Efikasnost rada harvestera Komatsu 951G pri seči stabala i izradi drvnih sortimenata na površinama zahvaćenim vetrolomima i vetroizvalama

Abstract

Vetar je u stanju da za veoma kratko vreme šumi nanese velika oštećenja. Štete koje izaziva vetar se manifestuju na različite načine. Razlikujemo: vetrolome, vetroizvale i savijanja. U radu su prikazani rezultati istraživanja efikasnosti harvestera Komatsu 951G tokom seče stabala i izrade drvnih sortimenata u sastojinama topola (Populus x euramericana) klon M-1 zahvaćenim vetrolomima i vetroizvalama. U ukupnom vremenu seče i izrade drvnih sortimenata efektivno radno vreme bilo je zastupljeno sa 79%, dok su zastoji učestvovali sa 21%. Učinak harvestera izražen je u m3 po radnom satu mašine iznosio je 24.48 m3/h. Istraživanjem je utvrđeno da cena harvestera po jednom radnom satu iznosi 82.88 €, dok jedinični troškovi harvestera Komatsu 951G iznose 3.39 €/m3.

The wind is able to cause major damage to the forest in a very short time. The damage caused by the wind manifests itself in different ways. We distinguish windbreaks, windthrows, and bendings. This paper presents the research results on the productivity of the Komatsu 951G harvester in poplar stands (Populus x euramericana clone M-1), affected by windbreaks and windthrows. The share of the effective working time was represented by 79% of total time, while delays share was 21% of the total time of cutting and processing of assortments. The productivity of the harvester was expressed in m 3 per working hour of the machine, it was 24.48 m 3 /h. The research showed that the price of a harvester per one working hour is € 82.88, but the unit cost of the Komatsu 951G harvester is € 3.39/m 3 .
