Abstract
An improved eccentric used in walking mechanism sub-assemblies used in heavy equipment, specifically drag line excavators. The walking assemblies include a power driven output shaft which engages and rotates an eccentric fitting journaled within a leg housing which is in turn pivotally secured to the walking assembly shoes and through a support linkage to the excavator frame imparting a modified elliptical travel path thereto. The improvement is directed to the eccentric which is of a multiple component fabrication for increased performance and use durability and extended life.
