R290LC-9 Hyundai excavator specs & Dimensions (2019 - 2026)

Improved Cab Construction

New steel tube construction for added operator safety, protection and durability. New window open/close mechanism designed with sliding cable spring lift assist and single latch release.

Engine Technology

Proven, reliable, fuel efficient HYUNDAI HE 6.7 engine. Electronically controlled for optimum fuel to air ratio and clean, efficient combustion. Low noise, low engine warm up feature, anti-restart feature.

Hyundai HE 6.7 Engine

The Tier III compliant, six cylinder, turbo-charged, 4 cycle, water cooled, HYUNDAI HE 6.7 diesel engine is built for power, reliability, efficiency and reduced emissions.

Heavy-duty Strength

HYUNDAI HE 6.7 engine combines full-authority electronic controls with reliable performance. HYUNDAI HE 6.7 engine electronics have been used in our high-horsepower products in the harshest, most demanding environments, including dusty, nonstop mining operations, and meet worldwide emissions regulations. HYUNDAI HE 6.7 engine features 24-valves designed with centered injectors and a symmetrical piston bowl. The combination of improved airflow and evenly dispersed fuel results in increased power, improved transient response, and reduced fuel consumption.

Fuel Efficiency

9 series excavators are engineered to be extremely fuel efficient. New innovations like the variable speed fan clutch, two-stage auto decel system and the new economy mode help to conserve fuel and reduce the impact on the environment.

Hydraulic System Improvements

New patented hydraulic control for improved controllability. Improved control valve design for added efficiency and smoother operation. New auto boom and swing priority system for optimum speed. New auto power boost feature for additional power when needed. Improved arm and boom-down flow regeneration for added speed and efficiency.

Pump Compartment

Industry-leading, powerful, reliable Kawasaki designed, variable volume in-line axial piston pumps. New compact solenoid block equipped with all solenoid valves, 1 EPR valve, 1 check valve accumulator and pilot filter - controls 2 speed travel, power boost, boom priority, safety lock.

Improved Hydraulic System

To achieve optimum precision, Hyundai redesigned the hydraulic system to provide the operator with super fine touch and improved controllability. Improved pump flow control reduces flow when controls are not being used to minimize fuel consumption. Improved spool valves in the control valve are engineered to provide more precise flow to each function with less effort. Improved hydraulic valves, precision-designed variable volume piston pumps, fine-touch pilot controls, and enhanced travel functions make any operator running a 9 series look like a smooth operator. Newly improved features include arm-in and boom-down flow regeneration, improved control valve technology and innovative auto boom and swing priority for optimal performance in any application.

Auto Boom-swing Priority

This smart function automatically and continuously looks for the ideal hydraulic flow balance for the boom and swing motions of the machine. The advanced CAPO system monitors the hydraulic system and adjusts its settings to maximize performance and productivity.

Easy Access

Ground-line access to filters, lube fittings, fuses, machine computer components and wide open compartments makes service more convenient on the 9 series.

Long-Life Components

9 series excavators were designed with bushings designed for long-life lube intervals (250 hrs) & polymer shims (wear resistant, noise reducing), long-life hydraulic filters (1,000hrs), long-life hydraulic oil (5,000hrs), more efficient cooling systems and integrated preheating systems which extend service intervals, minimize operating costs and reduce machine down time.

Structure Strength

The 9 series cabin structure has been fitted with stronger but slimmer tubing for more safety and improved visibility. Low-stress, high strength steel is integrally welded to form a stronger, more durable upper and lower frame. Structural integrity was tested by way of FEM (Finite Elements Method) analysis and long-term durability tests. The optional ROPS (Roll Over Protective Structure) cab can be equipped to enhance operator safety.

Enhanced Operator Cab

Improved Visibility. Enlarged cab with improved visibility. See-through upper skylight for visibility and ventilation. Larger right-side glass, now one piece, for better right visibility. Safety glass windows on all sides - less expensive than polycarbonate and won't scratch or fade. Closeable sunshade for operator convenience. Reduced front window seam for improved operator view.

Improved Suspension Seat / Console Assembly

Ergonomic joysticks with auxiliary control buttons for attachment use. Now with new sleek styling. Heated suspension seat standard or optional air ride suspension seat with heater. New joystick consoles - now adjustable in height by way of dial at bottom. Adjustable arm rests - turn dial to raise or lower for optimum comfort.

Reduced Stress

Work is stressful enough. Your work environment should be stress free. Hyundai's 9 series provides improved cab amenities, additional space and a comfortable seat to minimize stress to the operator. A powerful climate control system provides the operator with optimum air temperature. An advanced audio system with USB player, AM/FM stereo and MP3 capabilities, plus remotely located controls is perfect for listening to music favorites. Operators can even talk on the phone with the hands-free cell phone feature.

Wide Cabin with Excellent Visibility

The newly designed cabin was conceived for more space, a wider field of view and operator comfort. Special attention was given to a clear, open and convenient interior with plenty of visibility on the machine surroundings and the job at hand. This well balanced combination of precision aspects put the operator in the perfect position to work safely and securely.

Undercarriage

Sealed track chain (urethane seals). Standard track rail guard. Comfortable bolt-on steps. Large upper roller cut-outs for debris clean-out. Tapered side frames for debris clean-out. Grease-type track tensioner.

Track Rail Guard & Adjusters

Durable track rail guards keep track links in place. Track adjustment is made easy with standard grease cylinder track adjusters and shock absorbing springs.
