User manual HYUNDAI HL757-7A BROCHURE

[. . . ] (Option) Full automatic shift lever A single lever on the left side of the steering column gives the operator fast and easy control of speed and direction. 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. [. . . ] Improved Axle · Limited Slip Defferential in standard eqipment allows easy driving on variable ground condition. · Self adjusting Brake which regulate the Disk clearance automatically can maintain optimum Brake performance. · Due to Improved internal Oil circuit, durabiliy of Axle is increased. 7 HL757-7A_new_en 23-08-2007 09:23 Pagina 8 Accessible and Serviceable New Generation, Innovative Solution in Earth Moving, the HL757-7A Accessible grease fittings Grease fittings are highlighted and centralized on the machine for fast access when doing your service checks. Simple air filter replacements The air cleaner is easily replaceable by turning the wing nut on the outer shell counter-clockwise. Open pin access You can quicker remove or tighten your front attachment pin (chromated) with this open connector system. Remote type drain port It is now easier to change your engine oil, coolant and hydraulic oil with the remote drain port located near the rear axle of the machine. 8 HL757-7A_new_en 23-08-2007 09:23 Pagina 9 An ideal arrangement of components ensures easy access and convenience for maintenance. A highly accessible engine compartment assures fast and efficient maintenance. Hydraulic tank The hydraulic tank is located behind the cab to facilitate accessibility of hydraulic hoses and piping. Oil sight gauge A sight gauge is installed on the side of the hydraulic tank for convenient ground level check out. Transmission oil port The transmission oil change port is openly accessible. It comes with an anti-vandalism lock for machine protection. Centralised electric controllers & Fuse Box The electric controllers for this loader are centralized together with the fuse box to improve serviceability and facilitate inspections. Cabin Air Fresh Filter The internal pressure is maintained slightly higher than that of outside to exclude dust from and reduce noise level in the cabin. Coolant Sight Gauge A sight gauge is installed on top of the radiator tank for convenient checks of the coolant level. Easy Access to All Engine Components Here you find engine oil check and main and pre-filters. 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 installed. 9 HL757-7A_new_en 02-11-2007 15:30 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 129 kW (173 HP) at 2, 100 rpm 122 kW (164 HP) at 2, 100 rpm 133 kW (187 HP) at 1, 800 rpm 830 Nm (600 lbf. ft) at 1, 400 rpm 6 Alternator Battery Starting motor 107 mm (4. 2") x 124 mm (4. 88") 6. 7 litres (409 cu in) 17. 2 : 1 Dry, dual elements 24V, 70 Amp 2 x 12V, 130 Ah. 24V, 3. 7 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.
