ABSTRACT
The wearing process of fitting of attachment of dredging scoops from steel 110Г13 at shock-abrasive influence is connected with low mechanical characteristics of metal which slightly increase at operation. Durability rise provides increase in initial hardness of bushings and pins from 200 to 380 НВ.
