R235LCR-9 Hyundai excavator specs & Dimensions (2019 - 2026)

Excellent Performance in Confined Areas

R235LCR-9’s short (1,680mm) tail swing radius allows the operator work in confined areas like close to buildings on roadways, and in urban areas. This Compact radius design provides easy and efficient operation in any limited space work environment.

Engine Technology

Proven and reliable, fuel efficient HYUNDAI HE6.7 engine. Electronically controlled for optimum fuel-to-air ratio and clean, efficient combustion. Low noise / Auto engine warm up feature / Anti-restart feature.

Eco-friendly HYUNDAI HE 6.7 Engine

HYUNDAI HE 6.7 engine combines advanced electronic controls and a self-diagnostic system with reliable performance. The combination of a high pressure common rail system and an advanced in-cylinder combustion technology results in increased power, improved transient response and reduced fuel consumption. HYUNDAI HE 6.7 engine complies with current emissions standards including EPA Tier3 and EU Stage III-A.

The Definition of Progress

HYUNDAI HE 6.7 engine combines full authority electronic controls with the reliable performance. The machines with the HYUNDAI HE 6.7 have been proven with their high-power productivity in the harshest, most demanding environments-such as dusty, non-stop mining operations where meeting emissions regulations worldwide presents a challenge. It features an advanced fuel system with electronic injectors and symmetrical piston bowl. The combination of improved air flow and efficient combustion 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 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 system 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 4 solenoid v/v, 1 E/PPR valve, 1 check valve, accumulator and line filter controls safety lock, power boost, 2 speed travel, arm-in regeneration, boom priority.

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 functions 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 9S Series.

Long-Life Components

9S 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.

Structural 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 ROPS (Roll Over Protective Structure) cab can be equipped to enhance operator safety.

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, 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 puts 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.
