Abstract
This study aims to analyze the pivot type trailer operation with an ergonomic approach and the necessary interventions required to minimize work risks. Data collection was carried out using questionnaires and video recordings of the operators when the tractors as well as trailers were being operated at various conditions such as track, load, speed, straight motion or turn. Based on the Range of Motion (ROM) analysis, it was discovered that while operating this pivot type trailer, the upper body segments, such as neck, shoulders, elbows and back of the operator, comfortably controlled the tractor. Meanwhile, in the lower body segments, such as the thighs and knees, the operator generally felt discomfort. Furthermore, the analysis of the operator's subjectivity perception showed that discomfort was felt at several segments of the upper and lower body, such as the hands and knees. Therefore, several ergonomic interventions are required to increase the comfort of operating this pivot type trailer.
