Study on the relationship between stability and energy efficiency of hydraulic excavators

Abstract

The cycle of operation of hydraulic excavators has a series of steps in which large masses are accelerated and then braked. The presence of additional masses on the excavators improves stability but reduces energy efficiency. In this paper is examined the possibility of reducing energy consumption while maintaining an acceptable stability of the machine. The results of the analysis allow for some conclusions on how to achieve energy efficiency on the excavators.
