Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application claims priority to U.S. Provisional Application No. 61 / 605,505, filed Mar. 1, 2012, the entire contents of which are incorporated herein by reference.FIELD OF THE INVENTION

[0002] The present invention relates to lubrication of an industrial machine, and in particular to automatic lubrication of one or more structural elements of an industrial machine.BACKGROUND OF THE INVENTION

[0003] Industrial machines, such as electric rope or power shovels, draglines, etc., are used to execute digging operations to remove material from a bank of a mine. During that process, the machines employ various large mechanical components (e.g., a boom, a boom handle, a dipper, a dipper door, etc.). The industrial machines further include a variety of structural elements (e.g., pins, bearings, bushings, etc.) that connect the various mechanical components and linkages of the machines. Typically, the structural elements are not lubricated during th...
