Abstract
Spotlight is on common patterns in linear parameters of electric and hydraulic shovel implements and biomechanics of higher verterbrates. Using the fundamental composition concept of robotic biomechanical systems, connected with the three-tier structure and stable ratios of their link lengths, proportions of shovel implements were analyzed and their correlation with the human hand is demonstrated. The forms of symmetry, based on prime relations and wurf, are found, materialized in the mechanism irrespective of an engine type and a bucket capacity. The influence of the ratios of link lengths on the technical characteristics of implements and productivity of the machines is shown. the research findings point at the further improvement trends for the mining shovels using the principles of mechanics and physiology of movement of living organisms, and open up new opportunities in the field of geometrical synthesis of shovel implements.
