The JGM9030-2 is a 2.8-ton excavator designed for compact construction sites. With an operating weight of 2,800 kg and a standard bucket capacity of 0.1 m³, it suits small-scale earthworks where access is limited. The machine features a 20 kW engine and a 18 MPa hydraulic system, providing sufficient power for digging and grading tasks in tight spaces.
The excavator includes a pilot control system and an adjustable dozer blade for improved stability and site preparation. It supports quick attachment changes for functions like breaking and trenching. The compact design, with a tail swing radius of 1,252 mm, allows operation in confined areas while maintaining a low ground pressure of 32 kPa.
Key Features
Compact Operating Weight
At 2,800 kg, the machine fits in narrow job sites. Its small footprint and 1,252 mm tail swing radius allow safe operation close to walls or obstacles without damaging surrounding structures.
Standard Dozer Blade
The adjustable dozer blade helps level ground and backfill trenches. It also increases machine stability during digging, reducing the need for separate grading equipment on small projects.
Pilot Control System
The pilot-operated controls provide smooth and precise movement. This reduces operator fatigue and allows for accurate digging and positioning, which is essential for detailed earthwork tasks.
Quick Attachment Change
The machine supports rapid swapping of attachments such as breakers and hoses. This versatility allows one unit to handle digging, breaking, and trenching, increasing overall job site efficiency.
Low Ground Pressure
With a standard ground pressure of 32 kPa, the rubber tracks distribute weight effectively. This protects soft ground surfaces and allows the excavator to work on sensitive terrain without excessive sinking.
Compact Dimensions
The 4,600 mm transport length and 1,420 mm width make the machine easy to transport on standard flatbeds. Its small size facilitates movement between job sites and storage in limited spaces.
Hydraulic System Capacity
The 18 MPa hydraulic system delivers 16.2 kN of bucket digging force. This provides adequate power for excavation and material handling, ensuring the machine can handle typical soil and rock conditions.
Where the JGM9030-2 Is Used
Residential Construction
Ideal for small house foundations and utility trenching. The compact size allows work in backyards and narrow streets where larger excavators cannot operate safely or fit through gates.
Landscaping and Grading
Used for shaping garden beds, installing irrigation lines, and leveling small plots. The dozer blade and precise controls help create smooth surfaces for planting or paving preparation.
Utility Installation
Suitable for digging trenches for water, gas, and electrical lines in urban areas. The machine's ability to work close to existing infrastructure minimizes damage to surrounding structures.
Small Quarry Operations
Used for cleaning out small quarry faces and moving loose rock. The 0.1 m³ bucket and 16.2 kN digging force handle light rock breaking and material loading efficiently.
Site Cleanup
Effective for removing debris, leveling post-construction sites, and general earthmoving. The versatile attachment options allow the machine to adapt to various cleanup tasks quickly.

How to Choose the Right Configuration
Assess the JGM9030-2 for sites where a 2,800 kg machine fits transport limits. The 1,252 mm tail swing radius and 1,420 mm width allow work in narrow trenches or near structures. With a 0.1 m³ bucket and 16.2 kN digging force, it handles standard earthmoving and small-scale excavation tasks efficiently.
Check site access against the 4,600 mm transport length and 2,262 mm height. The 2.7 km/h travel speed suits short moves between work areas. Ensure the ground supports the 32 kPa ground pressure, and verify the 250 mm ground clearance is sufficient for the terrain to avoid undercarriage damage.
Evaluate hydraulic capacity for attachments. The 18 MPa system supports standard digging and dozer blade functions. If you require heavy breaking, confirm the 20 kW engine output matches your specific attachment requirements. The 23 L fuel tank allows for several hours of continuous operation before refueling.
Daily Operation and Maintenance
Check engine oil level daily; the 5 L capacity requires frequent monitoring during high-load digging cycles.
Inspect rubber tracks for wear and tension weekly to maintain the 32 kPa ground pressure and prevent slippage.
Verify hydraulic oil level in the 58 L tank before each shift to ensure consistent 18 MPa system pressure.
Clean the cooling system and check the 3.4 L coolant level to prevent overheating in high-temperature environments.
Frequently Asked Questions
