Jul 13, 2015 · Purpose – Excavator productivity calculations embrace myriad variables, which in turn, can be modelled in several ways. A key productivity variable is operator competence ( O c ) because this can impact on so many of the other variables. Earlier research has studied excavator productivity, but little has attempted to simultaneously model productivity variables in relation to O c . The

The present review provides brief information about the excavator arm mechanism. The use of aluminum alloy material in excavator arm can increase the volumetric capacity of the bucket. In this paper, it is proposed to study the concept of finite element method and its application to the excavator arm design. As the present mechanism used in excavator arm is subjected to torsional and bending
