Optimum design of containers for manual material handling tasks.
The container in manual material handling represents the point of interface between the worker and his task as well as with the surrounding environment. It is at this point that many of the well known handling hazards occur which manifest themselves in stresses and strains that are transmitted to the body via the musculo-skeletal system. If a substantial number of handling hazards is to be controlled or eliminated at the source, containers designed in accordance with principles of biomechanics and related recommendations provide a logical starting point. The container characteristics to be considered in the design process are weight (and its distribution), shape, stiffness, and availability of coupling devices. This paper presents several examples which outline and detail a number of problems associated with the design of containers involved in manual tasks. Application of basic mechanics, coupled with the use of optimization techniques, is presented as the approach for dealing with the hazards and problems of containers.
