Core Advantages

1. Reliable Power & Excellent Fuel‑Saving Performance

Powered by CAT C2.4 Turbo diesel engine, net power 40.9 kW (54.8 hp), compliant with EU Stage V / EPA Tier 4 Final emission standards. Equipped with auto‑idle and auto engine shutdown functions to cut idle fuel waste. Extended service intervals reduce total ownership cost by up to 10%.

• Operating weight: 7505‑8120 kg
• Fuel tank capacity: 112 L
• Maximum bucket digging force: 56.5 kN
• Gradeability: 70% Great low‑speed torque enables tough digging, heavy lifting and slope operation, suitable for long‑hour continuous medium‑intensity work.

2. Intelligent Hydraulic System & Superior Working Performance

Adopts next‑generation variable‑displacement load‑sensing hydraulic system. Lifting, slewing and multi‑action efficiency improved by up to 20%. Standard Stick‑Steer joystick travel mode: one‑button switch between pedal‑lever control and joystick driving, reducing operator fatigue. Touch‑screen monitor supports adjustable hydraulic response to match different operators and working conditions.

Key working parameters:

• Maximum digging depth: 4642 mm
• Maximum ground‑level reach: 6830 mm
• Maximum dumping height: 4870 mm
• Standard bucket capacity: 0.28‑0.35 m³
• Main pump maximum flow: 167 L/min
• Main hydraulic system pressure: 28.5 MPa Heavy‑duty dozer blade with float function assists back‑filling, site cleaning and enhances whole‑machine stability. Short‑tail structure minimizes overhang when working near barriers.

3. Premium Sealed Cab & Comprehensive Safety Design

ROPS/TOPS certified sealed pressurized cab meets international safety standards for roll‑over protection. Ergonomic interior layout, adjustable wrist supports and heavy‑duty suspension seat deliver all‑day comfort. Optimized air‑conditioning system maintains pleasant environment under hot or cold weather. Large‑area glass plus rear‑view camera provides good all‑round visibility. Intelligent touch‑screen monitor displays real‑time machine data and fault alerts. Fluorescent retractable safety belt and work lamps are equipped as standard. Effective vibration & noise isolation lowers operator fatigue during long shifts.

4. Convenient Maintenance & Low Running Cost

All routine service check‑points are centrally arranged at ground‑level. Large opening service panels grant easy access to filters, oil filling ports and inspection points, saving maintenance time and labor cost. Upgraded hydraulic sealing reduces oil leakage and component wear. Remote fault diagnosis is supported. With mature industrial design, CAT 307.5 achieves low failure rate and high attendance rate, lowering comprehensive ownership cost.

5. Versatile Attachment Compatibility & Wide Adaptability

Quick coupler enables fast switching of various working tools to satisfy multi‑scenario demands:

• Standard digging bucket, heavy‑duty earth & rock bucket
• Hydraulic breaker for concrete demolition and rock breaking
• Hydraulic thumb / grapple for timber, scrap and bulk‑material handling
• Auger for foundation hole‑drilling and fence post installation
• Rake & grading bucket for landscaping and site finishing

Multiple attachments allow flexible switch among excavation, demolition, lifting and land‑shaping tasks, maximizing equipment utilization rate.
