Features

High-Power Electric Drive Excavation System

The 55kW 380V high-voltage electric drive system delivers stable and continuous high-torque output, ensuring reliable performance in heavy-duty excavation, mining, and earthmoving operations. Compared with diesel-powered systems, it reduces energy consumption by up to 70% while maintaining strong productivity under continuous load conditions.

Industrial-Grade Hydraulic Transmission System

Equipped with Zhongchuan main pump, control valve, travel motor, and swing motor system, the hydraulic architecture ensures stable pressure output and precise operation control. The integrated system is designed for heavy-load excavation environments, delivering consistent performance in mining and large-scale construction applications.

Zero-Emission Low-Noise Operating Platform

The electric power system enables zero emissions and significantly reduced operational noise, making the machine suitable for environmentally restricted zones, underground construction, and urban infrastructure projects where emission control is required.

Low Maintenance Electric Powertrain System

The electric drive system eliminates traditional engine maintenance requirements. Key components such as the motor only require lubrication every 2000 hours, significantly reducing downtime and long-term maintenance costs while improving overall equipment availability.

Multi-Scenario Working Capability System

Through quick attachment replacement, the machine can adapt to multiple working conditions including excavation, loading, and material handling, providing high versatility for mining, construction, and infrastructure projects.

High-Safety Electrical Control Architecture

The electric control system is equipped with 4-pole leakage protection, centralized circuit transfer station, and CMC-MX soft-start technology, ensuring safe power distribution, reduced starting current, and improved system reliability under complex jobsite conditions.

Operator Comfort and High-Stability Cabin System

The ROPS-certified cabin features panoramic visibility, air-conditioning, ergonomic controls, and reinforced steel structure, ensuring operator safety and reduced fatigue during long-duration heavy-duty operations.
