Abstract
O objetivo deste trabalho foi avaliar técnica e economicamente o forwarder em três subsistemas de colheita em florestas de eucalipto. A análise técnica englobou um estudo de tempos e movimentos e de produtividade. A análise econômica englobou os parâmetros custo operacional, custo de produção e rendimento energético. O elemento carregamento abrangeu mais de 80% do tempo total, em todos os subsistemas. Os tempos dos elementos viagem vazio e viagem carregado foram influenciados principalmente pela distância média a ser percorrida. Chegouse ao custo operacional de US$60,70/he. Os custos de produção do forwarder foram de 1,74, 1,53 e 2,51 US$/m3cc, nos subsistemas 1, 2 e 3, respectivamente; e o rendimento energético foi de 2,76, 2,42 e 3,98 g/kW*m3cc, nos subsistemas 1, 2 e 3, respectivamente.
This work aimed to evaluate a forwarder, technically and economically, under three eucalyptus forest harvest subsystems. The technical analysis included a productivity and motion and time study. The economic analysis included the parameters operational cost, production cost and energy consumption. Loading consumed more than 80% of the total cycle time in the subsystems studied. The average travel distance influenced unloaded and loaded travel times. The forwarder's operational cost was US $ 60.70/ha. The forwarder production costs were US$ 1.74 , 1.53 and 2.51 /m3cc, in subsystems 1, 2 and 3, respectively. The energy consumption rates were 2.76; 2.42 and 3.98 g/kW*m3 cc, (FORMATAR )in subsystems 1, 2 and 3, respectively.
