Performance Efficiency Durability Safety Comfort

Built for Maximum Performance

The R390 LC-9 Hyundai excavator is meant to deliver the highest standard of performance in the toughest environments. This machine delivers top-level performance, faster operation cycles and ease-of-operation.

Performance:

  • Powerful Engine

    The water-cooled, 6-cylinder turbocharged diesel engine delivers strong, reliable, and efficient performance with low emissions, built to withstand extreme heat, humidity, and dust without compromising productivity.

    Powerful Engine

  • Auto Power Boost System

    It automatically boosts digging power during peak loads, delivering extra force when high pressure is detected.

    Powerful Engine

  • Auto Boom & Arm Regeneration

    Auto Arm & Boom Regeneration recirculates hydraulic energy for smoother, faster arm operation while preventing cavitation and boosting overall performance.

    Powerful Engine

  • High Bucket Digging Forces

    The Hydraulics and attachments are designed to offer high digging forces.

    Powerful Engine

Efficiency:

  • 7” Wide LCD Touch Screen with Mode Selection

    It maintains optimal machine health by displaying key parameters like oil and coolant temperatures, maintenance alerts, and other vital data, while allowing the operator to choose between multiple power and work modes.

    Powerful Engine

  • One-Touch Deceleration & Auto-Idle

    One-touch deceleration on the LH joystick lowers engine RPM to save fuel. The Auto Idle function reduces RPM after 4 seconds of inactivity, cutting fuel use and operating costs.

    Powerful Engine

  • Auto Boom & Swing Priority

    The auto-piloted swing priority boosts hydraulic flow to the swing circuit, enabling faster swing cycles for higher productivity and profitability.

    Powerful Engine

  • Self-diagnostics System

    The Main Control Unit automatically shows malfunctions on the LCD, making machine health checks and troubleshooting easy.

    Powerful Engine

Durability :

  • Heavy Duty Boom & Arm With Reinforced Ribs

    Made with high-tensile steel, the boom and arm are reinforced with bearings, baffle plates, and ribs to resist wear and prevent damage, extending component life.

    Powerful Engine

  • Reinforced Upper & Lower Frame

    The frames withstand heavy shocks and workloads, extending overall machine life.

    Powerful Engine

  • Heavy Duty Undercarriage

    Side member reinforcement protects the idler in tough terrain, while the heavy-duty track shoe ensures greater stability and durability.

    Powerful Engine

  • Reinforced Bucket

    The bucket uses high-tensile steel with wear-resistant blades, delivering strong digging force and reinforced protection against wear from hard stones.

    Powerful Engine

Safety :

  • Automatic Engine Overheat Prevention

    It monitors coolant temperature and automatically reduces engine speed to prevent overheating and machine damage.

    Powerful Engine

  • Anti-Restart System

    This feature prevents the starter from engaging while the engine is running, protecting the engine from accidental damage.

    Powerful Engine

  • Counterbalance & Holding Valve

    The counterbalance valve provides hydrostatic braking on slopes, while the holding valve locks attachments to prevent gravity-induced drift.

    Powerful Engine

  • Anti-Slip Pads & Handrail

    Anti-slip pads ensure firm footing, while handrails offer added support and safety when entering or exiting the cabin.

    Powerful Engine

Comfort :

  • Air Conditioned Cabin

    The spacious Air Conditioned cabin creates a very comfortable working environment for the operator.

    Powerful Engine
