Manutenção Preventiva Como Determinante Para Redução De Custos De Manutenção De Um Feller Buncher

Abstract

RESUMO ABSTRACTThis work evaluated the mechanical maintenance activity of a feller buncher using World Class Maintenance (WCM), which uses preventive maintenance as a premise, aiming at reducing production costs and making better use of available resources. The study was carried out in Pinus taeda and Eucalyptus grandis stands of a forest company located in Paraná State, Brazil. The analysis contemplated three subsequent periods of six months, being: implantation, ripening, and stabilization of the WCM model. The evaluation was performed through the determination of mechanical availability, hydraulic oil consumption, and maintenance costs. The results showed that there was an increase in mechanical equipment availability of 1.75%. For the consumption of hydraulic oil, after the implementation period, there was a 63% reduction, reflecting the preventive maintenance carried out during the activities. The maintenance cost in the WCM model showed a 14.4% reduction, due to the investment of infrastructure and training of mechanics and operators. The WCM model showed applicability in the maintenance of forest cutting equipment, with potential for improving operational safety, productive capacity, and increasing their useful life. PALAVRAS-CHAVE:Corte florestal, Mecanização, World Class Maintenance.

HARVESTER PRODUCTIVITY AND COSTS IN CLEAR CUTTING Pinus taeda STANDS UNDER DIFFERENT MANAGEMENT REGIMES

“…Delays were caused by the time consumed by fuel supply, followed by calibration, due to the need of the support vehicle to attend more than one farm, as well as the lack of knowledge by the operator to perform the calibration, which needed supervision support. Thus, a need for logistic planning of the convoy vehicle and recycling operator training to calibrate the machine stands out (LOPES et al, 2008;DINIZ et al, 2017).…”

Otimização De Processos De Manutenção Por Meio Da Utilização De Ferramentas Tecnológicas

“…As interferências semanais realizadas na operação e o almoxarifado de campo permitiam um maior fluxo de atividade, mesmo quando há a necessidade de manutenção corretiva, o tempo de serviço é menor, com um retorno consequente da máquina para a atividade em pouco tempo (DINIZ et al, 2017).…”

Influência Das Interrupções Sobre O Grau De Utilização De Picadores Florestais

“…Definida como o tempo em que a máquina está disponível para realizar o trabalho, desconsiderando os tempos em manutenção, a disponibilidade mecânica foi obtida pela equação 1 (LOPES et al, 2016;GUEDES et al, 2017;DINIZ et al, 2017).…”
