Company patents

Joy Global Surface Mining Inc

Joy Global Surface Mining Inc's patent strategy reveals a strong, sustained focus on its core "Excavating & Earth-Moving" category, which constitutes 64.4% of its portfolio and saw a significant 66.7% YoY growth in 2024, despite a sharp decline so far in 2026. Surprisingly, while "Drilling & Mining" also saw rapid growth of 300.0% YoY in 2024, the company appears to be shifting away from "Vehicle Steering & Bodies" and "Radar / Sonar / Lidar," both of which experienced a 100.0% YoY decline in patenting activity so far in 2026.

BREAKOUT SYSTEM FOR A DRILL

Filed:2024-07-05Pub:2025-01-09
Applicant:Joy Global Surface Mining Inc

A breakout system for a drill includes a first wrench, a second wrench, and an actuator for applying a torque to rotate the second wrench relative to the first wrench. The first wrench includes a first clamp member for engaging a portion of a drill string. The first wrench further includes an open side and is supported on a mast of the drill in an orientation to permit viewing the first clamp member from an operator cab of the drill. The second wrench is supported for movement relative to the first wrench. The second wrench includes a second clamp member for engaging another portion of the drill string, includes an open side, and is supported on the mast in an orientation to permit viewing the second clamp member from the operator cab. The first and second clamp members may be configured to pivot outward relative to at least one wrench.

Systems, methods, and devices for controlling the operation of an industrial machine based on a pipe attribute

Filed:2021-03-10Pub:2023-12-26
Applicant:Joy Global Surface Mining Inc

Systems, methods, and devices for controlling the operation of an industrial machine (e.g., a drill) based on a determined attribute of a pipe. A sensor is configured to generate an output signal related to a characteristic of the pipe. The characteristic of the pipe can be the presence or absence of a pipe, a weight of the pipe, etc. A controller receives the output signal from the sensor and determines an attribute of the pipe based on the output signal from the sensor. In some embodiments, the attribute of the pipe is a wall thickness of the pipe. In some embodiments, the controller determines the wall thickness of the pipe based on a difference between an initial weight for the pipe and a current or present weight of the pipe. In some embodiments, the controller determines the wall thickness of the pipe based on a difference between an initial diameter of the pipe and a current or present diameter of the pipe. The controller is then configured to control the industrial machine or take a control action based on the attribute of the pipe.
