FEATURES
Cummins X12 Engine Complies with Tier 4 Emission Standards
The Cummins X12 delivers robust power, convenient maintenance, long-lasting durability, extended maintenance intervals, higher fuel efficiency, and effective cost savings for customer operations. Utilizing low-sulfur fuel and employing DOC+DPF+SCR post-treatment technology for Tier 4 emission control, the engine eliminates EGR, preventing power losses.
Equipped with a Rexroth high-capacity hydraulic pump
Featuring an original imported Rexroth high-capacity hydraulic pump with optimized main pump structure and integrated EPIC system, the system improves operational efficiency while achieving fuel savings.
Proven HCE Main Control Valve and Dual Rotary Motors
The main control valve includes a one-key boost function, providing instantaneous boost of 330(360) bar during heavy load for greater digging force, suitable for various earthworking conditions.
Heavy-Duty Working Device
Enhancing the durability and lifespan of the upper structure and working device. Improved tflexibility, durability, and wear resistance of the bushings. 6.55m heavy-duty boom, 2.9m arm, 2.79m³ rock bucket, ensuring excellent compatibility.
Hi-Grade Hydraulic Hoses (Significant Improvement in Heat Resistance and Durability)
Compared to regular hydraulic hoses, the lifecycle of Hi-Grade hydraulic hoses has been increased by 3-4 times, leading in improved reliability for excavators.
One-key Emergency Stop
The one-key emergency stop significantly enhances safety.
