Hyundai Construction Equipment has recently displayed their R180W-9A wheeled excavator at ConExpo. This fuel efficient, fast, smooth and easy to control machine provides operators with many improvements from previous models including a Tier 4 Interim engine upgrade. The R180W-9A is ideal for construction and utility projects that require travel such as road and highway demolition and repair.
The R180W-9A has an operating weight of 38,100 lbs (17,280 kg) and is powered by a reliable, fuel efficient 155 hp (115 kW) Cummins QSB6.7 Tier 4 Interim & EU Stage III B engine. Electronically controlled fuel injection and diagnostic capabilities add to the engine’s efficiency and serviceability. The R180W-9A boasts a dig depth of 19’5” (5,900 mm) a bucket digging force of 26,330 lbs (24,250 kg) and bucket capacity of .99 cubic yards (.76 m3).
Hyundai’s R180W-9A wheeled excavator offers an optional fully independent outrigger system for added stability. This model can be equipped with four independent outriggers (front and rear) or two independent outriggers (front or rear). A rear dozer blade comes standard. The outriggers and the dozer blade are controlled by a switch and the dozer lever.
The R180W-9A features a hydraulically actuated, orbital type steering system. Standard tires on this model are 10.00-20-14PR, Dual (Tube Type). Two arm configurations are available on the R180W-9A, a 17’1” mono boom or 17’1” hydraulic adjustable boom.
To achieve optimum precision, Hyundai redesigned the R180W-9A’s hydraulic system to provide the operator with super fine touch and controllability. Improved pump flow minimizes fuel consumption and improved spool valves are engineered to provide more precise flow to each function with less effort. Enhanced hydraulic valves, precision-designed variable volume piston pumps, fine-touch pilot controls and enhanced travel functions make for smooth and easy operation. Arm-in and boom-down flow regeneration and control valve technology are newly improved as well. An innovative auto boom-swing priority function makes for optimal performance in any application.
The R180W-9A was designed for maximum performance with a new and improved travel system. An auto cruise control system is provided to reduce operator fatigue by maintaining a fixed speed when driving distances. A new auto ram lock system is available to improve operating safety and a new creep speed travel system improves maneuverability and fine control. Additionally, a new optional forward/reverse travel pedal control allows operators to choose between using the travel pedal control while in work mode or lever control when in travel mode.
In addition to power and precision, the R180W-9A is also durable. Structure strength has been improved with stronger but slimmer tubing for added safety and better visibility. Low stress, high strength steel is integrally welded to form a stronger, more durable upper and lower frame.
Structural integrity has been tested by the Finite Elements Method (FEM) analysis and long-term durability tests.
As always, Hyundai kept operator comfort a top priority with the R180W-9A excavator. Operators can fully customize their work environment and operating preferences to fit their individual needs. A newly designed cabin has been built for more space and a wider field view. Special attention was given to providing a clear, open and convenient interior with plenty of visibility of the machine surroundings and the job at hand, putting the operator in perfect position to work safely and securely. A fully adjustable seat, console and armrest are provided to best suit the preferred operating position. Other preference settings that add to overall operator comfort include a fully automatic high capacity air conditioning system, transparent polycarbonate glass sun roof, large and easy to control sun visor and radio/USB player.
An advanced 7 inch wide LCD display allows the operator to select personal machine preferences and monitor crucial machine data. Power and work mode selection, self-diagnostics, optional rear-view camera, maintenance check lists, start-up machine security and video functions were integrated into the cluster to make the machine more versatile and the operator more productive. An optional smart key system allows the operator to start the engine at the push of a single button.
Searching for the best-performing excavator? Your search ends here. We tested the Volvo EC350E and EC380E against a leading competitor in three different tests: trenching, truck loading and lifting capacity at reach. The results show a 20% difference in cost-per-ton, a 15% difference in tons-per-hour and a 12% difference in both operating costs and lifting capacity.
