CONSTRUCTION: EXCAVATORS

HYUNDAI R1200-9 EXCAVATOR for mining and quarrying

U nderlining its intention of competing on a broad front in all sectors of the construction and mining equipment business, Hyundai’s top-end excavator in the 100 t-plus sector endorses the compa- ny’s commitment to large-scale investment in developing new products and new mar- ket opportunities. Building on Hyundai’s experience with the successful 50 t and 80 t high capaci- ty models, the all-new 120 t R1200-9 has been conceived with an eye on the expand- ing worldwide mining and quarrying sector, where the demand for efficient, large-scale mass excavation in minerals extraction and overburden removal has fuelled an increase in sales of large mining trucks and the equipment to load them. The R1200-9 is powered by the high-per- formance 23 litre, 6-cylinder Cummins QSK23-C rated at 760hp (567 kW). Particu- lar attention has been paid to the insulation to achieve low internal and external noise levels.

Special attention has been given to the cab design which allows a clear, open and con- venient interior with excellent visibility, plac- ing the operator in a perfect position to work safely and securely. An advanced 140 mm wide LCD display al- lows the operator to select personal machine preferences and monitor crucial machine data. Power and work mode selection, ma- chine diagnosis, optional rear-view camera, maintenance check lists, start-up machine security and video functions have been in- tegrated into the menu to make the machine more versatile and the operator more pro- ductive. b

back-actor boom, 3.4 m dipper-arm, and 6.7 m³ bucket – a combination which gives a maximum digging depth of nearly 8m, an outreach of 13.76 m, and a load-over height of 7.8 m. Maximum breakout force at the bucket is a massive 64.9 tons – and with three selectable power modes (Power, Speed & Economy), this is clearly a machine designed for extra-heavy digging duties and loading of large capacity dump-trucks. In order to achieve optimum precision, Hyun- dai engineers have designed the R1200-9’s hydraulic system to provide the operator with super fine touch and controllability. Improved pump flow thereby minimises fuel consumption and improved spool valves are engineered to provide more precise flow to each function with less effort. In addition to power and precision, the R1200-9 is robust and durable when taking into account the strengthened undercar- riage, a design that makes for an excellent production rate in quarries and mines. Dura- ble full track rail guards keep track links in place and track adjustments are made easy with standard grease cylinder track adjust- ers and shock absorbing springs.

This version of the new 120 t machine is equipped with a heavy-duty 7.55 m
