ABSTRACT:
Excavating apparatus including a boom having an idler pulley on its outer end and adapted to carry a digging chain in sliding arrangement with the boom is provided with skid shoe means and a nose piece which are disposed between the idler pulley and the outer end of the boom for slidably engaging and supporting the digging chain between the idler pulley and the lower surface of the boom. The skid shoe means defines a support surface that is substantially coplanar with the lower surface of the boom to support the links of the chain, and the nose piece has a lower surface generally parallel to the lower surface of the boom and is adapted to engage the digging chain rollers when the links of the chain are engaging the skid shoe means. Both the skid shoe means and the nose piece thus prevent the chain from causing excessive wear on the end of the boom.
