A pin assembly for a piston block of a hydraulic cylinder includes a pin that is axially engaged with the piston block. The pin assembly also includes a floating bush that is spaced apart from the pin to receive a sleeve therebetween. The floating bush is also configured to exhibit axial and radial play in its movement relative to the sleeve. The axial and radial play in the movement of the floating bush allows the floating bush to align with a cap port of the cylinder housing prior to entering the cap port of the cylinder housing.

Methods and systems for operating an industrial machine. One system includes a controller that includes an electronic processor. The electronic processor is configured to calculate an eccentricity of a center of gravity of the industrial machine with respect to a center of a bearing propelling the industrial machine and calculate a ground pressure associated with the bearing based on the eccentricity of the center of gravity. The electronic processor is also configured to set a maximum torque applied by an actuator included in the industrial machine to a value less than an available maximum torque based on the eccentricity of the center of gravity and the ground pressure.

Systems and methods for compensating dipper swing control. One method includes, with at least one processor, determining a direction of compensation opposite a current swing direction of the dipper and applying the maximum available swing torque in the direction of compensation when an acceleration of the dipper is greater than a predetermined acceleration value. The method can also include determining a current state of the shovel and performing the above steps when the current state of the shovel is a swing-to-truck state or a return-to-tuck state. When the current state of the shovel is a dig-state, the method can include limiting the maximum available swing torque and allowing, with the at least one processor, swing torque to ramp up to the maximum available swing torque over a predetermined period of time when dipper is retracted to a predetermined crowd position.

A ground engaging tooth for a ground engaging machine is disclosed. The ground engaging tooth may comprise a non-ground-engaging end, a ground-engaging end, a body extending between the non-ground-engaging end, the ground-engaging end, a top surface, a bottom surface, a left surface and a right surface. Further, the ground engaging tooth may comprise a coupling side including a pocket configured to receive a retaining device. Moreover, the ground engaging tooth may comprise a wear side including an integral-wear-insert. The integral-wear-insert may longitudinally extend along the bottom surface towards the ground-engaging end and vertically extend towards the top surface at the ground-engaging end.

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.

A method of determining a payload mass, the method comprising receiving rope data indicative of the rope force from the rope force sensor, receive position data indicative of the current shovel position from the one or more position sensors, determine a payload mass based on the rope force, the current shovel position, and a defined relationship between a kinetic energy of the mining shovel, a potential energy of the mining shovel, one or more degrees of freedom of the mining shovel, and one or more forces experienced by the mining shovel, and provide the payload mass to a display device associated with the mining shovel.

An excavator comprises a chassis, an implement, and an assembly comprising a boom, a stick, and a coupling. The assembly is configured to define a heading {circumflex over (N)} and to swing with, or relative to, the chassis about a swing axis S. The stick is configured to curl relative to the boom about a curl axis C. The implement is coupled to a stick terminal point G via the coupling and is configured to rotate about a rotary axis R such that a leading edge of the implement defines a heading Î. An excavator control architecture comprises sensors and machine readable instructions to generate signals representative of {circumflex over (N)}, an assembly swing rate ω.sub.S about S, and a stick curl rate ω.sub.C about C, generate a signal representing a terminal point heading Ĝ based on {circumflex over (N)}, ω.sub.S, and ω.sub.C, and rotate the implement about R such that Î approximates Ĝ.
