High Bucket Digging Forces
The Hydraulics and attachments are designed to offer high digging forces.
HYUNDAI
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.
Powerful Engine
The water-cooled, 4-cycle diesel, 6-cylinder in line, direct injection turbocharged, charge air cooled engine is built for power, reliability, efficiency and reduced emission. The engine is manufactured to perform in wide range of heat, humidity and dust conditions without compromising productivity.
Auto Power Boost System
It helps to meet extreme power requirement when working with peak loads. If high digging pressure is observed for more than 1 second, the controller automatically boosts digging forces to meet job condition.
Auto Boom & Arm Regeneration
Auto Arm & Boom regeneration helps to recirculate hydraulic energy from return line to pump supply line for smooth and fast arm operation. It prevents cavitation and enhances performance of machine.
7” Wide LCD Touch Screen with Mode Selection
It helps to maintain machine in optimum health by displaying key machine information like oil temperature, coolant temperature, maintenance checklists, and other such vital statistics. It also lets the operator choose between 3 power modes and 2 work m
One-Touch Deceleration & Auto-Idle
One touch deceleration switch on top of LH joystick lowers the engine RPM when selected. The saves fuel by regulating pump and engine. Auto Idle function moderates engine RPM to idle state when machine remains idle for 4 sec by enabling MCU to send a signal to engine. This in turn reduces fuel consumption and operation cost.
Auto Boom & Swing Priority
The auto-piloted swing priority increases hydraulic oil flow to swing circuit in combined operation, which leads to faster swing cycle for more productivity & profitability.
Self-diagnostics System
The Main Control Unit automatically displays machine malfunctions on the LCD monitor. This makes it very easy to check machine health and troubleshoot problems.
Heavy Duty Boom & Arm With Reinforced Ribs
Made with high tensile strength steel, the boom & arm are reinforced with steel bearings and internal baffle plates to withstand wear and tear, thus extending component life. Additionally the reinforced ribs are provided to prevent damage from lifted b
Reinforced Upper & Lower Frame
The frames are built to withstand tougher conditions by enduring external shocks and heavy workloads, thereby extending machine life.
Heavy Duty Undercarriage
Side Member reinforcement protects the idler from any damage in tough terrains. A heavy-duty track shoe provides better stability and durability on harsh terrains.
Reinforced Bucket
The bucket is made of high tensile strength steel and its blades are made of wear-resistant alloy steel. It offers a high digging force and features added reinforcement in plates and cutting section to prevent wear & tear from hard stones.
Automatic Engine Overheat Prevention
This feature monitors coolant temperature and automatically lowers engine speed if it overheats, preventing premature failure of the machine.
Anti-Restart System
This feature prevents the starter from restarting during engine operation if the operator accidently turns on the start key. Thus preventing accidental damage to the engine.
Counterbalance & Holding Valve
The Counterbalance Valve prevents the machine from rolling down on steep slopes by applying hydrostatic braking. The Holding Valve keeps attachments locked and prevents them from drifting due to gravity during prolonged overhanging.
Anti-Slip Pads & Handrail
Anti-slip pads provides a great floor grip to the operator and prevent skidding while working on the machine. Handrails provide additional support and safety to the operator while entering or exiting the cabin.
Air Conditioned Cabin
The spacious Air Conditioned cabin creates a very comfortable working environment for the operator.
Premium Seat
Hyundai excavators feature deluxe operator's seats with mechanical suspension, selectable heat and adjustable arm rests and control consoles. Seats are fully adjustable for maximum operator comfort.
Digital Cluster with Color Display and Work Mode Selection
The digital cluster displays key machine information like oil temperature, coolant temperature, and other vital statistics. Optimized performance is achieved by letting operator to choose between two power modes, three work modes and two User Modes.
Advanced Audio System
The audio system includes an AM/FM radio, a USB-based MP3 player, an integrated Bluetooth hands-free feature and a built-in microphone to allow for phone calls while at work and in transit. The audio system controls are located on the right side of the operator for convenient access.
