Core Advantages

1. Reliable Power & Outstanding Fuel‑Saving Performance

Powered by mature CAT C4.2 ACERT diesel engine, net power reaches 86 kW (115 hp). Multi‑power working modes allow operators to switch between heavy‑load mode and economy mode according to site requirements. Auto‑idle function reduces unnecessary fuel consumption during standby. Large 240 L fuel tank supports long‑time continuous operation and minimizes refueling downtime. Operating weight is 14 600‑15 800 kg, providing solid digging and lifting capacity while keeping good transport mobility for frequent job‑site transfers.

2. Load‑Sensing Hydraulic System & Excellent Working Efficiency

Adopts advanced load‑sensing hydraulic system with precise flow‑pressure matching, achieving fast response, smooth combined actions and high operation accuracy. It effectively cuts invalid energy loss and improves overall cycle efficiency. Key working parameters perform well within 15‑ton segment: ‑ Maximum digging depth: 5 170 mm ‑ Maximum ground‑level reach: 7 720 mm ‑ Maximum dumping height: 6 180 mm ‑ Standard bucket capacity: 0.55‑0.86 m³ ‑ Main hydraulic system pressure: 34.3 MPa

Two‑speed travel system balances traction and traveling speed, adapting to slopes, muddy 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 & Complete Safety Configuration

ROPS/FOPS certified enclosed cab meets international roll‑over and falling‑object protection standards. Ergonomic interior layout is equipped with pilot control joysticks for light‑weight operation, relieving operator fatigue in long‑hour shifts. Large tempered glass provides broad panoramic vision. Vibration‑isolation mounting lowers in‑cab noise and body vibration. Adjustable suspension seat plus optional automatic air‑conditioning create comfortable working environment under high‑temperature or cold conditions. Built‑in intelligent monitoring instrument supports real‑time machine status display and basic fault self‑diagnosis.

4. Reinforced Structure & Economical Daily Maintenance

Boom, stick and chassis key stress‑bearing components adopt high‑strength wear‑resistant steel, enhancing impact‑resistance and torsion‑resistance for mixed‑condition jobs. Upgraded sealing for hydraulic pipelines and joints reduces oil leakage and impurity invasion, lowering component failure risk. Centralized ground‑level maintenance points for filters, oil ports and inspection ports are easy to access via large side service doors, saving daily inspection labor and time. Benefiting from CAT mature industrial design, 315D2 features low failure rate and high attendance rate, reducing total 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 (0.5‑0.9 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 among earth‑digging, crushing, demolition and fine finishing work, maximizing equipment utilization rate.
