Assessing Ergonomic Risks in Worker Postures: The Case of Belt Conveyor Assembly

In the study, the working conditions that challenged the employees during the assembly process in a factory where a belt conveyor was manufactured were analyzed using the REBA method. As a result of the evaluations, these challenging working postures were examined in seven stages. It was observed that the employees performed the assembly process primarily in squatting and heavily leaning postures. While the REBA score was recorded as 2 in the six stages related to assembling the carrier rollers onto the chassis of the conveyor belt, the highest REBA score, 13, was found in the seventh stage, which involved assembling the electric motor. It was recommended that the assembly operations be conducted on a movable platform with adjustable length and height, and that an additional platform capable of horizontal movement be used during the assembly of the electric motor. This approach would improve the risk protect for workers and help safeguard their health.
