Electro-hydraulic control systems for mobile machinery with low energy consumption

摘要：

The paper deals with the development of electrohydraulic Load-Sensing Systems for construction machines which have the potential to run in a fully automated excavator. They combine the robustness and effective pricing of hydraulic-mechanical LoadSensing with the high efficiency and good controllability of electro-hydraulic control systems. The new systems reduce the energy consumption of excavators in typical load cycles by about 11％. The enlargement to dual circuit systems increases the savings. The electronic control enables the possibility for closed loop controls to reach a high accuracy when running automated trajectories.
