Large Replaceable Carbide Faced Loading PaddlesLoading 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 SpacingTriple-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.
Primary Collecting Conveyor
The collecting conveyor belt efficiently clears out the cutter box fast. Water spray system for lubrication, cooling and dust reduction.
Optimum Material Sizing and GradationThe 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 EfficiencyThe 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 SpeedThe collecting conveyor features variable belt speed for optimum production in all applications. Reversible belt rotation control is also provided.
Optimum Dust ReductionStandard 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 Front Loading Conveyor
High capacity and versatility add to increased job site productivity. Conveyor can be folded to reduce machine dimensions during transport.
Folding ConveyorMachine transportation is made easier by the folding front conveyor that reduces the machine dimensions.
Hydrualically Controlled Height AdjustmentThe 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 RotationThe 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 RemovalQuick-fitting hydraulics and mechanical conveyor components allow the front conveyor to be easily detached from the machine.
Designed for efficiency, productivity and simple operation. Easy to reach controls minimize operator fatigue.
Ergonomic Operator's StationThe full width operator’s station provides a view of the front loading conveyor and side plates for precise and rapid positioning.
Suspension SeatDurable suspension seat with armrest provides optimum operator comfort.
Warning Horns and Shut Down ButtonsLocated on the operator’s station and at ground level control stations.
Hydrualically Operated Canopy OptionFull 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 ControlsThe 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 DisplyA 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 ControlA 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 Feature
Full flush cutting operation with hydraulic control of the right rear leg, allows the PM102 to be used up close to a curb, wall or guard rail.
Flush CuttingThe 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 DesignThe swing-in arm mechanism ensures increased rigidity eliminating excessive wear for increased component life.
Automatic ControlThe 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.
Steering Right Rear Track
Optimum machine handling for precise control and production.
Precise ControlA 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 AbilityThe 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.
Automatic Grade and Slope Control Option
The optional grade controls provide precise control of rotor to a preset cutting depth. System can be configured to control grade or cross slope.
Contacting Wire Rope Grade SensorsWire 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 BoxesTwo 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.
