Analysis of the operation of multi-operational forestry machines in the conditions of the North-Western Federal district

The analysis of the reporting data of multi-operational forestry machines is an important and relevant area of research in the field of the timber industry, which makes it possible to competently regulate production and increase the efficiency of logging. This article examines the efficiency of multi-operational forestry machines in relation to the typical conditions of the North-Western Federal District. In the course of the study, the dimensional parameters of the grades harvested using felling, knot-cutting and bucking machines based on Caterpillar and Komatsu tracked excavators with a LogMax 6000 harvester head equipped with Parker Motomit IT 6.5 onboard computers and carrying out logging operations in the Leningrad Region and the Republic of Karelia were studied. The reporting data of logging operations in the Volkhov, Lodeynopolsky, Podporozhsky and Olonetsky forestry districts were analyzed.  To analyze and visualize reporting data from on-board computers of multi-operational forestry machines, a Python program has been compiled that allows processing data arrays from files downloaded from on-board computers in stm format, systematizing the data obtained, calculating statistical characteristics of the analyzed machine operation parameters, and visualizing them in the form of diagrams and graphs. It has been established that coniferous wood is mainly harvested in the considered forestry areas of the NorthWestern Federal District. In some cases (for example, in the Lodeynopolsky forestry), the harvesting of hardwoods, including illiquid and low-quality wood, prevails. In most forestry areas, sawn timber is harvested. The distribution of softwood bucking schemes varies significantly by region. The Volkhovsky district is distinguished by the harvesting of a significantly large proportion of trunks with several sawn grades, whereas in the Lodeynopolsky and Podporozhsky districts balance grades are more often produced.
