Abstract: A cutting assembly for a mining machine includes a mount configured to move about a first axis relative to a chassis of the mining machine and a ranging arm coupled to the mount. The ranging arm is moveable relative to the mount. The cutting assembly includes a cutting head having a housing coupled to the ranging arm. The housing is moveable relative to the ranging arm. The cutting head includes a drum supported for rotation relative to the housing about a rotational axis, a plurality of cutting bits coupled to the drum, and at least one motor supported by the housing to drive the drum about the rotational axis.

Abstract: An industrial machine including a sensor and a controller. The sensor is configured to sense a characteristic of a fluid of the industrial machine. Wherein the characteristic is indicative of a contaminant level. The controller has an electronic processor and a memory. The controller is configured to receive a signal from the sensor indicative of the contaminant level, compare the contaminant level to a threshold, and upon the contaminant level crossing the threshold perform at least one selected from a group consisting of output an alert, and commence a shutdown procedure of the industrial machine.

Abstract: A system for guiding movement of a chassis of a mining machine along a rack includes a shoe and a fluid line for receiving fluid from a fluid source. The shoe is configured to be coupled to the chassis and slidably engage the rack. The shoe is configured to extend at least partially around the rack. The shoe includes a first end, a second end, an inner surface, and an outer surface. At least a portion of the inner surface is configured to be positioned adjacent the rack. The fluid line includes an outlet positioned proximate the shoe for dispensing the fluid at an interface between the shoe and the rack.
