AVALIAÇÃO DO DESGALHADOR FLORESTAL DE DISCOS EM FUNÇÃO DO TEMPO DE ESTOCAGEM DA MADEIRA EM CAMPO

With the innovations of mechanized harvesting in Brazil, become necessary studies to obtain real data on the new machines that are emerging in the market. The study aimed to the technical evaluation and cost a forest delimber on trees with different times storage in the field, and verify possible correlations among wood moisture, productivity and cost of production. For the technical analysis was conducted a study of time and motion by timing method of continuous time and for the cost analysis, we calculated operating costs through the method proposed by ASABE. Approximately 40 days in the field trees reached the equilibrium moisture content, the moisture has demonstrated no correlation of content with the performance of the machine, which was on average 643.34 m3/h, and not with the cost of production, and, the operating cost of R$ 180.04 / hour, and the production cost average R$ 0.28 / m3.
