The State Forests National Forest Holding that manages 77.1% of the forests in Poland intend to harvest over 40 million m³ of timber, which is supposed to supply the demand from some thousand timber processing companies. Introduction of a new normative for determination of the timber load weight as a result of multiplication its volume and wood density significantly changed timber transport regulations...
Timber hauling from the forest, either directly to the consumer or to the place of transshipment for a rail transport, is carried out by vehicles adapted to the transport of long or short logs and medium−sized wood. In Poland, regulations restrict the total weight of a vehicle traveling on roads, which consists of the weight of the empty vehicle and the weight of the load. When transporting the wood,...
Since many years much attention has been paid to the rationality of wood transportation criteria due to the realization of social objectives. Identification and elimination of unnecessary haulage can reduce the total cost of transport and contribute to reducing fuel consumption, carbon dioxide emissions and accident risk. This paper concerns decision support for the allocation of available wood as...
Analizie podano podstawowe wskaźniki techniczno-ekonomiczne dwóch samochodów do wywozu drewna. Określono wydajność oraz bezpośrednie jednostkowe koszty wywozu.
Określenie charakterystyki obciążenia drogi wiąże się z analizą ilościową i jakościową poruszających się po niej pojazdów. Celem pracy było określenie rzeczywistych obciążeń powstałych na osiach zestawu przy transporcie drewna. W pracy przedstawiono wyniki analizy parametrów zestawów do wywozu drewna: masy całkowitej zestawu (GVW), obciążenia poszczególnych osi, jednostkowych ładunków mas drewna....
