HYUNDAI ROBEX 290LC-7 HIGH CHASSIS CRAWLER EXCAVATOR

Technical Description

The Hyundai ROBEX 290LC-7 High Chassis is a versatile mid-sized crawler excavator engineered for demanding construction and earthmoving applications. Powered by a Cummins QSB5.9-C turbocharged diesel engine, this machine delivers 197 net horsepower at 1,900 rpm with 685 lb-ft of torque, providing robust performance across varied job sites. The high chassis configuration offers enhanced ground clearance of 2.6 feet and improved visibility from the wide cab design, making it suitable for rough terrain operations. Operating at approximately 70,860 pounds, the excavator features a 600mm triple-grouser track system with 48 shoes per side, generating only 8.9 psi ground pressure for minimal site disturbance. The hydraulic system operates at 4,690 psi with 137.4 gpm pump capacity, enabling smooth and precise digging operations across multiple boom and stick configurations. Four distinct working modes accommodate bucket capacities ranging from 1.1 to 2.5 cubic yards, with maximum reach capabilities extending to 36.7 feet depending on attachment selection. The machine excels in vertical digging applications, achieving depths to 25.6 feet with maximum loading heights of 25 feet, while maintaining a compact shipping profile under 35.1 feet length and 12.3 feet height. Advanced features include a Max Flow Cut-off System for precise finishing work, auto-deceleration for fuel efficiency, and a Mode Control System that optimizes engine performance relative to workload demands. The 126.9-gallon fuel capacity supports extended operational periods, while the low-noise design and superior cab visibility enhance operator comfort and productivity on extended shifts.
