[. . . ] The sturdy frames, together with the reinforced front/rear frame linkage, resist loading stress and shocks while in operation. Axle Inboard type brake discs. 2 Operating modes: L L Best Economy Mode Maximum fuel efficiency in general loading conditions Maximum Power Mode Maximum power output for driving uphill and hard digging conditions Battery master switch A master switch disconnects the battery power to protect the electrical system from excessive electrical drainage. Sealed loader linkage Fully protected fitting including dust seals and orings on the bucket linkage will extend lubrication intervals remarkably. Frame lock The machine can be locked by a locking bar to prevent movement during transportation. Multi Function Transmission The newly developed transmission control represents the beating heart of transmission. The hydraulically operated gear shifting with proportional valves allows precise clutch operation. For each gear change, the control unit performs a monitoring function to ensure that the specified shift curve is adhered to, and readjusts the shift pressure applied to the clutches accordingly. This result in smooth gearshifts under load without traction interrupts. It also prevents standstills, sudden load changes or torque peaks during operation such as steep hill driving with full load. In addition, there is the option for the driver to make manual gearshifts. 7 HL740-7A_new_en 20-08-2007 14:11 Pagina 8 Accessible and Serviceable New Generation, Innovative Solution in Earth Moving, the HL740-7A 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. I Photo may include optional equipment. 8 HL740-7A_new_en 20-08-2007 14:11 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 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.
