The all-new, deluxe operating space is engineered with 3-D modeling for your ultimatecontrol center. The wide, tinted and laminated front windshield has no framing cuttingthrough to ensure excellent visibility.

Ride control system (Option)

Ride control system functions such as shock absorbers gives smoothoperation without losing of the load even over a rough terrain condition.Therefore the system allows faster travelling and improved safety andproductivity.

The operator can easily control thetemperature and air flow . The defroster onthe front windshield and rear window makesit convenient for winter working usage.

A single lever on the left side of thesteering column gives the operator fast,easy control of speed and direction.Push the lever forward to go forward,pull it back for reverse. Travelling isautomatically changed from 1st stageto given stage according to travelspeed and tractive effort. The operatorcan select two kinds of automaticmodes (1st 4th, 2nd 4th). These exclusive features contribute toa step-up in productivity and reductionof operator’s fatigue.

New Generation, Innovative Solution in Construction HL780-7A

The CUMMINS QSM11 electronic control enginecombines full-authority electronic controls withthe reliable performance. The combination of improved airflow and evenlydispersed fuel results in increased power,improved transient response and reduced fuelconsumption. And the QSM11 uses advancedelectronic controls to meet the emissionstandards. (EPA Tier-3, EU StageIII-A)

CUMMINSQSM11 Engine

Multi Function Transmission

The newly developed transmission control represents the beating heart of transmission. The hydraulicsystem for gearshifts is working with proportional valves, which allow very precise control of the clutches.For each gearchange, the control unit performs a monitoring function to ensure that the specified shiftcurve is adhered to the range, and readjusts the shift pressure applied to the clutches accordingly. Thisresults in smooth gearshifts-even under the load-with no traction interruptions. This helps to avoidstandstill of the vehicle, sudden load changes and torque peaks under all conditions, for exampleapplication on steep terrain with full load. In addition, there is the option for the driver to make gearshiftsmanually.

The minimum fuel consumption andlow noise is realized by applyinghydraulic cooling fan that sensescoolant temperature, intake airtemperature, transmission oiltemperature and hydraulic oiltemperature.

Accessible and Serviceable

Accessible grease fittingsGrease fittings are highlighted andavailable around the machine forthe fast access when doing yourservice checks.

Simple air filter replacementsThe air cleaner is easilyreplaceable by turning the wingnut on the outer shellcounterclockwise.

Chromium - Plated PIN is appliedWith the application of ChromiumPlated PIN whose durability andprecision are improved and the lifecycle became longer.

Remote type drain portIt is now easier to change yourengine oil, coolant and hydraulicoil with the remote drain port.

Hydraulic tankThe hydraulic tank is located behind the cab to increase theaccessibility of hydraulic hoses and pipings.

Oil sight gaugeThe hydraulic oil check sightgauge is installed on the side of thehydraulic tank for the convenientchecks from on the ground level.

Transmission oil portThe transmission oil change port isalso located for with openaccessibility and comes with ananti-vandalism lock for yourmachine protection.

Easy Access to AllEngine Accessaries

Here you find the engine oilcheck, and the main and pre-filters. The large accessengine-side-panels permit easyand safe inspections. The fuelfilter can be spun on and off forquick replacements.

An ideal arrangement of component parts ensures easy access and convenience for maintenance.Highly accessible engine compartment assures fast and efficient maintenance.
