The R1200-9 boasts a dig depth of 26 ft. 3 in. (8 m) a bucket digging force of 125,540 lbs. (115,080 kg) and bucket capacity of 8.76 cu. yds. (6.7 cu m).
Hyundai Construction Equipment Americas Inc.’s largest excavator — the R1200-9 — is new to the North American market and is designed for the mining and quarrying sector.
The R1200-9 has an operating weight of 260,140 lbs. (118,000 kg) and is powered by a 740 hp (552 kW) Cummins QSK23-C engine. The engine is electronically controlled for optimum fuel to air ratio and clean, efficient combustion. Auto engine overheat and anti-restart features also are provided. The R1200-9 boasts a dig depth of 26 ft. 3 in. (8 m) a bucket digging force of 125,540 lbs. (115,080 kg) and bucket capacity of 8.76 cu. yds. (6.7 cu m).
To achieve optimum precision, Hyundai redesigned the R1200-9’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 auto boom-swing priority function makes for optimal performance in any application.
In addition to power and precision, the R1200-9 also is durable. A strengthened undercarriage is designed for production at quarries and mines and is equipped with covers to protect the travel motors and hoses against damage from rocks. Durable full track rail guards keep track links in place and track adjustment is made easy with standard grease cylinder track adjusters and shock absorbing springs. Structure strength on the R1200-9 also 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.
Hyundai kept operator comfort a top priority with the R1200-9 excavator. Operators can fully customize their work environment and operating preferences to fit their individual needs. A newly designed cabin with single piece right side glass was 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.
A 7 in. 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.
