User manual HYUNDAI HL740-7A BROCHURE

[. . . ] Push the lever forward to drive forward, pull it back for reverse. Travelling is automatically changed from 1st stage to given stage according to travel speed and traction effort. 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 Engine control Unit (ECU), Transmission control Unit (TCU) and Machine control Unit (MCU) realize the optimal performance through the mutual CAN communications. MCU Ride control system (option) Ride control is available for smooth travelling. [. . . ] The large access engine-side-panels permit easy and safe inspections. The fuel and oil filters can be spun 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 HL740-7A_new_en 02-11-2007 14:38 Pagina 10 Specification Engine Maker/Model Type CUMMINS QSB6. 7 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 108 kW (145 HP) at 2, 100 rpm 103 kW (138 HP) at 2, 100 rpm 108 kW (146 HP) at 2, 000 rpm 690 Nm (499 lbf. ft) at 1, 400 rpm 6 Alternator Battery Starting motor Cooling 107 mm (4. 2") x 124 mm (4. 88") 6. 7 litres (409 cu in) 17. 2 : 1 Dry, dual elements 24 V - 70 Amp 2 x 12 V - 80 Ah. 24 V - 3. 7 kW Hydraulic remote cooling system 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.
