Abstract:
Aimed at the present problems that the theories for the design of economy excavators are lacking, and the economy excavators on market are in poor abilities and quality, the methods for conceptual design and main parameters of economy excavators are presented. The special construction and the high performance working range are described. For the new economy excavator, WYL50, is developed recently by three ways, including design, selection of parts and components, and manufacture are considered to cut down its cost and improve its performances and qualities. The performances of WYL50 are tested, and the results show that the excavator with reasonable parameters and perfect performance can satisfies all requirements of economy excavators. Compared with universal excavators, the manufacture cost is reduced 60 percent to 70 percent. The methods presented in this paper are reasonable and instructive to the design and manufacture of economy excavators. 1 tab, 6 figs, 8 refs.
