The 3.5-ton mini excavator is a high-performance machine specifically engineered for small-to-medium scale construction, landscaping, agricultural land improvement, and municipal engineering projects. Powered by a Xinchai 490 engine, it delivers robust and stable power within a compact overall footprint. Standard features include a boom swing function, with an optional retractable track system available; furthermore, it is equipped with pilot-operated travel controls and an automatic shifting system. By effectively balancing operational efficiency, precision control, and adaptability to complex working conditions, this machine serves as the ideal choice for small construction teams, landscaping contractors, and municipal maintenance crews.

Powerful Performance, Stable and Reliable

Equipped with the Xinchai 490 engine, featuring a rated power output of 36.8 kW. It delivers robust power for starting, excavating, and climbing, effortlessly handling challenging conditions such as hard soil and gravel.

The engine utilizes a mature and reliable technical design; spare parts are standardized and easy to source, making maintenance simple and hassle-free—significantly reducing long-term operating costs.

Power output is smooth and stable. When combined with an optimized hydraulic system, operational movements are fluid and precise—free from noticeable jerks—thereby enhancing both construction efficiency and quality.

Standard Side-Swing Function: No Blind Spots in Confined Spaces

Features a standard side-swing function allowing the boom to pivot left and right. This enables effective operation right alongside walls, fences, and corners without the need to repeatedly reposition the machine, effectively solving the challenges of working in cramped job sites and narrow lanes.

An optional retractable track system is available, allowing the track width to be adjusted according to site conditions. Tracks can be widened on soft ground to enhance stability, or retracted in narrow spaces to improve maneuverability, making the machine adaptable to a wide variety of complex terrains.

Pilot-Operated Travel Control: Precise and Effortless Operation

Equipped with a pilot-operated travel control system, the control levers are light and effortless to operate, offering significantly enhanced precision—allowing even novice operators to quickly master the controls.

Travel movements are highly responsive, enabling fine-tuned operations. Whether excavating trenches or grading sites, the machine allows for precise control over the working trajectory, thereby reducing the need for rework.

Automatic Gear Shifting: Efficient Handling of Complex Conditions

Features an automatic high/low-speed shifting system. When traveling on flat ground between locations, it automatically switches to high-speed mode to reach the job site quickly, saving transit time.

If obstacles or muddy terrain are encountered while traveling at high speeds, the system automatically shifts to a low-speed, high-torque mode. This provides an instant surge in power, allowing the machine to easily extricate itself without slipping—balancing both operational efficiency and terrain adaptability.

Durable and Reliable Design: Lower Long-Term Operating Costs

The tracks are constructed from wear-resistant materials, making them suitable for complex ground conditions such as gravel, construction sites, and muddy terrain; they offer a long service life and are highly resistant to damage.

The chassis features a robust structure. Combined with an optimal ground clearance and track design, the machine remains exceptionally stable during operation—minimizing the risk of tipping over and ensuring operator safety.

Key components feature a water-resistant and dustproof design, making them well-suited for outdoor construction environments. This reduces the likelihood of mechanical failure and extends the overall service life of the equipment.

With its compact body, robust power, and versatile expandability, the 3.5-ton mini-excavator is ideally suited for a wide range of small-to-medium-scale work scenarios:

Municipal Utility Engineering

Excavation and backfilling of urban cable trenches, water supply and drainage pipelines, and gas mains; performs effortlessly in confined spaces such as narrow sidewalks and alleyways; features a side-swing boom function that allows for easy operation right alongside walls, enabling the efficient completion of municipal utility network renovation projects.

Renovation of Older Residential Communities

Renovation of community roads, landscape upgrades, parking space modifications, and separation of rainwater and sewage systems; its compact size allows for agile operation in open spaces between buildings and through narrow passageways; when paired with a hydraulic breaker, it efficiently demolishes old pavement, while the bucket quickly excavates trenches—all with minimal disruption to residents' daily lives.

Landscaping and Garden Engineering

Q1: What is the purpose of the standard boom swing function?

A1: The boom swing function allows the main boom to pivot left and right, enabling operations right alongside walls, fences, and corners without the need to repeatedly reposition the machine. This resolves operational challenges in confined job sites and narrow passageways, significantly boosting construction efficiency and reducing the rate of rework.

Q2: What are the advantages of the optional retractable track system?

A2: The retractable track system allows the track width to be adjusted according to specific working conditions. On soft ground, the tracks can be widened to enhance machine stability and prevent the unit from getting stuck; in narrow spaces, the tracks can be retracted to improve maneuverability, allowing the machine to easily pass through narrow doorways and passageways, thereby adapting to a wide variety of complex terrains.

Q3: What is the difference between pilot-operated travel control and standard operation?

A3: Pilot-operated travel controls feature lightweight, low-effort control levers that offer significantly enhanced precision, enabling highly refined operations. Whether performing trench excavation or site grading, the operator can precisely control the machine's movement trajectory; this allows even novice operators to quickly master the controls, thereby reducing the rate of rework.
