Abstract

This project is a preliminary study that investigates the space requirements for manual material handling (MMH) workstation design.MMH is the activity of transferring material manually from one location to another,which is widely applied in manufacturing companies.If workstation is not designed correctly,there is a higher risk for workers to experience musculoskeletal disorders (MSDs) when performing repetitive task for long hours.In some countries,guidelines for designing workstation has already been established.However,there is no evidence in Malaysian context that the same guidelines have been established for Malaysian populations.Therefore,a study that may contribute to that guidelines is needed.An MMH experiment has been conducted to see the patterns of hip and hand wrists motions from top view,in order to map the space requirement for MMH workstation design.A total of 15 male volunteers participated in this experiment.In this study,the constant parameters were the heights of the origin and destination stations and the weight of box to be transferred.Meanwhile,the manipulative parameter was the lateral transfer distance which was set to 0.5m, 0.75m,1.0m,and 1.25m.The motion capture system used was X-Sens set. Meanwhile the software involved for data analysis were MVN Studio,Cinema 4D,Microsoft Excel 2013, and Solidworks 2013.The results from this study show that the patterns of participants’ hip and hand wrists motions are most static and curve in shape for shortest lateral distance,when mapped from top view.The pattern slightly changes into a more stretched-curve shape as the lateral distance increases.From the mapping of the hip and hand wrists motions,it was observed that smaller space requirement causes participants to possess more twisting and less bending postures,while bigger space requirement results in more bending and less twisting postures during MMH.
