A Digital Control System for Hydraulic Excavator Fixtures

Abstract

533The cutting tool trajectory of a hydraulic excavator during working with traditional machine results from experience and intuition of an operator. To allow the excavator for an automatic execution of planned trajectories, the machine should be provided with control system of fixtures motion. Such a digital control system for single bucket excavator, which has been built in the Kielce Branch of the Institute of Fundamental Technological Research of Polish Academy of Sciences, is presented in this paper.
