Powered by the reliable CAT C9.3B diesel engine, the CAT 340GC delivers a rated power of 239 kW (320 hp) with optimized speed matching technology, achieving strong power output while significantly reducing fuel consumption. Equipped with an intelligent engine management system, it automatically adjusts power output according to working conditions, realizing perfect balance between heavy-load performance and energy saving. The large 600 L high-capacity fuel tank supports ultra-long continuous operation, effectively reducing frequent refueling downtime and improving overall construction efficiency. With an operating weight of 39,800 kg, the machine features super-strong digging and loading capacity, meeting the high-intensity operation demands of large-scale earthwork and rock working conditions.
2. Intelligent Hydraulic System & Superior Working Performance
The CAT 340GC adopts a new-generation intelligent variable hydraulic system with independent pilot control and load-sensing technology, achieving faster response, smoother operation, and higher work precision. The system realizes precise matching of flow and pressure, reducing invalid energy loss and greatly improving construction efficiency. Its core working parameters are outstanding in the same tonnage class:
- Maximum digging depth: 7,390 mm
- Maximum ground-level reach: 10,580 mm
- Maximum dumping height: 7,240 mm
- Standard bucket capacity: 1.9–2.4 m³
- Main hydraulic system pressure: 35 MPa, maximum flow rate: 320 L/min
Equipped with a high-efficiency two-speed travel system and reinforced drive device, it can adapt to complex terrain such as slopes, muddy roads, and rocky ground. The fully sealed heavy-duty undercarriage effectively resists dust, sediment and corrosion, greatly extending the service life of track shoes, rollers and other wearing parts.
3. Premium Operator-Centric Cab & Full-Scenario Safety Design
The CAT 340GC is equipped with a ROPS/FOPS fully certified high-grade cab, which meets international safety standards for falling object protection and rollover protection. The interior adopts a fully ergonomic layout, with newly upgraded multi-functional intelligent operating handles and one-touch control buttons, which are simple and labor-saving, effectively reducing operator fatigue during long-hour high-intensity operations. The large-area tempered glass window and panoramic rear-view system provide 360° unobstructed visibility. The built-in high-efficiency vibration isolation and noise reduction system greatly reduces cab noise and body vibration. The fully adjustable luxury suspension seat with lumbar support and optional automatic constant-temperature air conditioning create a comfortable working environment in high-temperature, low-temperature and harsh weather conditions. It is also equipped with intelligent monitoring instruments and fault self-diagnosis functions to ensure real-time grasp of equipment operating status.
4. Reinforced Durable Structure & Low Maintenance Cost
The whole machine is made of high-strength wear-resistant steel and thickened heavy-duty structural parts. The boom, arm and chassis key stress parts have been strengthened and optimized, with strong impact resistance and torsion resistance, fully adapting to harsh working conditions such as rock breaking and heavy earthwork. All hydraulic pipelines and joints adopt upgraded sealing technology to prevent oil leakage, dust and sediment invasion, effectively reducing component wear and failure rate. The equipment is designed with centralized and open maintenance points, including filters, oil filling ports, detection ports and other core maintenance parts, which are easy to access and operate, greatly saving daily maintenance time and labor costs. With CAT’s mature and stable industrial design, the 340GC has low failure rate and high attendance rate, effectively reducing the total equipment ownership cost.
5. Strong Attachment Compatibility & Wide Adaptability
The CAT 340GC supports fast-coupler quick replacement of various working tools, with strong working condition adaptability, which can meet the operation needs of multiple scenarios:
- Large-capacity standard buckets, wear-resistant heavy-duty buckets, and rock buckets (1.8–2.6 m³)
- Large hydraulic breakers for rock crushing and demolition operations
- Hydraulic thumbs for bulk material sorting and handling
- Auger drilling equipment for foundation piling and hole digging
- Grading buckets and rippers for land leveling and trench finishing
Diversified attachments enable the machine to switch freely between heavy earthwork, rock operation, demolition, foundation construction and fine finishing, maximizing equipment utilization rate.
