A replaceable guide rail for a crawler includes a base that has a flange. The replaceable guide rail further includes a hole extending laterally through the flange that is configured to receive a fastener to secure a portion of the crawler to the flange, a guide member extending along the centerline and being configured to contact a track portion of the crawler and be worn down during movement of the track portion over the guide member, and a wear indicator positioned in the guide member configured to indicate whether the guide rail is in condition for replacement. The guide member has a thickness that is reduced as the guide member is worn down. The wear indicator is covered while the thickness is in a first range of thickness, and the wear indicator is exposed while the thickness is in a second range of thickness.

A mining machine includes a frame having a guide rail, the guide rail having a central portion. The mining machine also includes a shoe having a recessed area that defines a roller path, the shoe further having a drive lug, wherein the central portion of the guide rail is configured to be disposed within the recessed area. The mining machine also includes a cutting tool coupled to the frame and positioned such that the cutting tool is configured to abrasively remove material from the drive lug as the drive lug passes by the cutting tool.

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.

An industrial machine includes a frame having a base and a boom, an arm movably coupled to the boom, an attachment, a conduit, a first member, and a second member. The boom has a first end coupled to the base and a second end opposite the first end. The arm includes a first end and a second end. The attachment is coupled to the first end of the arm. The conduit extends from the frame to the arm. The first member is pivotably coupled to the frame and supports a first portion of the conduit as the arm moves relative to the boom. The second member is pivotably coupled between the first member and the arm, and supports a second portion of the conduit as the arm moves relative to the boom.
