45 Ton heavy-duty crawler excavator
Superior Heavy-Duty Breakout and Traction Power：This model stands out for its exceptional capability in the most demanding conditions. With a formidable 290 kN bucket digging force and a class-leading 330 kN drawbar pull, it delivers unmatched power for breaking through hard soil, deep excavation, and applications requiring immense pushing force. This, combined with its 45-ton operating weight, provides superior stability and resistance to buckling under extreme loads, setting a new benchmark for brute-force applications.
Optimized for High-Volume, Large-Scale Earthmoving：Engineered as a true high-volume earthmover, this machine features a larger standard bucket capacity (2.0–2.2 m³) supported by a high-flow hydraulic system. Its design prioritizes extensive reach and clearance, with a maximum dump height of 7.6 meters and a digging radius exceeding 12 meters, enabling it to efficiently load large haul trucks and work over wide areas from a single position, maximizing cycle efficiency on massive sites like mines and major quarries.
This heavy-duty 45-ton excavator is engineered for the most demanding large-scale projects, delivering superior power and capacity. Driven by a robust 250 kW Cummins QSM11 engine and a high-flow hydraulic system, it generates formidable digging forces (290 kN bucket) to efficiently handle larger 2.0-2.2 m³ buckets. Its expanded footprint and long reach provide exceptional stability and extensive working ranges, including a digging depth of 7.8 meters and a ground-level reach of 11.8 meters. Furthermore, with its powerful 330 kN drawbar pull, high gradeability (35°), and large 650-liter fuel tank, it offers outstanding traction on extreme terrain and extended operational endurance, ensuring high productivity and reliability in the toughest mining and infrastructure applications.
Engineered for Continuous High-Productivity Cycles
Beyond peak power, this model is built for sustained output. The high-capacity 650L fuel tank and efficient engine design significantly extend uninterrupted work periods, directly reducing non-productive refueling downtime. The combination of a fast 9.3 r/min swing speed and a powerful yet stable travel system ensures quick repositioning and smooth transitions between digging and dumping cycles, driving higher overall daily productivity.
Robust Design for Demanding Environments & Operator Efficiency
Built to endure the toughest job sites, it features a reinforced undercarriage with wide 600 mm track shoes for superior ground flotation and longevity on abrasive surfaces. The design incorporates high-capacity cooling and filtration systems to maintain performance in high ambient temperatures. Furthermore, the precise hydraulic control system and a spacious, ergonomic cab enhance operator comfort and control accuracy, reducing fatigue and enabling peak performance during long shifts.
Precision Control with Advanced Hydraulic System
The dual-variable piston pump hydraulic system delivers not only high flow but also precise and responsive control. This allows for smooth, coordinated movements, enabling operators to perform delicate grading, precise trenching, and efficient loading with minimal material spillage, enhancing overall job quality and reducing rework.
Enhanced Stability for Safe and Efficient Operation on Slopes
With a wide 2,760 mm gauge and a long 5,335 mm track length, this machine provides an exceptionally stable base. This superior geometry, combined with its substantial operating weight, significantly increases safety and control when operating on its maximum 70% (35°) gradeability, allowing for productive work on slopes that would challenge less stable equipment.
Service-Friendly Design for Reduced Maintenance Downtime
Key design elements prioritize serviceability. Strategically placed service points, modular components, and a clear layout of systems (evident in the detailed capacity specs for each fluid) facilitate quicker daily checks, routine maintenance, and major repairs. This thoughtful engineering minimizes machine downtime, ensures higher availability, and helps control long-term maintenance costs.
