Wheel loaders are utilized not only on construction sites, but also for general purposes, such as manufacturing and transportation. Therefore, during the basic design stage of this type of working device equipment, the designer should consider specifications as well as working performance. In this research, a characteristic analysis program was developed for use in the basic design stage of construction equipment using multibody dynamics analysis. In addition, through the optimization of its links, improvements to the lifting capability of a Z-bar-linkage-type wheel loader were suggested. Using the developed program and process, it is possible to reduce the time required for the basic design of the working device.
