New Wheeled Excavators from Hyundai
Hyundai Construction Equipment is introducing three new wheeled excavator models, the R140W-9A, R180W-9A and the R210W-9A, to their 9A series product line.
These machines offer certified Tier 4 interim engine upgrade, improved hydraulics, increased operator comfort and added durability. These are mid-size excavators providing power and mobility for excavating projects, road and utility work and demolition. The R140W-9A, R180W-9A and R210W-9A have operating weights of 30,200 lbs (13,700 kg), 38,100 lbs (17,280 kg) and 45,200 lbs (20,500 kg), respectively. Each is powered with a low emission, low noise, Cummins QSB6.7 Interim Tier 4/Stage IIIB engines with electronically controlled fuel injection and diagnostic capabilities. Other innovations such as the variable speed fan clutch, two-stage auto decel system and the economy mode help to conserve fuel and reduce environmental impact. Plus, operators can choose between three unique engine modes - Power, Standard and Economy- which enable the machine to switch between full power and reduced fuel consumption according to the user’s preference.
Hyundai redesigned the hydraulic system to provide the operator with fine touch and controllability. Improved pump flow control 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. An auto cruise control system reduces operator fatigue. A new auto ram lock system is available to improve operating safety by locking or releasing the ram cylinder according to the operating mode. Cab amenities include heated seats, additional space, enhanced climate control system for optimum air temperature, an advanced audio system with USB player, AM/FM stereo, and MP3 capabilities. A Smart Key System is an optional add on feature that allows the operator to start the ignition with the push of a button.
