The training focuses on the technical architecture and service standards of SDLG electric products, and systematically explains mainstream electric models such as loader L958HEV, E6225HEV, E655HEV, etc., deeply interpreting the design logic and operation key of high and low voltage electrical systems. In response to the weak knowledge of European service personnel in hydraulic systems, the course specifically sets up reinforcement learning modules, using models such as the Zhongdao E6225H and Xiaodao E636H as carriers, to break down the complex principles of mechatronics and hydraulic integration into clear and easy to master practical guidance, helping students build a complete and solid product knowledge system. In the practical training session, students engage in immersive learning and case studies on the maintenance process, fault diagnosis, and troubleshooting strategies of the main aircraft models. Through on-site equipment demonstrations, hands-on teaching, and simulated troubleshooting training, we help students bridge the transition path from theoretical understanding to practical operation. The training also includes real-time Q&A and skill assessment sessions to ensure that each participant can proficiently master key technical points and effectively enhance their service response capabilities in the complex working conditions of the European market. This training is not only a systematic output of technical skills, but also an important practice for SDLG excavator to deeply cultivate the European local market and jointly build a sustainable service ecosystem with partners.
