User manual HYUNDAI HL770-7A BROCHURE

[. . . ] The operator can select two kinds of automatic modes (1st <-> 4th, 2nd <-> 4th). This exclusive feature contributes to a step-up in productivity and reduction of operator's fatigue. Up-to-Date-technology CAN System ECU TCU MCU Engine control Unit (ECU), Transmission control Unit (TCU) and Machine control Unit (MCU) realize the optimal performance through the mutual CAN communications. Ride control system A ride control system is available for smooth travelling during load and carry operation. It significantly reduces machine bouncing and absorbs shocks while travelling so enhancing productivity. This system reduces operator's fatigue as well as stress on the structure and components of the machine. 5 HL770-7A_new_en 21-08-2007 08:50 Pagina 6 I Photo may include optional equipment. New Generation, Innovative Solution in Earth Moving, the HL770-7A QSL Engine CUMMINS The CUMMINS QSL electronic control engine combines full authority electronic controls with the reliable performance. [. . . ] The filters can be screwed on and off for quick replacements. Up-to-date hydraulic remote cooling fan Minimum fuel consumption and low noise is realized by using a hydraulic cooling fan sensing coolant temperature, intake air temperature, transmission oil temperature and hydraulic oil temperature. Reversible cooling fan is installed. 9 HL770-7A_new_en 05-11-2007 16:34 Pagina 10 Specification Engine Maker/Model Type CUMMINS QSL 4-cycle, turbocharged, charge air-cooled direct injection, electronic controlled diesel engine Bore x Stroke Displacement Compression ratio Air cleaner Gross power Net power Maximum power Maximum torque No. of cylinders 209 kW (280 HP) at 2, 000 rpm 198 kW (266 HP) at 2, 000 rpm 231 kW (310 HP) at 1, 700 rpm 1, 480 Nm (1, 070 lbf. ft) at 1, 400 rpm 6 Alternator Battery Starting motor 114 mm (4. 5") x 145 mm (5. 7") 8. 9 litre (543 cu in) 17. 8 : 1 Dry, dual elements 24 V, 70 Amp 2 x 12 V, 160 Ah. 24 V, 7. 5 kW * Net power output of standard engine as installed in this vehicle(per SAE J1349) complete with fan, air cleaner, alternator, water pump, lubricating oil pump and fuel pump.
