- Abstract
Chainsaws and electric saws are intensively used for cutting trees by small farmers as well as by large reforestation companies. This study aims to characterize the technical criteria for the selection of chainsaws and electric saws commercialized in the Brazilian market. Data were gathered from technical catalogs published by manufacturing companies and assemblers of these machines in Brazil. We analyzed the following characteristics: brand, model, power, mass, motor, and cutting assembly. For the classification of chainsaws and electric saws in technical criteria, we adopted the classical literature that differentiate the machines as light, medium and heavy. We adopting the power classes according to the available models. Results identified 14 brands of chainsaws that produce 155 models with internal combustion engines (two-stroke). Results for electric saws indicate the existence of nine brands that offer 44 models with power supply by cables or batteries. In professional machines, power ranges from 2.30 to 5.20 kW. In machines for occasional use, power is usually less than 2.20 kW. The middle and heavy classes had lower mass/power ratios when compared to the light class. We found that the increase in power also increases the volumetric capacity of the fuel tank. As criteria for the selection of studied machines, we highlight the purpose of use, mass/power ratio, fuel tank volume and saber length.
