Core Advantages

1. Strong Power Output & Outstanding Fuel‑Saving Performance

Powered by the mature CAT C9.3B diesel engine, the CAT 345GC reaches a rated net power of 258 kW (346 hp)Finning Ca.... Matched with intelligent engine management logic, it dynamically adjusts power delivery against actual working conditions, lifting fuel efficiency by up to 25% versus older generation models while maintaining powerful digging torqueTrakindo U.... The large‑volume 600 L fuel tank supports extended non‑stop operation and cuts downtime caused by frequent refuelling. Operating weight hits 42,200 kg, delivering superior digging and loading capability to satisfy long‑hour high‑intensity earth‑rock working scenarios.

2. Upgraded Intelligent Hydraulic System & Excellent Working Parameters

Adopting next‑generation load‑sensing variable hydraulic system plus independent pilot control, the CAT 345GC realizes rapid response, smooth movements and high‑precision operation. Flow‑pressure precise matching reduces useless energy loss and raises overall job efficiency. Key working specifications:

• Maximum digging depth: 7,200 mm
• Maximum ground‑level reach: 11,290 mm
• Maximum dumping height: 7,210 mm
• Standard heavy‑duty bucket capacity: 2.41 m³ (range 2.2‑2.6 m³ for rock bucket)Tractafric...
• Main hydraulic pressure: 35 MPa, maximum system flow: 630 L/min

Equipped with two‑speed travel system and heavy‑duty reinforced drive assembly, it copes well with slopes, muddy ground and rocky terrain. The fully sealed heavy‑duty undercarriage resists dust, silt and corrosion effectively, greatly prolonging service life of track shoes, rollers and other wearing components.

3. ROPS/FOPS Certified Comfort‑Oriented Cab & Full‑Range Safety

The cab complies with international ROPS/FOPS roll‑over and falling‑object protection certification standards. Fully ergonomic interior layout comes with upgraded multi‑function joysticks and one‑touch control buttons, lowering operator fatigue during long‑shift heavy‑duty work. Large tempered glass windows plus panoramic rear‑view system provide 360° all‑round visibility. Built‑in vibration isolation and noise‑reduction structure suppress cab noise and body vibration. Fully adjustable suspension seat with lumbar support and optional automatic constant‑temperature air‑conditioning deliver comfortable working environment under extreme hot/cold weather. Intelligent monitoring panel and built‑in fault self‑diagnosis keep operators informed of real‑time machine status.

4. Reinforced Heavy‑Duty Structure & Reduced Maintenance Expense

Boom, stick, chassis and all major stress‑bearing parts are strengthened with high‑strength wear‑resistant steel material, with enhanced anti‑impact and anti‑torsion performance, perfectly adapted to rock breaking, quarry loading and other harsh conditions. Updated sealing tech for all hydraulic hoses and joints prevents oil leakage and foreign‑matter ingress to cut component failure rate. Centralized, ground‑level accessible service points for filters, oil ports and testing ports save daily maintenance time and labour cost. Maintenance cost can be lowered up to 35% compared with legacy models, featuring low failure rate and high machine attendance rate, cutting total ownership cost significantly.

5. Rich Attachment Compatibility & Wide Working‑Condition Adaptability

Quick‑coupler interface supports fast swap of diverse working tools for multi‑scenario operations: ‑ Standard large‑capacity buckets, heavy‑duty wear‑resistant buckets, rock buckets (2.2‑2.6 m³) ‑ Heavy‑duty hydraulic breakers for rock crushing & demolition ‑ Hydraulic thumbs for bulk material sorting & handling ‑ Auger drills for foundation piling & hole drilling ‑ Rippers & grading buckets for land levelling and trench finishing

Diversified attachments enable flexible switch between quarry loading, heavy earthwork, demolition, foundation construction and fine finishing tasks, maximizing equipment utilization rate.

Typical Application Scenarios

1. Mining & Quarry OperationsIdeal for open‑pit mine auxiliary tasks, quarry rock loading, stockpiling and slag clearance. High breakout force and reinforced structural design handle heavy rock‑ore conditions, matching large haul trucks for high‑throughput loading and transportation.
2. Large‑Scale Infrastructure ConstructionApplied in highway, railway, bridge and airport projects for mass earth excavation, embankment filling, foundation trenching and site levelling. Stable high output shortens construction cycles for mega‑projects.
3. Water Conservancy & Hydropower ProjectsPerforms reliably in river dredging, reservoir excavation, dike reinforcement and flood‑control works. Adapts to wetland and muddy terrain with stable running and good anti‑slip performance.
4. Urban Renewal & Heavy Demolition WorksSuitable for large‑scale old‑building demolition, foundation reconstruction, municipal pipeline trenching and urban site renovation, achieving high‑efficiency construction under complex urban surroundings.
5. Industrial Park & Large‑Area Land DevelopmentCovers industrial zone site preparation, farmland consolidation, port yard stacking and other land‑development assignments, meeting requirements of prolonged high‑intensity operation.
