The result of process of transfer of such items, humans require a breakthrough to human work in moving goods become more easily. One of the role of technology development is the creation of a means of transportation. Any technology must have a shortage of being essentially will be developed again to achieve a function that most excellent in human help with the work. In this study, the focus is doing the improvement of braking system from results of research on the system level design and deatil five wheels hand truck. Of research results, obtained a draft of the prototype that complements the lack on previous research so wor tools become better at helping human work |
