The review of feller-delimber-buncher (FDB) “Ponsse Ergo” (element of sorting (Scandinavian) technology of timber harvesting) in natural-production conditions of the enterprise “Mobile Service” LLC (Syktyvkar, Komi Republic) is carried out in the article and modernisation of the hinge joint by installation of expander pins of new design is proposed. The design of the articulated joint of the pivoting system of FDB “Ponsse Ergo” half-frame is considered, on the basis of which the information about the advantages of the expander pin over the cylindrical axial pin is obtained. The design of the expander pin of a new type is presented on the basis of the made and given calculation for the strength of the axial pin of the pivot joint attachment. The hinge joint of the half-frame pivoting system is presented, the axial expander pin of a new design is proposed, the course of dismantling of the cylindrical axial pin of the hinge joint of the known design is presented, followed by the sequence of installation of the expander pin of the new proposed design. Strength calculation of the hydraulic cylinder mounting pin, strength calculation of the axial pivot pin, strength calculation of the connecting bolts are given. The possibility of scaling the solution in the conditions of the Russian Federation is estimated. Advantages of the expander pin over the cylindrical axial pin are given. The results of comparison of cylindrical pin and expander pin of new design are given. As a result of research, the increase of productivity of FDB “Ponsse Ergo” at the expense of increase of inter-service interval and reduction of downtime at the expense of reduction of time required for service maintenance of the unit (preparatory works, main works) is made. Economic indicators of the proposed solution are given.
