Mini Excavator – Compact Power and Precision for Any Job Site

Designed for professionals who demand maximum efficiency in confined or hard-to-reach areas, this mini excavator combines compact dimensions, robust performance, and advanced hydraulic control to tackle small-to-medium construction, landscaping, and utility projects with ease. Weighing 3.7 tons, this machine fits comfortably into tight urban environments, narrow alleys, and restricted work zones while maintaining stability and operator confidence. Its overall length of 5.45 m, width of 1.53 m, and height of 2.408 m allow easy transportation and deployment, while a rear swing radius of 1.538 m ensures that rotation and excavation can be performed efficiently without repositioning the base frequently.

The excavator is powered by a reliable YANGDONG, CHANGCHAI, or YANMAR engine, producing 36.8 kW of power, delivering strong torque for digging, lifting, and loading operations. Coupled with a load-sensing hydraulic pump operating at 20 MPa and a maximum flow of 95 L/min, the system provides smooth, responsive, and energy-efficient hydraulic movements, reducing fuel consumption and enhancing precision. The 60 L hydraulic oil reservoir supports consistent performance during long shifts, while the 80 L fuel tank minimizes downtime for refueling, making it ideal for extended on-site operations.

Equipped with a 0.12 m³ digging bucket, the machine delivers a digging force of 24.2 kN, enabling efficient soil excavation, trenching, foundation work, and small-scale demolition tasks. It achieves a maximum digging depth of 3.735 m, a maximum digging height of 5.172 m, and a maximum dumping height of 3.585 m, allowing precise material placement across a variety of applications. With a maximum digging reach of 5.856 m and a vertical wall digging depth of 2.409 m, this excavator can perform complex operations along walls and in tight spaces with ease.

Operator convenience and maneuverability are central to this design. The machine provides dual-speed travel, reaching 4.6 km/h in low gear and 8 km/h in high gear, ensuring efficient movement around the site. Its boom and arm combination (2.8 m boom, 1.7 m arm) gives extended reach without the need to reposition frequently, while the 11.5 rpm swing speed allows quick rotation to access multiple working positions. The minimum swing radius of 2.146 m and the minimum turning radius at maximum height of 3.975 m provide unparalleled flexibility when navigating obstacles or working in congested areas.

Stability and terrain adaptability are ensured by a high ground clearance of 605 mm under bob-weight and a minimum ground clearance of 208 mm, allowing confident operation on uneven terrain or slopes. The excavator maintains excellent traction and low ground pressure, protecting surfaces in sensitive environments such as landscaping projects, urban streets, or small construction sites.

Safety and precision are further enhanced by the advanced hydraulic system, enabling smooth, predictable bucket and boom operation. The machine’s vertical lifting force of 800 kg and horizontal lifting force of 520 kg expands its versatility for handling small loads or assisting in installation tasks, while the robust undercarriage and durable tracks support secure operation on varied terrain.

Compact yet powerful, this mini excavator is highly adaptable, offering a combination of mobility, digging force, and operational precision that makes it suitable for municipal works, landscaping, pipeline installation, small construction projects, and other applications where larger machines cannot operate. Its optimized hydraulic efficiency, reliable engine performance, and intuitive controls ensure that operators can achieve high productivity with minimal effort, making this excavator an indispensable tool for contractors working in restricted environments.

In summary, this mini excavator balances strength, reach, maneuverability, and fuel efficiency within a compact design, delivering exceptional performance across a wide range of tasks while maintaining ease of transport and operation. Its versatile capabilities and reliable construction make it an ideal solution for contractors seeking a powerful, precise, and highly maneuverable machine for challenging and confined job sites.
