ANÁLISE TÉCNICA E ECONÔMICA DO FORWARDER EM TRÊS SUBSISTEMAS DE COLHEITA DE FLORESTAS DE EUCALIPTO 1

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 /m 3cc, in subsystems 1, 2 and 3, respectively. The energy consumption rates were 2.76; 2.42 and 3.98 g/kW*m 3 cc, (FORMATAR )in subsystems 1, 2 and 3, respectively.
