500LC-9 50-Ton Heavy Mining Crawler Excavator
Flagship Heavy Machinery Built for Mining, Heavy Quarrying & Massive Earthmoving
The 500LC-9 crawler excavator is engineered to deliver high breakout force and high material-moving capacity in the most demanding global applications, including open-pit mining, abrasive rock quarrying, and megaproject earthmoving. Operating at a heavy working weight of 50,000 kg (50 Tons), this flagship 50-ton machine combines exceptional structural strength, unmatched working stability, and rapid dump truck loading cycle times.
Driven by a high-displacement Doosan DE12TIS 6-cylinder turbocharged engine (254 kW / 340 HP), a precision-tuned Parker main control valve, a high-flow Rexroth hydraulic main pump, and a high-torque DOOSAN swing motor, the 500LC-9 effortlessly operates its massive 2.6 m³ heavy-duty rock bucket to achieve high daily production rates at a lower cost per ton.
Key Features & Product Advantages
- High-Displacement Doosan Powerhouse: Powered by the heavy-duty 11.1-liter Doosan DE12TIS engine, delivering 254 kW (340 HP) @ 2,000 rpm. Built for heavy continuous mining loads with massive low-end torque, high thermal efficiency, and reliable mechanical fuel injection tolerant to harsh operating environments.
- World-Class Hydraulic Synergy (Parker & Rexroth): Integrates a premier Parker main control valve with a high-pressure Rexroth main hydraulic pump, delivering ultra-smooth multi-function control, minimized pressure drop, and exceptional responsiveness under high load resistance.
- Heavy-Duty DOOSAN Swing Drive: Equipped with a high-durability DOOSAN swing motor, delivering powerful 360-degree rotation torque, rapid slew cycles, and rock-solid holding performance on steep quarry inclines.
- Massive 2.6 m³ Reinforced Mining Bucket: Standard equipped with an extra-large 2.6 m³ rock bucket manufactured from wear-resistant steel, optimized for high bucket fill factors and reduced loading passes for 30-50 ton mining trucks.
- Extreme Endurance Fuel & Hydraulic Storage: Built with a massive 610 L fuel tank and 390 L hydraulic fluid tank, guaranteeing multi-shift continuous operation on remote mining sites without constant refueling stops.
Why Choose the 500LC-9 Heavy Excavator?
1. Ultra-Durable Mining-Grade Undercarriage
Built with thick high-tensile steel plates, an extra-wide X-frame long crawler (LC) chassis, and heavy-duty track rollers, the 500LC-9 absorbs severe digging recoil and resists heavy torsional stress during heavy rock excavation.
2. High Mechanical Reliability & Low Downtime
Combining simple mechanical Doosan engine engineering with global mainstream hydraulic components (Parker, Rexroth, DOOSAN), standard filters and maintenance components are readily available worldwide, keeping maintenance costs low and operational uptime high.
Ideal Applications
- Open-Pit Mining, Overburden Stripping & Ore Excavation
- Large-Scale Heavy Quarrying & Crusher Feeding
- Infrastructure Megaprojects, Dam Foundations & Bulk Earthworks
- River Dredging, Heavy Rock Ripping & Demolition
