Review for Development of Hydraulic Excavator Attachment

The hydraulic excavators are widely used in construction, mining, excavation, and forestry applications. Its diversity and convenient operability make it popular. The performance of hydraulic excavator is depending on its performance of the backhoe front attachment. This paper focuses on the research work of excavator attachment, which mainly includes those aspects, such as the kinematic analysis, dynamic analysis, structural analysis, trajectory planning and control, fatigue life analysis and structural optimization design. and the development trends of excavator attachment，in the near future，are forecasted． Key words: Excavator; Attachment; Development
