Engineering Advantages
1. Factory-direct "stone handler" configurationThe Stone Handler specification provides comprehensive protection for the machine's undercarriage, essential for severe environments.
● Monolithic protection: the track frame is equipped with full-length steel screens (Full Track Guards). This design ensures the integrity of the track rollers and idlers by preventing rock ingress into the moving parts of the undercarriage.
● Traction and stability: the track shoes (heavy-duty steel plates bolted to the track links) feature a specialized double-grouser profile. This configuration provides the excavator with a stable stance on hard rock ledges and minimizes the risk of lateral sliding when operating on inclines.
2. Powertrain torque potentialAt the heart of the machine is the Hyundai D6AC-C engine, delivering performance characteristics optimized for heavy-duty cycles.
● Torque delivery: the power unit reaches its peak torque at just 1,400 RPM. This high torque allow the operator to efficiently handle high-density materials, maintaining smooth hydraulic movement even under maximum load.
● Operational autonomy: the fuel system, featuring mechanical injection and an in-line fuel pump, is designed for simplicity and ease of maintenance. This system ensures stable engine performance in remote locations and harsh climatic conditions.
3. Reinforced working equipmentThe boom and arm of the R380LC-9SH are engineered to withstand prolonged exposure to high dynamic and static stresses.
● Structural integrity: working equipment components are fabricated from thickened highgrade steel with internal structural reinforcements. This provides the necessary rigidity for extracting oversized rock fragments.
● Rock-duty attachment: the base specification includes a Heavy Duty (HD) Class Rock Bucket. It is reinforced with additional liner plates and equipped with side cutters, facilitating efficient penetration into dense faces and reducing abrasive wear on the shell's base metal.
4. Hydraulic performanceThe Kawasaki hydraulic system provides the machine with exceptional power and responsiveness.
● Penetration force: thanks to optimized kinematics and the Power Boost function, the bucket breakout force reaches 24.7 tons. This enables the direct excavation of Category IV-V soils and rock without prior loosening.
● Cycle efficiency: the high-output pump station ensures rapid execution of work cycles (boom hoist, swing) even with a fully loaded bucket, guaranteeing consistently high production rates per shift.
