Abstract
The purpose of the work is to supplement the existing GOST 30067–93 with the key parameters of a single–bucket excavator – the power of the power plant Nэ and the capacity of the main bucket q at a given operating weight of the excavator mэ , which must be known during design and which characterize its energy flow during soil development. Based on the “Einstein equivalence principle”, the physical principles of the structure of the energy flow when digging the ground with a single-bucket excavator are formulated. Its operators are introduced – the energy intensity (power) operator CN and the operator of the excavator development Cq . Analytical formulas for their calculation were obtained and their statistical evaluation was carried out for 67 domestic and 36 foreign models of excavators.
