XCMG European Research Center GmbH
was founded in April 2013 and is the first Research & Development Center of the XCMG Group outside of China. In Krefeld, we optimize and develop new transmission systems of XCMG’s construction machines in close cooperation with our partners in China. The focus rests on hydraulic systems, which efficiently transform the power of diesel engines into strong and highly controllable working motions of the machine. Based on the analysis of the machine’s operational behavior alternative solutions are developed, put into prototypes and tested.
"Key to success"
In July 2019, the former general managers Dr. Oliver-Carlos Göhler and Dr. Hui Sun officially handed over the operative business to their successors, Mr. Harald Riedinger and Mr. Chengyu Zhang.
Mr. Riedinger is an exceptionally experienced Expert of mobile machine industry and successful leader of multinational and –functional teams. Mr. Zhang is an accomplished innovation manager who has been on board since the founding of ERC and returns as general manager, a position he already held together with Dr. Göhler during a previous stint from 2013 to 2016.
Together, Riedinger and Zhang will continue the successful development of XCMG’s first international Research Center and keep promoting first-class R&D for the mobile machines Industry from our site in Krefeld.
Hydraulic Pressure Supply
"The key place is on the field."
This famous saying also applies to the development of hydraulic components and systems. Ultimately, it depends on the functionality of the entire machine. Still a "training ground" is helpful. In four sound and vibration insulated test units, experimental setups are installed for testing of hydraulic components and systems at the XCMG European Research Center . To carry out the tests an advanced hydraulic pressure supply has recently been put into operation. Its main part is an centralized hydraulic power unit which at a maximum pressure of 450 kW of hydraulic power at pressures up to 420 bar and is capable of directing the power independently towards individual test benches. This is achieved by means of a state-of-the-art control system which determines the required power demand, starts up the required pump units and connects them to the consumers via a valve matrix. Additionally, the system is capable of recovering energy in to enable an economic operation. The system is based on a concept created by XCMG ERC which was further developed and built in co-operation with Hydrodynamics B.V. and Ingenieurgemeinschaft IgH.
With the latest enlargement of our machinery we are able to significantly shorten the development cycle of new components, starting from project idea to verification on the test benches and in the machine. Recently, an ultra-modern 5-axis milling center of the company Hermle was set in to operation. After successfully starting, and given the very good results with different complex manifolds, our prototype expert Michael Nilges is full of praise for the machine and its potentials.
The short lines of communication between design and production regarding modifications and adjustments for an optimal functioning and short production times are beneficial as well. Thus, were are able to ensure fast and efficient development processes.
