Analysis of the Working Time of Assembly Railway Pantograph

Abstract

Every single company seeks to ensure good quality products in parallel to the most effective production processes in its manufacturing plant. To achieve those goals, the organization of the workplace is very important. It shall be maximally adapted to the production of a given product, thereby increasing employee productivity which provides an added value through saved time. Thanks to the study of work processes time, it is possible to determine the workload of individual activities and its continuity. It could be realized by using the basic methods of working time analysis, e.g., time study, activity study, comparisons and estimations, and methods of time measurement (MTM). The objective of the work was to analyse the assembly work time of selected subassemblies of the half-asymmetric railway pantograph and the proposal to reorganize the workplace and production technology. Every activity during subassemblies production steps were recorded on video. Then, all elementary movements were described through Methods Time Measurement (MTM) and the reorganization of the workplace was proposed. Knowing the course of the process steps of each subassembly and by analysing all obtained results, the organization of the workplace could be modified to minimize the process time as much as possible.
