Excavators’ Cabins Ergonomic Design Influential Factors Modelling: Preliminary Study

Abstract

Excavator operators encounter demanding work environments with very high risks for discomfort, musculoskeletal disorders, and workplace accidents. In line with that, this study examines the relationship between ergonomic design influential factors using the structural model of excavator cabins design factors, using a sample of 32 excavator operators. Descriptive statistics were performed to describe the operator's age, height, weight, working experience, and excavator's lifespan. After that, the structural equations model was developed to describe the impact of latent variables related to ergonomic design of the cabin. This model was constructed by using 17 questions, which were categorized into 5 groups based on ergonomic design characteristics such as seat, armrests, commands, cabin, and working conditions. The findings indicate that the model exhibits favourable reliability and validity coefficients, a substantial effect size, and a satisfactory model fit. Further research is needed to increase the sample size, despite the preliminary nature of the current research and its satisfactory results.
