Two Speed Ranges

The machine operates at either maximum torque throughout the entire milling speed range or at a faster travel speed for moving around the job site.

Positive Traction Control (Flow Divider)

Equal hydraulic oil flow to each drive motor increases tractive effort in hard cutting applications. The positive traction control is actuated from the operator’s console.

Polyurethane Track Pads

Track pads in polyurethane provide long service life and positive traction on all pavement surfaces.

Mechanical Dry Clutch

The rotor drive consists of trapezoid pulleys, molded high-strength belt and a hydrauliccoupling dry clutch. The field-proven drive system delivers reliability and long service life.

Drive Train Protection

A drive train protection device protects rotor drive system, rotor and tools by instantly disengaging rotor drive whenever an abrupt drop in rotor rpm occurs.

Two Cutting Speeds

Upper and lower sheaves are easily interchangeable for maximum torque with the toughest materials and different material sizing requirements.

Molded Six-Rib High Tensile Belt

High tensile belt provides efficient transmission and long service life.

Automatic Belt Tension Adjustment

The hydraulically powered automatic drive belt tensioner prevents rotor drive belt slippage and reduces maintenance.

98 Carbide-Tipped Tools

Tools are mounted in durable three-piece, quick release patented tool holders and arranged in a triple wrap flighting pattern for maximum breakout force.

Quick Release Conical Tool Holders

A tapered fit maintains tightness in holder base. Fast and effortless tool removal is provided by the quick release conical tool holder tool removing system.

Large Replaceable Carbide Faced Loading Paddles

Loading paddles effectively move milled material onto collecting conveyor resulting in higher production and less wear on inside of rotor chamber and cutting tools.

Optimum Tool Spacing

Triple-tree tool placement on rotor ends provides optimum tool spacing to clean up loose material and reduces wear on drum when maneuvering in the cut.

Optimum Material Sizing and Gradation

The hydraulically operated anti-slab device prevents slabbing of the road surface, protects the collecting conveyor and ensures an optimum discharge opening to the rotor chamber.

Maximum Efficiency

The collecting conveyor's width measures in at 550 mm (21.6") and is driven by a high torque hydraulic motor for maximum efficiency.

Variable Belt Speed

The collecting conveyor features variable belt speed for optimum production in all applications. Reversible belt rotation control is also provided.

Optimum Dust Reduction

Standard pressurized water spray lubricates and controls dust on collecting belt. Water spray nozzles are easily removed for inspection and replacement without the need for tools.

Folding Conveyor

Machine transportation is made easier by the folding front conveyor that reduces the machine dimensions.

Hydrualically Controlled Height Adjustment

The upper conveyor's width measures in at 600 mm (23.6") and its height adjustment is hydraulically controlled while two cylinders provide a 41 degree swing to the left and right.

Variable Loading Belt Speed and Reversible Rotation

The front loading conveyor also includes variable belt speed and reversible belt rotation control. The loading belt speed is infinitely variable and provides optimum discharge capability for uniformly loading the haul truck.

Simplified Conveyor Removal

Quick-fitting hydraulics and mechanical conveyor components allow the front conveyor to be easily detached from the machine.

Ergonomic Operator's Station

The full width operator’s station provides a view of the front loading conveyor and side plates for precise and rapid positioning.

Suspension Seat

Durable suspension seat with armrest provides optimum operator comfort.

Warning Horns and Shut Down Buttons

Located on the operator’s station and at ground level control stations.

Hydrualically Operated Canopy Option

Full width canopy with two extending side wings and front windshield and rear window provides optimum operator comfort and protection. Canopy can be hydraulically lowered during transportation.

Operating Controls

The distribution and clear instrumentation layout on the front and side control consoles have been designed to ensure minimum operator effort and maximum automation. All gauges and displays are easily visible even in direct sunlight.

Graphic Disply

A large display, easily visible in direct sunlight, provides operating parameters for machine and engine diagnostics. The display presents a single interface for service diagnostics and calibration.

Computerized Monitoring System (CMS)

The system constantly monitors system pressures and engine condition with multiple modes of operation. Alerts the operator if a problem does occur with three levels of event information.

Standby Control

A single switch control allows the operator to engage or disengage main operating functions including propel, water spray system, leveling system and conveyor rotation for maximum automation.

Flush Cutting

The right rear leg can be swung in within the machine’s cutting width for full flush cutting applications. With the right rear leg swung in, the machine can cut close to a wall, barrier or other vertical obstruction.

Exclusive Caterpillar Single-Peice Swing-Arm Design

The swing-in arm mechanism ensures increased rigidity eliminating excessive wear for increased component life.

Automatic Control

The rear leg swing-in system is automatic and controlled from the operator’s station. The operator is not required to leave the seat while positioning the right rear leg within the machine’s cutting width.

Precise Control

A microprocessor electronically controls the steering angle of the right rear track. The rear track steering angle is automatically adjusted in relation to the position of the front tracks.

Enhanced Steering Ability

The machine's rear track steering feature facilitates operation in confined areas and ensures a close cut around cul-de-sacs or turns. The right rear track steers in both positions, whether positioned within or outside the cutting width.

Contacting Wire Rope Grade Sensors

Wire rope grade sensor measures side plate movement that enables the entire length of the side plate to become an averaging device for extremely accurate grade matching. Cross slope sensor adds to system versatility.

Leveling Control Boxes

Two control boxes located at the operator’s station allow manual or automatic leveling adjustment. Constant read-out for rotor depth and cross slope are displayed on each control box and is easily visible even in direct sunlight or low light conditions.

Large Service Doors

Large service doors provide access to engine and hydraulic components. Engine side covers swing wide to allow ground level access to engine. Rear cover swings up for access to radiator and oil cooler.

Hydrualic Rotor Service Door

The rotor service door opens wide for easy access to rotor for inspection and tool maintenance.

Electronic Control Module (ECM)

The ECM monitors machine systems and provides self-diagnostics for operator or service personnel.

All-Weather Connectors

Nylon braided wrap ensure electrical system integrity.

Visual Indicators

Visual indicators allow easy check of water spray tank level and hydraulic oil tank level.
