Technology in Cab Design

Operator’s Comfort is Foremost.Wide Cab Exceeds Industry Standards.

Visibility!Even more visibility than before, for safer, more efficient operating.

Excellent Ventilation!Ventilation has been improved by the addition of the larger fresh air intake system,

and by providing additional air flow throughout the cab.

!Sliding front and side windows provide improved ventilation.

!A large sunroof offers upward visibility and additional ventilation.

Comfortable Operator Environment!The control levers and seat can be adjusted to provide maximum operator comfort.

!The seat is fully adjustable for optimum operating position, reducing operator

fatigue.

!Console boxes slide forward and backward for improved accessibility.

!The proportional pressure controls reduce unnecessary exertion while ensuring

precise operation.

!Large windows allow excellent visibility in all directions.

Low noise design!The Robex 7series was designed with low operation noise in mind.

!Hyundai engineering helps to keep interior and exterior noise levels to a minimum.

!The cab's noise levels have been additionally reduced by improving the door seals

for the cab and engine compartments.

!An insulated diesel engine compartment with sound-damping material also reduces

noise.

CUMMINS C8.3-C EngineThe six cylinders, turbo-charged, 4 cycle,Charger air cooled engine is built for power,reliability, economy and low emissions.This engine meets Tier!emissions regulations.

Go Confidently Toward Your Dream.Toughness. Determination. Perseverance.Vision. Qualities you’ll find in Cummins C8.3-C.An engine design so advanced, it doesn’tneed electronic engine controls in order tomeet emissions regulations now and in thefuture.The C8.3-C from Cummins will do more thanjust power your equipment.It will power you to your dreams. And we’vegot the performance to prove it.When the C Series was introduced over adecade ago, it redefined what a diesel shouldbe, with 40% fewer parts for greaterreliability and durability.Integrated water and oil pump connectionsfor reduced leaks and maintenance. Anexceptional power-to-weight ratio. And thelowest repair times in the industry.Over the years, in a wide variety of equipmentall over the world, the C8.3-C has helped over500,000 people and companies achieve thesuccess they’ve dreamed about. Now, it’s your turn.

ADVANCED CAPO SYSTEM

Advanced CAPO SystemThe Advanced CAPO(Computer Aided PowerOptimization) system maintains engine andmutual pump power at optimum levels. Modeselections are designed for various work loadsand maintaining high performance whilereducing fuel consumption. Features such as auto deceleration and powerboost are included in the system. The system monitors engine speed, coolanttemperature, and hydraulic oil temperature.Contained within the system are selfdiagnostic capabilities which are displayed byerror codes on the cluster.

Self Diagnosis SystemThe CPU controller diagnoses problems in theCAPO system caused by electric and hydraulicmalfunctions and displays them on the LCDmonitor of the cluster by error codes. Thiscontroller has the capacity to identify 48distinct types of errors. As the informationfrom this device, such as engine rpm, mainpump delivery pressure, battery voltage, hyd.temperature, and the state of all types ofelectric switches, provides the operator with amuch more exact state of machine operatingcondition. This makes the machine easier totroubleshoot when anything does go wrong.

Arm Flow Regeneration SystemArm flow regeneration valve provides smootharm-in operation without cavitation.

Boom & Arm Holding System The Holding valves in the main control valveprevents the boom & arm from dropping overan extended period in neutral position.

Auto Deceleration SystemWhen remote-control valves are in neutralposition more than 4 seconds, CPU controllerreduces engine speed to 1200rpm. This decreases fuel consumption and reducedcab noise levels.

One Touch Decel SystemWhen the one touch decel switch is pressed,CPU controller controls the accel actuator toreduce engine speed to low idle rpm. And thenthe one touch decel switch is pressed again,the engine speed recovers.

Max. Flow Cut-off SystemFor precise control and finishing work, theMax. Flow Cut-off System reduces pump flow,thus allowing smooth operation.

Automatic Engine Overheat PreventionIf the engine coolant temperature gets toohigh, the CPU controller lowers the enginespeed and cools the engine.

Anti Restart SystemThe new system protects the starter fromrestarting during engine operation, even if theoperator accidentally turns the start key again.

Power boost control SystemWhen the power boost system is activated,digging power increases about 10%. It isespecially useful when extra power istemporarily needed, for instance, whendigging hard earth and rock, or if the bucketteeth are stopped by a stubborn tree root.

Automatic Warming-up SystemAfter the engine is started, if the enginecoolant temperature is low, the CPU controllerincreases the engine speed and automaticallyto warm up the engine more effectively.

Pump Flow Control SystemIn neutral position: Pump flow is reduced to aminimum to eliminate power loss. In operation: Maximum pump flow is deliveredto the actuator to increase the speed. Withmovement of the control lever, pump flow isautomatically adjusted and the actuator speedcan be proportionally controlled.

Hydraulic Damper in Travel PedalImproved travel controllability & feeling byshock reducing when starting and stopping.
