Medium Excavator
Total Weight:
21000KG
Bucket Capacity:
1.0m³
Rated Power:
129Kw
Positioned as a 21-ton class crawler excavator and equipped with a 1m³ standard bucket, this machine offers digging force and operational efficiency perfectly suited for municipal construction, earthwork, and mining operations. It provides stable and practical overall performance.
Powered by a WP6 engine with a rated output of 129KW at 2200rpm, it delivers smooth and reliable performance. Combined with a turbocharged design, it maintains stable operation in complex environments such as high altitudes and low temperatures, meeting the needs of high-intensity continuous construction.
With a maximum bucket digging force of 140KN and an arm digging force of 99KN, supported by a 32MPa system pressure, it offers superior cutting and breaking capabilities. Combined with a slewing speed of 11-13rpm, movements are fluid and continuous, effectively increasing output per unit of time.
Core hydraulic components, including the main pump, main valve, and swing motor, are sourced from globally recognized brands. Utilizing dual-pump confluence technology, it enhances the flow supply to the boom, arm, and bucket for faster response times. Swing starts and stops are smooth, providing precise positioning while reducing vibration and impact.
Featuring a maximum digging radius of 9850mm, a digging depth of 6480mm, a digging height of 9410mm, and a dumping height of 6730mm, the machine covers a wide area. It easily handles diverse tasks such as deep foundation excavation, high-reach unloading, and site leveling.
The boom is integrally welded and treated with precision boring and shot peening for high structural strength. Forged structures at the arm articulation points ensure even stress distribution. The bucket is designed with wear-resistant steel and thickened side plates to handle heavy-duty conditions, reducing wear and failure rates.
The cabin offers a wide field of vision with minimal blind spots. Control devices are laid out according to ergonomic principles, and the joysticks are light and easy to handle. Equipped with tempered glass, sunshades, an HVAC system, and comfortable seating, it reduces fatigue during long shifts and enhances operational safety.
Equipped with an electric throttle and an auto-idle function, the engine automatically drops to idle after 5 seconds of inactivity, effectively reducing fuel consumption and noise. A large-screen LCD monitor provides real-time monitoring of RPM, water temperature, and oil pressure, keeping the operating status clear at a glance.
All filters are arranged for quick ground-level access. The large-capacity fuel tank and spacious toolbox support long-term continuous operation. Built with reliable components, the machine features longer maintenance intervals, reducing downtime and overall operation and maintenance costs.
With a maximum gradeability of 30°, overall dimensions of 9590×2980×3185mm, a tail swing radius of 2880mm, and a minimum ground clearance of 470mm, the machine offers excellent passability and strong site adaptability.
