Effective operational capacity of brushcutter with different cutting tools
Parcianello, Carolina Fogliarini; Brandelero, Catize; Werner, Valmir; Bertollo, Gilvan Moisés; Silva, Lucas Caye da; Rodrigues, Luigi de AlmeidaBrushcutters use different cutting tools with variations in operating capacity. Thus, the present study evaluate the effective operational capacity of a brushcutter equipped with different cutting tools in different areas of plant cover. It was subdivided into three experiments with 44 replicates of 4m2 each. The first was carried out in an area with plants cover with wheat and ryegrass, with blades of triple a...
Hand-arm vibration while operating a side brush cutter with three cutting imple...
Cella, Mateus Cassol; Werner, Valmir; Brandelero, Catize; Bertollo, Gilvan Moisés; Silva, Edvaldo Faour Coutinho da; Schlosser, José FernandoThe use of side brushcutters exposes users to vibration and noise, which can cause damage to the operator, as they act as a stressor agent. Excessive vibration is responsible for countless disorders, including Raynaud’s syndrome. This study aimed to assess the effect of the vibrations of a side brush cutter on the human body. A side brush cutter was used with three cutting implements (double blade, triple blade...
Conservation conditions of chainsaws and electric chainsaws and safety of the f...
Benetti, Bruno Bortoluzzi; Brandelero, Catize; Werner, Valmir; Ottonelli, Jaqueline; Silva, Rodrigo Pinto da; Fortes, Fabiano de OliveiraThe increasing use of chainsaws in rural areas has demanded the health of rural producers who operate these machines. Thus, the objective of this work was to evaluate the conservation conditions of chainsaws with a 2-stroke Otto Cycle engine and check if they meet NR12 Annex V, as well as confirm whether users meet NR31 in terms of training for use. With the aid of a questionnaire and visits to farms, 103 chain...
