The time within which, accordingly to its application, machine works, and an object of work and working groups are under load, is the effective active time. The purpose of the research was the order statistics of effective active time of limbing and conversion at chainsaw use in two technology and two habitat variants. The effective active time of limbing and conversion of one tree was most frequently...
The time within which, accordingly to its application, machine works, and an object of work and working groups are under load, is the effective active time. The purpose of the research was the order statistics of effective active time of limbing and conversion at chainsaw use. The removed trees were moderately diversified from the point of view of effective active time of limbing and conversion. The...
The time, within which accordingly to its application machine works, and an object of work and working groups are under load,is the effective active time. The purpose of the research was the classical and order statistics of effective active time of felling at use chainsaw. The average effective active time of felling of one tree was about 2 s. The cut trees were strong statistical diversified from...
The wood chips (product of chipping) can be assigned for production of particle and fibre boards. The object of the performed investigations was to determine fractions of industrial wood chips. The chips were harvested with chippers of various kinds. The determination of chips fractions was based on 5 fraction classes. In all the samples, fraction 10-35 mm was the most numerously represented. For...

W krajach europejskich podstawowym surowcem tłuszczowym jest olej rzepakowy, ale jego potencjalne zasoby są ograniczone, gdyż uprawa rzepaku wymaga określonych warunków klimatycznych i glebowych. Praca poświęcona jest badaniom nad lnianką siewną (Camelina sativa L.), zapomnianą rośliną oleistą, której historia uprawy na ziemiach Polski sięga czasów kultury łużyckiej. Roślina ta jest stosunkowo mało...
Jednym z rozwiązań technologicznych pozyskiwania surowca drzewnego jest stosowanie maszyn wielooperacyjnych. Obok pojawiających się już dość powszechnie w naszych lasach harvesterów i forwarderów można spotkać, choć jeszcze stosunkowo rzadko, harwardery. Przedmiotem badań było określenie struktury czasu i wydajności pozyskiwania i zrywki drewna przy użyciu harwardera Buffalo Dual firmy Ponsse. Na...
