Excerpt

Most excavator drivetrain architectures continue to be based on the interaction between the hydraulics and engine. A comprehensive analysis of the loss mechanisms provides new ways to optimise the energy efficiency and performance. Within the scope of a publically fundend project, the IFAS at the RWTH Aachen University has spent the last three years developing a hydraulic hybrid architecture for excavators. The system has been implemented in an 18 t wheeled excavator and recently validated in field tests. …
