One of the leading construction equipment, excavators that are used various construction sites. Recently, the demand of large-scaled excavators putting into construction fields for industrial plants has been increased, so that domestic construction-equipment industries are beginning with the production of 85ton-class excavators and putting forth for the localization of their components. Excavators can"t be produced domestically, but the whole quantity is imported from Japan and Italy. To insure a competitive power of the domestic 85ton-class excavators, the localization of the track drive unit is highly required. In this study, an experimental comparative-analysis for main functional characteristics of imported track drive units was carried out, and then technical specifications were investigated, which will be required for the domestic of 85ton-class track deive unit.
