420LC-9 41-Ton Extra Heavy-Duty Mining Crawler Excavator
High-Output Heavy Machinery Built for Mining, Quarrying & Extreme Earthmoving
The 420LC-9 crawler excavator is engineered to deliver ultimate performance and heavy breakout force in the most grueling environments, including open-pit mining, hard rock quarrying, and high-volume earthmoving projects. Operating at a formidable working weight of 41,200 kg (41.2 Tons), this 40-ton class heavy-duty machine guarantees exceptional stability, structural rigidity, and swift loading cycle times under extreme loads.
Powered by a high-torque 238 kW (320 HP) @ 2000 rpm heavy-duty diesel engine and driven by a high-pressure, heavy-flow hydraulic system, the 420LC-9 effortlessly operates its massive 2.0 m³ rock bucket to achieve maximum daily tonnage production at lower operational costs per ton.
Key Features & Product Advantages
- High-Torque Heavy Industrial Engine: Driven by a robust 6-cylinder turbocharged engine delivering 238 kW (320 HP) @ 2,000 rpm. Engineered to provide high low-end torque, superior cold-starting capabilities, and reliable operation in high-altitude or dusty mining environments.
- Heavy-Duty High-Flow Hydraulics: Equipped with a precision-tuned hydraulic main pump and control valve system designed for fast compound movements, responsive joystick feel, and minimal hydraulic power loss during continuous heavy lifting and rock digging.
- Reinforced Heavy Slew Drive: Integrated with a high-durability swing motor that delivers exceptional rotation torque, fast 360-degree slew cycles, and strong braking stability on steep quarry inclines.
- Massive 2.0 m³ Mining Bucket: Standard equipped with a high-capacity 2.0 m³ heavy-duty rock bucket constructed from wear-resistant steel plates, optimized for high fill factors and rapid dump truck loading.
- Unmatched Operation Autonomy: Features an enormous 610 L fuel tank and 390 L hydraulic fluid tank, allowing non-stop multi-shift continuous operations on remote job sites without frequent refueling downtime.
Why Choose the 420LC-9 Heavy Mining Excavator?
1. Mine-Grade Heavy X-Frame Undercarriage
Built with thick-gauge high-tensile steel, reinforced boom and arm assemblies, and heavy-duty track rollers, the 420LC-9’s long-crawler (LC) chassis absorbs heavy torsional shocks and recoil when tearing through hard rock formations.
2. High Productivity & Lower Cost-Per-Ton
The combination of a 2.0 m³ high-capacity bucket and rapid hydraulic cycle times allows operators to load 30-40 ton mining dump trucks in fewer passes, significantly reducing cycle times and driving down Total Cost of Ownership (TCO).
Ideal Applications
- Open-Pit Mining, Overburden Stripping & Ore Extraction
- Heavy Rock Quarrying & Crusher Feed Operations
- Mega Infrastructure, Foundation Digging & Dam Construction
- Heavy Rock Breaking & High-Impact Demolition
