    THROTTLE BACK-UP

    Throttle back-up provides the operator with a preset engine speed control in the event of a throttle input failure.

    THROTTLE LOCK

    The throttle lock allows the operator the capability of locking both engines at any operating level.

    DIRECTIONAL SHIFT MANAGEMENT

    Directional shift management prevents the operator from shifting out of neutral when engine rpm is above a preset level.

    CONTROLLED THROTTLE SHIFTING

    Controlled throttle shifting increases drive train life by reducing the fuel injection rate just prior to shifting.

    AUTOMATIC ETHER STARTING AID

    Automatic ether starting aid greatly improves cold weather starting.

    ELECTRONIC GROUND LEVEL SHUTOFF

    Electronic ground level shutoff enables the operator to stop the engine from the ground with the flip of a switch.

    STEEL SPACER PLATE

    Steel spacer plate between the block and head eliminates the need for counterbores and helps prevent associated cracking problems.

    OIL-COOLED PISTONS

    Oil-cooled pistons and full-length water-cooled cylinder liners provide maximum heat transfer for longer component life.

    AFTERCOOLER

    The aftercooler lowers intake charge air temperature to increase power and reduce thermal stresses that can cause premature wear of pistons, rings, and liners.

    ENGINE OIL COOLER

    Engine oil cooler maintains optimum oil temperature for proper cooling and longer lubricant life.

    LAMINATED THERMO-SHIELD

    Laminated thermal-shield improves tractor protection by reducing the temperature of exposed engine surfaces, cools engine and operating compartments, extends hose and wiring life.

    STANDARD HYDRAULIC RETARDER

    An optional hydraulic retarder can extend brake life.

    TRANSMISSION

    Eight-speed power shift transmission provides automatic, on-the-go shifting for simple, reliable operation.

    NEUTRAL COAST INHIBITOR CONTROL

    Neutral coast inhibitor control helps prevent the transmission from shifting to neutral at speeds above 8.1 km/h (5 mph).

    TOP GEAR CONTROL

    Top gear control helps prevent shifting above a programmed gear to better regulate haul road speeds.

    ELECTRONIC PROGRAMMABLE TRANSMISSION CONTROL (EPTC II)

    Electronic Programmable Transmission Control (EPTC II) records both current and intermittent faults.

    ELECTRONICALLY CONTROLLED CUSHION HITCH

    Smoother ride improves productivity.

    DESIGN

    The Caterpillar electronically controlled cushion hitch design dampens shocks to provide a smoother ride.

    NITROGEN ACCUMULATORS

    Nitrogen-over-oil accumulators absorb and dampen road shocks.

    CUSHION HITCH LOCK

    Electronically controlled cushion hitch locks down for positive control of the cutting edge during loading and dumping.

    DOUBLE KINGBOLT DESIGN

    Double kingbolt design withstands high external forces and allows easy installation and removal.

    HITCH CASTINGS

    Extensive use of steel castings eliminates many welded joints, making a strong hitch.

    SCRAPER BOWL

    Low, wide, large-capacity scraper bowl design boosts production and tandem power increases efficiency.

    BOWL

    Caterpillar Coal Scraper bowls come from the factory especially built for coal handling.

    AUGER MECHANISM

    An auger mechanism in the bowl improves self-loading capabilities by lifting material off of the cutting edge and carrying it to the top of the load.

    TANDEM POWER

    A coal-handling scraper has to keep working around the clock, in all kinds of weather and conditions.

    OPERATOR’S STATION

    Comfort and control increase operator efficiency.

    CAB

    Standard rubber-mounted cab reduces noise and vibration for comfortable, shift-long operation.

    CONTROLS

    Low-effort controls are easily accessible for sure, precise operation.

    STEERING

    Hydraulic servo-steering system provides low-effort automotive feel and excellent maneuverability.

    STEERING COLUMN

    Tilt steering column adjusts to five different positions for operator comfort and control.

    SEAT

    A suspension seat delivers a comfortable ride.

    ELECTRONIC MONITORING SYSTEM

    The Electronic Monitoring System checks important machine systems and provides a three-level warning.

    RADIO

    The operator’s station includes radio compatible wires in the cab.

    FEATURES
