Application of the Work Study to Balancing Hydraulic Component Assembly Lines

Abstract

This paper applies the methods of Work Study to a certain hydraulic component company. We apply the work measurement method to measure the work time of various stations of assembly lines, and to find out both the bottle neck stations and the superfluous capability stations effecting on the line assembly capability. Basing on the principle of ECRS (Eliminate, Combine, Rearrange, Simple) and the line balancing theory, this paper provides the line balancing schema, including the improvement of the existing equipment, the reallocation of the work content for relative stations, the adjustment of the equipment and workers of some stations, the reduction of machine working time of some stations and the change of assembly line layout etc. After being improved, the work time of the bottle neck and other processes are controlled near the Taking Time. Comparing with the former assembly line, the production capability of assembly line improved up 45.6% and workshop condition is also improved.
