An eco-approach to optimise efficiency and productivity of a hydraulic excavator

摘要: The depletion of fossil fuel and the ozone layer has been a global concern for decades. International Organization Standardization published earth-moving machine sustainability standards industry to provide information satisfy their customers' interests in construction projects. Furthermore, steeply rising energy prices collapse financial institutions recent years have sparked demand ways improve individual efficiency. Original equipment manufacturers machines must address requirements, as well remaining competitive they aim do this by improving efficiency, adopting advanced fleet management systems, providing operator training courses etc. Clearly high efficiency is important reduce fuels damage environment. However, objectives achieving highest possible productivity (m3/h) (kg/l) are often considered separately. Many equations formulated measure machine's level, yet there lack consensus between academia sources on terms which should be within such equations. Perhaps more importantly, none explicitly relationship productivity, only scant consideration given role operators optimum Therefore, paper presents an eco-approach enable achieve optimal hydraulic excavator. Hydraulic excavators primarily designed excavating with bucket. Their ease use, versatility won them major segments market, therefore focus exactors justifiable. research presented adopted applied methodology collect measurable, empirical evidence through scientific experiments order test several hypotheses that reduction GHG produced machines. examined two variables, engine speed bucket cut depth, determine effects experimental results show combinations various settings depths can increase 30% greenhouse gas emissions 24%, consequentially moving 62% spoil every hour litre consumed. also suggest identifying correct depth key significant improvements emissions. concludes adoption appropriate operation style help associated excavators. Hence, educating select right cost effective approach lowering operational costs carbon lower consumption greater longevity.
