Intelligent Hydraulic Control System
LiuGong's proprietary load-sensing hydraulic system continuously measures work demand and adjusts pump displacement in real time. This eliminates wasted hydraulic flow, reducing fuel consumption by 12–18% compared to conventional open-center systems. The system also provides smoother control response for precision excavation tasks including grade finishing and trench profiling.
Pilot pressure: 35 bar. Main system pressure: up to 350 bar (35 MPa). Variable displacement axial piston pump with electronic flow compensation.
IoT-Connected Telematics Platform
Every LiuGong machine can be equipped with the proprietary telematics module, providing fleet managers with real-time data on GPS location, fuel consumption rate (L/h), engine operating hours, hydraulic system temperature, and maintenance schedule alerts. The cloud-based platform is accessible from any web browser or mobile device.
Remote diagnostics enable service technicians to read fault codes and recommend corrective action without dispatching to the job site — reducing diagnostic time from hours to minutes.
Hybrid Electric Power Systems
LiuGong hybrid excavators combine a downsized diesel engine with an electric motor-generator and supercapacitor energy storage. The swing motor regenerates braking energy during house rotation, storing it for reuse during the next dig cycle. Total fuel savings: 25–30% in typical dig-load-swing-dump operations.
All hybrid models meet EU Stage V and EPA Tier 4 Final emission standards without the need for diesel exhaust fluid (DEF/AdBlue) — simplifying operating logistics in remote regions.
