Abstract

This project has been conducted in PHN Industry Sdn.Bhd such an automotive industry located at Shah Alam. This final year project is focusing to produce an ergonomic trolley based on anthropometry data of workers at PHN company. The data of the problems encountered through a questionnaire survey among 14 workers at Receiving Area only, since it has the highest number of ergonomic risk factor. According to the observation, interview and distributed questionnaire, the main problem is the existing trolley design in current factory, seems not suitable and giving many problems on musculoskeletal disorder of the workers especially back pain. Therefore, the aim of this project is redesign the material handling system by using ergonomic approaches to reduce back pain risk. The Tekscan software will be used for evaluating hand pressure distribution force. Tekscan test has been done on the existing and the alternatives trolley. The result obtained is used as a benchmark for the concept of trolley to be redesign. The selection of concept design is then finalized by using Quality Function Deployment (QFD); House of Quality (HOQ), Screening and Scoring method. The final 3D modelling design of the trolley was drawn by using SolidWork software. The Rapid Upper Limb Assessment (RULA) was applied to analyse the posture of workers on the existing and the alternative trolley also to the redesign trolley to be proposed at PHN. Based on the RULA analysis, the redesigned trolley has improved the posture of the workers. Hence, this study concludes that considering ergonomic features for the redesigned trolley contributed to safe body posture.
