Perfectly matched power train - all Caterpillar components work together to deliver responsive power when you need it.
Four-Stroke-Cycle DesignFour-stroke-cycle-design - long, effective power strokes, more complete fuel combustion.
TurbochargedTurbocharged for increased performance and efficiency - especially at high altitudes, up to 1707 meters (5,600 feet).
Realistic Power RatingRealistic power rating - full rated power available on the job.
40% Torque RiseHigh 40% torque rise for superior lugging keeps 611 moving through tough spots without downshifting.
Direct-injection Fuel SystemHigh-pressure, direct-injection fuel system provides excellent fuel atomization for unmatched fuel economy, reliability and durability.
Cylinder LinersFull-length, water cooled cylinder liners provide maximum heat transfer.
PistonsOil-cooled pistons increase heat dissipation, promote longer piston life.
Oil CoolerOil cooler maintains proper oil temperature, helps cool engine components, prolongs lubricant life.
Engine MountingResiliently mounted engine reduces noise and vibration for greater operator comfort and productivity.
Torque ConverterTorque converter provides excellent rimpull in torque converter drive.
On-the-go-ShiftingSingle-lever, on-the-go shifting for easy selection of the optimum speed range throughout the work cycle.
Six SpeedsSix speeds forward and one reverse.
GearsGears one through six provide automatic torque converter lock-up for maximum haul road speeds and fuel efficiency.
Transmission GuardTransmission guard protects the transmission and transfer gears from underside damage.
A suspended axle helps provide a smoother ride for increased production and reliability.
Increased ProductionSignificantly increases production over rough haul roads by reducing bounce for high speeds.
Load CylindersTwo load cylinders attached to the tractor frame and axle, absorb haul road shocks through a nitrogen-over-oil accumulator.
Tag LinkTag link mounted horizontally between the differential and the tractor frame helps prevent axle sidesway.
Automatic Leveling ValveAutomatic leveling valve provides maximum shock absorption at any scraper load.
Selector LeverSelector lever in the cab locks out the axle suspension for precise loading or dumping.
Valve, Pins, Wear RingsMaximum reliability with improved selector valve, suspension cylinder pins, charging valve, accumulator piston and wear rings.
Convenient control placement and a comfortable work environment are keys to high productivity.
ViewingThe 611 has an excellent viewing area.
SeatSeat is multi-adjustable with air suspension for shift-long comfort.
Steering WheelTilt/telescopic steering wheel enhances operational comfort and allows easier entrance and exit.
SteeringModulated, variable-flow steering for precise, low effort maneuverability.
ControlsControls are easy to reach with low operational effort.
Ejector ReturnEjector return with detent and automatic kickout allows operator to concentrate on other areas of machine operation.
SoundSound - 75 dB(A) operator exposure level when equipped with optional cab.
VibrationResiliently mounted engine and cab/canopy minimize vibration of the operator's compartment.
WindshieldTilt-out windshield (open ROPS) --additional control of fresh air circulation.
Integral Rollover Protective StructureIntegral Rollover Protective Structure (ROPS) - Canopy is included in the standard arrangement, and the cab is optional.
Electronic Monitoring System (EMS)The Electronic Monitoring System (EMS)- three stages of alert notify the operator of varying degrees of required action to avoid possible damage or failure to components/systems.
The 611 was developed to be push loaded by the D6R Track-Type Tractor.
Scraper BowlModeled after the proven 621 Scraper design.
Cutting edges help you match the machine to job requirements.
ReversibilityReversibility extends the life and lowers your Ground Engaging Tool cost.
Heat-treatedHeat-treated and through hardened with minimum Rockwell surface hardness of 45 -- long life before reversal is required.
WarrantedAll scraper ground engaging tools are warranted against breakage.
ProductivityFor optimum productivity, select the thinnest G.E.T. that gives acceptable life.
Ground-level access to majority of daily maintenance areas.
Diagnostic ConnectorDiagnostic connector allows quick analysis of the starting and charging system.
WiringWiring - the quality of materials and design is having a greater effect on machine availability.
Final DrivesOutboard, planetary final drives can be removed independently of wheel mounting and brakes.
Check PointsHydraulic pressures can be obtained quickly and easily through quick connect/disconnect check points.
Ground-level AccessMany maintenance points can be easily accessed at ground-level.
Maintenance Platform AccessMaintenance platform access - engine oil check and fill, engine coolant level check and fill, front brake reservoir, hydraulic system filter, secondary fuel filter.
S-O-S Oil and Sampling ValvesS-O-S Oil and Sampling Valves provide a fast, convenient means of obtaining fluid samples and improve analysis reliability.
