AI Technical Summary

Technical Problem

The existing hydraulic systems of AGV/IGV trolleys have problems such as high energy consumption, complex troubleshooting, and large amount of construction work. Traditional centralized oil supply hydraulic systems are inefficient and cannot meet the energy-saving requirements of modern port equipment.

Method used

The system employs an electro-hydraulic power unit transmission and control system, including a steering electro-hydraulic servo power unit and a parking brake electro-hydraulic power unit. Combined with an electro-hydraulic system controller, it achieves modular and distributed control via CAN, Profinet, or Profibus bus, reducing hydraulic lines and control cables, and adopting closed-loop volume control to improve efficiency.

Benefits of technology

It enables low-energy operation of AGV/IGV vehicles, simplifies wiring and troubleshooting, improves the convenience of equipment maintenance and component replacement, and reduces the risk of hydraulic oil leakage and contamination.
