Abstract

RE S E A R C H HY D R AU L IC S Open Circuit Displacement Control in a 300 t Mining Excavator Hydraulic systems of large scale, as can be found in mining excavators, have typically been based on simplicity and durability. Typical architectures are open-centre hydraulic systems, which were designed with robustness and productivity in mind; however, they lack competiveness with other hydraulic systems in terms of energy efficiency. Displacement control has shown a promising potential especially in multi- actuator machines such as excavators. At the Technische Universität Dresden, an open-loop displacement control system was compared with today’s valve-controlled drive system in a mining excavator. A U T HOR S Roman Ivantysyn, M.
