Length determination of working cycle of excavators at different technologies of working operations at the construction sites and the correctional proposal coefficients for calculation of real productivity.

In the bachelor´s thesis are stated values of working cycles of excavators at different technologies of working activity at the construction. Based on the basis of data and observing working technologies, the worked up proposal reflects correcting coefficients for calculation of real productivity. The study contains analysis of working materials of machines for ground work, analysis of fundamental kinds of ground works on construction states, analysis of excavator shovels and analysis of excavators working tools. In the second part, there are factors that influence productivity and there are determined remedial coefficients for calculation a real productivity. Further, in this thesis are compared of theoretical and real productivity observed by excavators. The results compare different excavator categories according to their size. In the ending of this thesis, there are determined the proposals and the principles for optimal usability of excavators at the construction
