Balancing the excavator structure is a widely considered topic that directly relies on the operation, the wear of nodes connecting the upper and the lower structures of the excavator and especially on the stability of the excavator at the operational site. The present paper considers the balance of the excavator structures of the SRs 2000 excavator with idealization to some static positions and simplification of the interactions to static ones. This allows positional regard of the most used positions under operating conditions. This approach derives some dependences clarifying the static balancing of the super structure of the excavator to the undercarriage, taking into account the interactions of both the weight parameters, as of the structural units, as of the main external forces. There are derived dependences for determining the load of ballast weights during repair and modernization of excavator structures
