Resumo: The objective of this study was to evaluate the performance and determine the costs of two cable yarder systems in the extraction of eucalyptus wood in mountainous regions. The technical analysis was based on the study of times and motions of the operating cycle and productivity of two extraction systems: System 1 (tractor Massey Ferguson 297 and winch Penzsaur K301-T) and System 2 (excavator Caterpillar 320L and winch Koller), operating in plantations aged seven years old and of second rotation. Average productivity in logging was 13.63 m3 h-1 for System 1 and 14.70 m3 h-1 for System 2 for a distance of 150 m on average, operating efficiency of 46% and 51% and mechanical availability of 91% and 59%, respectively. The increased extraction distance resulted in increased time to perform the activities of the operating cycle and reduced productivity. System 2 was more productive, but showed higher production costs.

A análise técnica baseou-se em estudo de tempos e movimentos do ciclo operacional e produtividade de dois sistemas de extração: Sistema 1 (trator Massey Ferguson 297 e guincho Penzsaur K301-T) e Sistema 2 (escavadora Caterpillar 320L e guincho Koller), operando em plantios com idade de sete anos e de segunda rotação. A produtividade média na extração de madeira foi de 13,63 m3 h-1 para o Sistema 1 e 14,70 m3 h-1 para o Sistema 2, para distância média de 150 m, eficiência operacional de 46% e 51% e disponibilidade mecânica de 91% e 59%, respectivamente. O aumento da distância de extração implicou em aumento no tempo para realizar as atividades do ciclo operacional e em redução da produtividade. O Sistema 2 mostrou-se mais produtivo, porém, apresentou maior custo de produção.Universidade Federal de Santa Maria2017-06-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/2773710.5902/1980509827737Ciência Florestal; Vol. 27 No. 2 (2017); 571-580Ciência Florestal; v. 27 n. 2 (2017); 571-5801980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/27737/pdf_1Copyright (c) 2017 Ciência Florestalinfo:eu-repo/semantics/openAccessGuedes, Ilvânio Luizdo Amaral, Edvaldes JoséLeite, Elton Da SilvaFernandes, Haroldo CarlosSant'Anna, Cleverson de Mello2017-07-08T02:45:32Zoai:ojs.pkp.sfu.ca:article/27737Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-07-08T02:45:32Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
