Excavators for Municipal Construction

Industry-renowned Weichai high-performance engine:
Equipped with a Weichai WP4.6N four-cylinder engine, delivering a powerful 129kW of power, its performance rivals that of mainstream six-cylinder engines in the industry, fully meeting the 20-ton operating needs of customers. Daily operations are streamlined and hassle-free. Optimized post-processing regeneration logic extends regeneration intervals, saves fuel, and ensures maximum operational efficiency.

Powerful Operating Performance:
The front body combination of a 5.6m boom and a 2.9m arm provides a wide operating radius and enhanced maneuverability. The heavy-duty reinforced design of the boom and arm, with optimized key structural features and increased steel plate thickness, fully handles demanding operating conditions and ensures quality and durability. The large 0.92m³ bucket unleashes full productivity, featuring an optimized bucket shape for even better operating performance.

High-Performance Hydraulic System:
The durable, negative-control hydraulic system, fully tuned and proven through thousands of hours of operation, delivers exceptionally coordinated operation.
The custom-made, imported hydraulic main valve features a large-diameter design, delivering superior hydraulic performance and fully meeting the demands of various operating conditions.
The newly imported hydraulic main pump boasts an 8% increase in system flow compared to the previous generation, providing more robust hydraulic system flow. Combined with the large-displacement main control valve, this pump delivers more coordinated operation.

Excellent Fuel Economy:
The machine automatically detects operating load conditions and adjusts engine performance under light load conditions, perfectly matching power output to actual operating conditions and significantly reducing fuel consumption.
Multiple selectable operating modes (P+/P/S/E) allow the operator to proactively adjust engine output based on operating conditions, resulting in significant fuel savings.
