottom; and a latch assembly for releasably securing the door in the closed position. The latch assembly includes a latch keeper and a latch member for engaging the latch keeper. The latch keeper is associated with the dipper body proximate the open dipper bottom and the latch member is coupled to the dipper door. The latch member includes at least one roller to assist the latch member in engaging and disengaging with the latch keeper and to reduce wear on the latch member.

Embodiments described herein provide for the control of an industrial machine dump operation by monitoring a position of the piston within a dump cylinder. The position of the piston is determined using a sensor within the dump cylinder. The sensor generates and provides an output signal to a controller. Based the output signal from the sensor, the controller is configured to limit the travel of the dump cylinder during the dump operation to reduce wear on the dump cylinder (e.g., by preventing damage caused when the dump cylinder is extending or retracting rapidly and the internal cylinder components make forceful contact with the rod or cap end).
