Product Description

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.

Questions You May Have

Quick answers about products, ordering, delivery, and support

What scenarios are mini-excavators suitable for?

With their compact bodies and zero-tail swing design, they are ideal for indoor demolition, basement construction, orchard hole-digging, foundation work for rural self-built homes, garden renovations, and ditch dredging. They can access narrow paths, greenhouses, and tight alleyways, operating effectively in spaces where standard large excavators cannot fit. They are suitable for both personal home use and rental businesses.

Can the excavator use different attachments? Is it a multi-purpose machine?

Yes. Equipped with a standard quick-hitch coupler, it allows for rapid switching between accessories such as hydraulic breakers, timber grapples, augers, compactors, and sweepers. It can handle tasks like digging, wall demolition, timber handling, drilling, and ground leveling. You don't need to purchase multiple machines; a single unit can handle various projects, reducing your initial investment.

Will the tracked excavator get stuck or slip in mud or on slopes?

No. The widened and lengthened tracks increase the ground contact area, providing strong traction. It moves stably across riverbanks, paddy fields, steep slopes, and soft, rain-soaked ground without easily slipping or sinking. Its off-road performance far exceeds that of wheeled models, offering a distinct advantage on complex outdoor job sites.

Can a complete beginner quickly learn to operate the excavator?

It is easy to learn. The machine features smooth hydraulic controls and intuitive joystick operation. Free hands-on training is provided upon purchase, allowing you to master basic operations—such as digging, rotating, and backfilling—in a short time. The cab offers excellent visibility and operator comfort, minimizing fatigue during long shifts.

Is daily maintenance and servicing difficult? Are spare parts easy to find?

Maintenance is straightforward; routine upkeep requires only the periodic replacement of the oil filter. Parts are widely available on the market and service centers are plentiful—meaning components can be purchased in towns and counties without the need for long-distance travel for after-sales service. The machine features a robust design, ensuring reliable operation for over ten thousand hours without major breakdowns, provided standard maintenance is followed.

Does this mini excavator have high fuel consumption, and how much does it cost to run for a day?

It is equipped with a small diesel engine that consumes only 1–2 liters of fuel per hour; with an average workday of 8 hours, the fuel cost is just a few dozen yuan, making operating costs extremely low.
