Resumo: | http://dx.doi.org/10.5902/1980509813335Excavators are commonly used in forest harvesting in Brazil as an option to typical forestry harvesters, mainly because of their lower cost and also because some models are being manufactured locally, which means more units sold, facilitating dealer’s support and purchase of parts. Problems with excavators are related to high cost of tracks maintenance and difficulties to operate on steep ground terrain, when compared with wheeled harvesters. This study compared excavators, used as forestry harvesters, with wheeled harvesters to fall Eucalyptus tree plantations located on flat terrain. The productivities of both machines were quite similar, but the higher cost per effective hour of wheeled harvesters, concerned the models utilized in this study, favored the use of excavators, as base machines, to fall trees in a clear-cut system on flat terrain. |

Sua utilização baseia-se principalmente no custo menor de aquisição e a existência de modelos fabricados no país, facilitando a assistência técnica e a compra de peças e manutenção. Argumentos contrários referem-se ao custo elevado de manutenção das esteiras e uma maior restrição à operação em terrenos acidentados, em comparação com máquinas de pneus. O objetivo deste trabalho foi comparar, quanto a aspectos técnicos e econômicos, a utilização, na operação de corte de árvores em terreno plano, de modelos de harvesters de pneus com escavadoras de esteiras adaptadas para uso florestal. O maior custo hora dos modelos de harvesters de pneus, utilizados nas condições deste estudo, favoreceu a indicação do emprego de harvesters com máquina base de esteiras na operação de corte raso de árvores em povoamentos localizados em terrenos planos, com os dois modelos de máquinas apresentando produtividades muito próximas em condições de povoamentos florestais teoricamente similares.Universidade Federal de Santa Maria2014-03-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1333510.5902/1980509813335Ciência Florestal; Vol. 24 No. 1 (2014); 185-191Ciência Florestal; v. 24 n. 1 (2014); 185-1911980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/13335/pdf_1Seixas, FernandoBatista, João Luís Ferreirainfo:eu-repo/semantics/openAccess2017-04-13T18:15:24Zoai:ojs.pkp.sfu.ca:article/13335Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-13T18:15:24Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false |
