Resumo: The objective of this research was to conduct an operational analysis of forest harvesting activities in a mechanized of the system cut to length in eucalypt plantations in south of Bahia, to determine the distribution of operation times, productivity, operational efficiency and mechanical availability of two models of harvester and two models of forwarder, evaluating these machines in three modules harvesting methodology through time and motion studies. Auxiliary activities corresponded to the lowest percentages within the operating times (mean 1.9% to 1.8% for harvester and forwarder), already operating activities were those that had the highest percentages. The first shift was presented the worst results of operations for the harvester (average 66.3%) and the third shift for the forwarder (55.5%). For the harvester module 1 showed the best result of productive times (average 70.36%). In relation to the forwarder, this same module showed the worst results with unproductive times (average of 22.17%). The availability and mechanical parameters were superior productivity for the forwarder (mean 82.31% and 51.33 m3/h, respectively), as indicators of degree of utilization and operational efficiency were higher in harvester (average 85.01% and 66.41%, respectively). Thus, for the forwarder, the parameters mechanical availability and productivity were higher, while for the harvester, they were the indicators of degree of utilization and operational efficiency

Foram determinadas a distribuição dos tempos operacionais, produtividade, eficiência operacional e disponibilidade mecânica de dois modelos de colhedor florestal (harvester) e dois modelos de trator florestal autocarregável (forwarder), em três módulos de colheita florestal através da metodologia de estudos de tempos e movimentos. As atividades auxiliares corresponderam aos menores percentuais dentro dos tempos operacionais (média de 1,9% para o harvester e 1,8% para o forwarder), já as atividades operacionais foram as que resultaram em maiores percentuais. O primeiro turno de trabalho foi o que apresentou o pior resultado operacional para o harvester (média de 66,3%) e o terceiro turno para o forwarder (55,5%). Para o harvester, o módulo 1 apresentou o melhor resultado de tempos produtivos (média de 70,36%). Em relação ao forwarder, este mesmo módulo apresentou os maiores tempos improdutivos (média de 22,17%). Os parâmetros de disponibilidade mecânica e produtividade foram superiores para o forwarder (média de 82,31% e 51,33 m3.h-1, respectivamente), enquanto o grau de utilização e eficiência operacional foram superiores no harvester (média de 85,01% e 66,41%, respectivamente). Dessa forma, conclui-se que que para o forwarder, os parâmetros disponibilidade mecânica e produtividade foram superiores, enquanto que para o harvester, foram os indicadores de grau de utilização e eficiência operacional.Revista Árvore2018-01-08T13:22:23Z2018-01-08T13:22:23Z2017-08-24info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1806-9088http://dx.doi.org/10.1590/1806-90882017000300001http://www.locus.ufv.br/handle/123456789/16147engv. 41, n. 3, e410301, Ago. 2017Fiedler, Nilton CesarCarmo, Flávio Cipriano de Assis doMinette, Luciano JoséSouza, Amaury Paulo deinfo:eu-repo/semantics/openAccessreponame:LOCUS Repositório Institucional da UFVinstname:Universidade Federal de Viçosa (UFV)instacron:UFV2024-07-12T06:20:42Zoai:locus.ufv.br:123456789/16147Repositório InstitucionalPUBhttps://www.locus.ufv.br/oai/requestfabiojreis@ufv.bropendoar:21452024-07-12T06:20:42LOCUS Repositório Institucional da UFV - Universidade Federal de Viçosa (UFV)false
