Abstract

apresentar perímetro linear para a distribuição das pilhas serviço corredor de árvores, rendimento operacional Abstract This study aims to analyze the operational performance of the grapple saw in Eucalyptus grandis Hill stands with and without the influence of ecological corridors, as well as to verify the feasibility of building a service branch for the grapple saw parallel to existing native vegetation. In the technical analysis, the operational efficiency, mechanical availability, and productivity of the machine were determined. In the financial viability analysis, the costs of the grapple saw in wood processing were determined by application in two projects (with and without the presence of an ecological corridor) and with the construction of a parallel service branch next to the native vegetation. The grapple saw showed high mechanical availability and operational efficiency in the two evaluated projects. The main factors that influence the duration of its operational cycle and productivity were the average volume per tree and average height of the wooden cuttings. The effective productivity of this machine was higher in the PG1 project (devoid of ecological corridors) because it has a larger linear perimeter for the distribution of wooden piles and consequently, their lower heights. The construction of a service branch parallel to the ecological corridor proved

有和没有生态廊道的桉树林木追踪作业:对产量和成本的影响

摘要本研究旨在分析有无生态廊道影响的大桉树山林中钩锯的运行性能，并验证与现有原生植被平行建立钩锯服务分支的可行性。在技术分析中，确定了机器的操作效率、机械可用性和生产率。在财务可行性分析中，木材加工中钩锯的成本是通过在两个项目中的应用(有和没有生态走廊)以及在原生植被旁边建造平行的服务分支来确定的。在两个评估项目中，抓钩锯显示出较高的机械可用性和操作效率。影响其作业周期和生产率的主要因素是每棵树的平均体积和木插枝的平均高度。在PG1项目(没有生态走廊)中，这台机器的有效生产率更高，因为它有更大的线性周长来分配木桩，因此，它们的高度更低。与生态廊道平行的服务分支的建设证明了这一点
