Dipper handle pin for Bucyrus 4100XPCAC

The dipper handle pin C117579-49 serves as a pivot point for the dipper handle assembly on large electric mining shovels. By acting as a structural axis, it facilitates the relative movement between major components of the digging arm while supporting significant shear and bending forces during excavation cycles. This component is engineered to maintain structural alignment within the shovel's front-end linkage system.

This pin is designed for use in Bucyrus 4100XPCAC, 7495HR2, P&H 4100XPCAC, and P&H 7495HR2 mining machinery. It is manufactured to meet the specific dimensional requirements for these shovel models, ensuring proper fitment within the articulation points of the dipper handle. The part is intended to interface with corresponding bushings to manage rotational movement under the heavy loads characteristic of surface mining operations.

In heavy machinery, pins of this type function as the primary connection points in articulating joints. They are installed to secure moving sections of the boom and dipper assembly, allowing for the controlled motion necessary for digging and material handling. Regular inspection and lubrication of these pins are necessary to manage the mechanical stresses applied to the shovel's structural frame.
