Cutting stacked wood into length by means of a petrol chainsaw is a typical technical and technological wood harvesting solution. Due to the fact that wood harvesting is most commonly performed with the use of Tree-Length-System (TLS) or Long-Length-System (LLS), cutting into length in Poland is performed either after the first stage of skidding stems or logs to the skidding route or after the second...
The research was conducted in pine stands where selective early and late thinning was carried out with the use of NIAB 5-15 and HYPRO 450 debranching and cutting processors along with a FRANSGÅRD V-6000 GS cable winch aggregated with farm tractors. In case of cut-to-length system, timber harvesting was executed by means of processors and in case of tree-length system – by means of a cable winch. The...
Przedmiotem badań było określenie poziomu uciążliwości pracy związanej z pozyskaniem drewna w selekcyjnych trzebieżach wczesnych i późnych drzewostanów sosnowych. W trakcie zabiegów zastosowano ręczno-maszynową technologię pracy w ramach systemu drewna krótkiego. Ścinka i obalanie drzew były realizowane przez pilarza z kilkuletnim stażem pracy. Do okrzesywania i przerzynki drewna zastosowano procesory...
In the study, impact of three devices aggregated with farm tractors on forest soil was compared – FRANSGARD 6000 GS cable winch and two processors – NIAB 5-15 and HYPRO 450. The basic difference between the above mentioned machines consists in the fact that the cable winch skids debranched tree stems while processors skid the whole trees, including their tree-tops. The percentage of soil injured in...
According to statistical data, today forest services in Poland are performed by over 4,7 thousand private transactors. As a result of the complex process of privatization of the service sector in forestry, after 17 years of its implementation, private enterprises have almost entirely taken over various forest management tasks in the State Forests. The present study is an attempt at showing the influence...
Wobec dużego rozmiaru prac pielęgnacyjnych realizowanych przez Lasy Państwowe niezbędna jest ich mechanizacja, podnosząca wydajność przy niezmienionej jakości wykonania. Poznanie i optymalizacja struktury czasu pracy operatorów wykaszarek spalinowych przy wykonywaniu pielęgnacji upraw ma w tym kontekście duże znaczenie praktyczne. Racjonalizacja technologii pielęgnacji upraw w analizowanym doświadczeniu...
