Core Advantages

1. Efficient Power System & Excellent Fuel‑Saving Performance

Powered by proven CAT C4.4 turbo diesel engine, net power reaches 105.6 kW (142 hp) @2000 rpm卡特彼勒. Equipped with Power / Smart dual working modes, the machine automatically matches engine and hydraulic output according to site load conditions, greatly cutting fuel consumption without sacrificing working efficiency. Auto‑idle function reduces fuel waste during standby status. Large 390 L fuel tank supports long‑duration continuous operation and lowers refueling frequencyCat. Operating weight is 19 800‑20 500 kg, providing strong digging and lifting capacity while maintaining convenient road transport for frequent site transfers卡特彼勒.

2. Advanced Electro‑Hydraulic System & Reliable Working Performance

Adopts new‑generation electronic‑controlled load‑sensing hydraulic system with precise flow‑pressure matching, achieving fast response, smooth compound movements and high operation accuracy. Main hydraulic maximum flow reaches 429 L/min, main system pressure 35 MPa, effectively reducing invalid energy loss and improving overall cycle efficiency卡特彼勒. Key working parameters in 20‑ton segment: ‑ Maximum digging depth: 6 430 mmCat ‑ Maximum ground‑level reach: 9 860 mmCat ‑ Maximum dumping height: 6 490 mmCat ‑ Standard bucket capacity: 0.93‑1.05 m³卡特彼勒 ‑ Main hydraulic system pressure: 35 MPa卡特彼勒

Two‑speed travel system balances traction and traveling speed, adapting to slopes, muddy roads and rocky ground. Reinforced heavy‑duty undercarriage improves dust‑proof and anti‑corrosion performance, extending service life of track shoes, rollers and idlers.

3. Human‑Centered Cab & Practical Safety Configuration

ROPS/FOPS certified enclosed cab meets international roll‑over and falling‑object protection standards. Ergonomic interior layout is fitted with pilot‑control joysticks for light‑weight manipulation, reducing operator fatigue during long‑hour intensive shifts. 8‑inch touch‑screen monitor provides intuitive machine data display and fault‑self‑diagnosis function. Large‑area tempered glass offers panoramic view. Viscous vibration‑isolation mounting reduces cab noise and body vibration. Adjustable suspension seat plus optional automatic air‑conditioning create comfortable working environment under high‑temperature or cold climate. 360‑degree surrounding camera system is optional for safer site operation.

4. Reinforced Structure & Low‑Cost Daily Maintenance

Boom, stick and chassis key stress‑bearing components adopt high‑strength wear‑resistant steel, improving impact‑resistance and torsion‑resistance for mixed‑condition jobs. Hydraulic pipelines and joints apply upgraded sealing technology to prevent oil leakage and impurity invasion, lowering component failure rate. Centralized ground‑level maintenance layout enables easy access to filters, oil filling ports and inspection ports via large side service doors, saving inspection labor and time costs. With CAT mature industrial design, 320GX features low failure rate and high attendance rate, effectively reducing total equipment ownership cost.

5. Rich Attachment Compatibility & Wide‑Condition Adaptability

Supports quick‑coupler fast replacement of various working tools to satisfy multi‑scene operation demands: ‑ Standard digging buckets, heavy‑duty wear‑resistant buckets, rock buckets (0.85‑1.20 m³) ‑ Hydraulic breakers for concrete crushing and light demolition ‑ Hydraulic thumbs for bulk‑material sorting and handling ‑ Auger drill for foundation hole‑digging and piling ‑ Grading buckets and rippers for land leveling and trench trimming

Diversified attachments realize flexible switching between earth‑digging, crushing, demolition and fine finishing work, maximizing equipment utilization rate.
