AVALIAÇÃO DE CARGA FÍSICA DOS OPERADORES DE MÁQUINAS AGRÍCOLAS NO LITORAL LESTE DO CEARÁ
Abstract
Tractor use is increasingly indispensable in the production chain of most economic interest. The rising tractors use reflects not only the productivity increase but also the risk to which agricultural machinery operators are subject. Among several risks, can be mentioned the physical load, activities considered heavy, that can cause dizziness, nausea and even fainting, increasing the accidents risk. One way to evaluating this physical load is through the heart rate analysis. From this information, the aim of this work was to evaluate the physical workload in different activities with tractor, verifying if these activities are unhealthy for agricultural machine operator. The work was conducted on the eastern coast of Ceará. The physical work load was performed by means of operators’ heart rate survey activities of harrowing, spraying and coconut harvesting and transport. Spraying and harvesting activities were classified as light and harrowing was classified as moderately heavy. Harvest activity was the one that demanded less effort from operators. None of the activities were unhealthy and did not require rest time, however harrowing activity was 456 Macedo et al./Avaliação de carga.../v34n4p455-461 (2019) considered moderately heavy by study conditions thus, there is a need for a greater attention with this kind of activity.
