Abstract

Machine-based sugar-cane harvest has been on the increase and its use requires strict control on equipments, especially, harvesting machines. Blades are replaced or inverted according to wear and tear, requiring specialized labor and loss of machine time. Current paper discusses three methods for blade exchange or inversion so that availability of the machine would be increased for better production through the Overall Equipment Effectiveness performance and Rapid Tool Replacement. Results showed that Rapid Tool Replacement increased the availability of the equipments for 347 minutes, with production increase of 115.9 tons/day. Time samples were collected and analyzed in three shifts with each tested system. Aspects related to the adaptation of tools used, effort and fatigue, logistics of spare parts and tools were assessed for the improvement of the machine operator. [ABSTRACT FROM AUTHOR]

A colheita de cana é considerada como uma das operações mais importantes, pois deve atender à demanda de matéria-prima requerida pela Usina com qualidade e custo competitivo. O objetivo deste trabalho foi analisar, de modo sistêmico, a influência das variáveis no desempenho operacional e econômico do processo de colheita mecanizada da cana-de-açúcar para o dimensionamento das máquinas. Para tanto, foi desenvolvido um modelo, denominado de ColheCana, em planilha eletrônica e em linguagem de programação. Os resultados evidenciaram que a eficiência de campo e o valor inicial das colhedoras são variáveis de grande impacto no custo e que existe uma área máxima a que um equipamento pode atender para a qual o custo é mínimo. Sugarcane has a significant role on Brazilian agribusiness economy. The harvesting cane is considered as one of the most important operations of the process for it has to attend the raw material demanded by the sugar mill in quality and a competitive cost. The objective of this work it is it of analyzing, of systemic way, the variables influence on economical and operational performance in sugarcane mechanized harvesting process for sizing of machines. For this purpose a model called ColheCana, was developed in a spreadsheet and in a programming language. The results showed that the field efficiency and harvester´s initial value are variables of great impact in the cost and that there is a maximum area that one equipment can attend and for this area the cost is minimum.
