Systems, methods, and devices are provided 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. The controller is then configured to control the industrial machine or take a control action based on the attribute of the pipe.

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.

A bit changer assembly includes a bit basket actuator assembly configured to be coupled to a drill rig. The bit basket actuator assembly includes an actuator, a guiderail, and a bit basket that is movably coupled to the guiderail via actuation of the actuator. The bit changer assembly also includes a bit carousel configured to be coupled to the drill rig, such that the bit carousel is rotatably and vertically moveable relative to the drill rig.

A mast and rack assembly for a mining machine includes a mast and a rack assembly coupled to the mast. The rack assembly includes outer rails and rack segments disposed between the outer rails and the mast. At least one of the outer rails overlaps two of the rack segments.

Mast with rack assembly

A blasthole drill rig includes a base, a drill tower extending from the base, a drill pipe coupled to the drill tower, a drill bit coupled to a lower end of the drill pipe, an air compressor that directs compressed air through the drill pipe, and a heating element that heats the compressed air.

Combustor for heating of airflow on a drill rig

A mining shovel includes a base for supporting the shovel on a support surface, a boom, an elongated member movably coupled to the boom, and a support member. The boom includes a first end pivotably coupled to the base and a second end positioned away from the base, the boom being pivotable about a boom pivot axis extending transversely to the boom proximate the first end. The elongated member is pivotable about a shaft positioned between the first end and the second end of the boom. The support member biases the boom against pivoting movement about the boom pivot axis, and the support member extends between the base and the boom.
