The purpose of this study is to evaluate environmental impacts from the manufacturing process of excavators by using LCA, and improve design and manufacturing process. This study was analyzed by each process through characterization and normalization. The result shows that assembly and fabrication process has the highest environmental impact on Abiotic Resource Depletion, Global Warming, Photochemical Oxidant Creation, while painting and finishing process has the highest environmental impact on Ozone depletion, Eutrophication, and Acidification. This shows that environmental impact of manufacturing excavators came from using much steel and energies in accordance with the usage. Therefore, recycle of steel and development of new material is important for sustainable construction equipment industry.
