Abstract

This paper presents results of an experimental study conducted with an electrified small sized excavator, whose boom swing function is equipped with digital hydraulic multi-pressure actuator. Highlighted and discussed are the performance, energy efficiency and controllability of the function in varying inertia loads. In addition, component-specific energy losses are analysed. This data is compared with the results gained with the excavator’s original control arrangement, a load-sensing system based on pressure adjustment valve. Results manifest high energy saving potential of the multi-pressure system in mobile machinery.
