Abstract
Heavy mining equipment like dumpers dozers shovels are considered to the back bone of the industries. Majority of the production is completely relying upon this heavy equipment. So for obvious reason the periodic maintenance is considered to be one of the most important concerns for the industries. In this work the Atomic Emission Spectroscopic (AES) analysis has been done for 15W40 Engine oil used in a Komatsu 785 100 Ton capacity dumper. From the analysis the wear particle suspended in the lubricant has been analyzed and counted in terms of ppm. From these wear particle analysis the part which is under abnormal wear condition has been figured out. For the test purpose used lubrication oil has been collect ted at seven different hours of operation and the results of all these seven different hours has been compared.
