Abstract
The hydraulic excavator is versatile machinery, with the development of society favored by the majority of the construction unit. Production and manufacturing of hydraulic excavators are also increasingly flourished.
This paper introduces the overall design and related calculations of the ZE230E excavator. Firstly, through the early information-gathering and market research, as well as the excavator's job profile and performance requirements, the design scheme of excavator is determined; according to the design, the overall parameters and power-plant of the excavator are calculated and determined. Secondly, hydraulic excavator hydraulic system, working device, running gear, slewing mechanism, as well as turntable are preliminary selected and designed based on the overall parameters and power-plant; excavator digging resistance, digging force, power, productivity, and turntable balance were also calculated. Finally, the whole stability of the excavator is checked. In this project, parts and the whole diagram are drew by using the CAD software.
