Abstract

ABSTRACT This study aimed to perform a machine operational analyses used on the eucalyptus mechanized harvest, in four different regions of the Espirito Santo and Bahia states. The activities were performed by own and outsourced labor, the regions had a similar climate condition, relieve and similar machine, the harvest forest tractor. The mechanical disponibility, operational efficiency, machine production was analyzed during a 12 months period in the field and by the operational output from the database from 60 own machines and 60 outsourced machines in each one from de four regions (120 machines). Based on the results, it was observed that in the own module and the outsourced, variables were the mechanical disponibility operational efficiency and technical disponibility did not have different during the study period, among the regions. The executed work with own machines had a higher production when compared to the outsourced, with exception of the regions A and C. The total volume produced per year by the cut forest with the own machines were higher than 1.234.310 m3 to the total volume cut with outsourced machines, showing a higher operational efficiency when the harvest was made with an own model.

Highlights

Until the late 60s, the forest harvest in Brazil was almost exclusively done in native forest, and at the most part of the times in a predatory form

Summary

Introduction

Until the late 60s, the forest harvest in Brazil was almost exclusively done in native forest, and at the most part of the times in a predatory form. An expansion of the sector happened, allowing the sector recognition by the society for its contribution to the economic, social and environmental on the country. Trough this fact, Schuchovski (2003) said that the planted forest, the Eucalyptus genus, are essential feedstock, integrating different productive chain, as an example: cellulose and paper; Steel industry; energy; Panels; Furniture and solid wood, making a great contribution to work creation and income. According to Machado & Lopes (2000) and Silva et al (2014), the harvest and transport activity has a great economic importance to the forest sector, and it should be designed to reduce that costs, that can represent more than 50% of the total cost of the wood present in the industry. On that way, is very important to verify the best operational system, outsourced or own, that would result in a lower cost by produced volume, considering the financial resources available to those activities (Carmo et al, 2015)
