The newest scraper in the Cat line, the 611 is fast, quick to load and dump, yielding consistently high productivity at the lowest cost.
Perfectly matched power train - all Caterpillar components work together to deliver responsive power when you need it.
Four-stroke-cycle-design - long, effective power strokes, more complete fuel combustion.
Turbocharged for increased performance and efficiency - especially at high altitudes, up to 1707 meters (5,600 feet).
Realistic Power Rating
Realistic power rating - full rated power available on the job.
40% Torque Rise
High 40% torque rise for superior lugging keeps 611 moving through tough spots without downshifting.
Direct-injection Fuel System
High-pressure, direct-injection fuel system provides excellent fuel atomization for unmatched fuel economy, reliability and durability.
Full-length, water cooled cylinder liners provide maximum heat transfer.
Oil-cooled pistons increase heat dissipation, promote longer piston life.
Oil cooler maintains proper oil temperature, helps cool engine components, prolongs lubricant life.
Resiliently mounted engine reduces noise and vibration for greater operator comfort and productivity.
Torque converter provides excellent rimpull in torque converter drive.
Single-lever, on-the-go shifting for easy selection of the optimum speed range throughout the work cycle.
Six speeds forward and one reverse.
Gears one through six provide automatic torque converter lock-up for maximum haul road speeds and fuel efficiency.
Transmission guard protects the transmission and transfer gears from underside damage.
A suspended axle helps provide a smoother ride for increased production and reliability.
Significantly increases production over rough haul roads by reducing bounce for high speeds.
Two load cylinders attached to the tractor frame and axle, absorb haul road shocks through a nitrogen-over-oil accumulator.
Tag link mounted horizontally between the differential and the tractor frame helps prevent axle sidesway.
Automatic Leveling Valve
Automatic leveling valve provides maximum shock absorption at any scraper load.
Selector lever in the cab locks out the axle suspension for precise loading or dumping.
Valve, Pins, Wear Rings
Maximum 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.
The 611 has an excellent viewing area.
Seat is multi-adjustable with air suspension for shift-long comfort.
Tilt/telescopic steering wheel enhances operational comfort and allows easier entrance and exit.
Modulated, variable-flow steering for precise, low effort maneuverability.
Controls are easy to reach with low operational effort.
Ejector return with detent and automatic kickout allows operator to concentrate on other areas of machine operation.
Sound - 75 dB(A) operator exposure level when equipped with optional cab.
Resiliently mounted engine and cab/canopy minimize vibration of the operator's compartment.
Tilt-out windshield (open ROPS) --additional control of fresh air circulation.
Integral Rollover Protective Structure
Integral 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.
Modeled after the proven 621 Scraper design.
Cutting edges help you match the machine to job requirements.
Reversibility extends the life and lowers your Ground Engaging Tool cost.
Heat-treated and through hardened with minimum Rockwell surface hardness of 45 -- long life before reversal is required.
All scraper ground engaging tools are warranted against breakage.
For optimum productivity, select the thinnest G.E.T. that gives acceptable life.
Ground-level access to majority of daily maintenance areas.
Diagnostic connector allows quick analysis of the starting and charging system.
Wiring - the quality of materials and design is having a greater effect on machine availability.
Outboard, planetary final drives can be removed independently of wheel mounting and brakes.
Hydraulic pressures can be obtained quickly and easily through quick connect/disconnect check points.
Many maintenance points can be easily accessed at ground-level.
Maintenance Platform Access
Maintenance 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 Valves
S-O-S Oil and Sampling Valves provide a fast, convenient means of obtaining fluid samples and improve analysis reliability.
