PM201 Caterpillar PM201 Specifications & Technical Data (2017—2019)

C18 Cylinder Block

The cylinder block is a one-piece, grey iron block that features generous ribbing for stiffness and heavy bearing bulkheads for rigidity and strength as the crankshaft turns. This new design supports the engine’s higher compression ratios and increases its power density. The incorporation of straight-thread, o-ring connection points reduces the loss of engine oil and fluids.

C18 Engine with ACERT Technology

ACERT Technology works at the point of combustion to optimize engine performance and provide low exhaust emissions. The C18 engine with ACERT Technology provides clean burning power.

Optimum Power

The C18 engine performs at a full-rated gross power of 485 kW (650 hp) at 2100 rpm. The combination of large displacement and high torque allow the PM201 to achieve maximum production. Engine power curve is optimized for milling applications providing optimum power while keeping the engine operating at peak efficiency.

Mechanically-Actuated Electronically Controlled Unit Injection (MEUI)

The MEUI fuel system is a unique system that combines the technical advancement of an electronic control system with the simplicity of direct mechanically controlled unit fuel injection. The MEUI system excels in its ability to control injection pressure over the entire engine operating speed range. These features allow the C18 to have complete control over injection timing, duration and pressure.

Precise Multiple Injection Fuel Delivery

Combustion chamber temperatures are lowered by precisely shaping the combustion cycle generating fewer emissions and optimizing fuel combustion; translating into more work output for your fuel cost.

High Cylinder Pressures

High cylinder pressures combined with tightly controlled tolerances promote extremely efficient fuel burn, less blow by and lower emissions.

Turbocharged and Air-to-Air Aftercooling (ATAAC)

High horsepower with increased response time is assured while keeping exhaust temperatures low for long hours of continuous operation.

Air-to-Air Aftercooling

Air-to-air aftercooling keeps air intake temperatures down and in concert with the tight tolerance combustion chamber components, maximizes fuel efficiency and minimizes emissions. New turbocharger, unique cross-flow head design, single front driven overhead cam and a more efficient intake manifold generate significant improvements in air flow, maximizing efficiency and reduced emissions.

ADEM™ A4 Electronic Control Module

The module manages fuel delivery, valve timing and airflow to get the most performance per liter (gallon) of fuel used. The control module provides flexible fuel mapping, allowing the engine to respond quickly to varying application needs. It keeps track of engine and machine conditions while keeping the engine operating at peak efficiency.

Rotor Drive

A Caterpillar wet clutch with automatic belt tension adjustment delivers efficient and reliable power to the pavement. The rotor drive consists of field-proven Cat D8 Track-type Tractor components for Caterpillar machine commonality and long service life. Additionally, the Caterpillar wet clutch is the most efficient and reliable system of applying rotor power to the pavement. The rotor clutch system has a separate oil sump, pump, filter, clutch control valve, and oil cooler to provide continuous cooling and lubrication.

Upper and lower sheave bearings

Are continuously lubricated with oil from the rotor drive clutch sump to provide long life and reduced maintenance.

Caterpillar drum drive gear reducer

Provides reliability and long service life. An input shear shaft is provided to protect the rotor and final drive from overload conditions. The rotor mandrel is liquid-filled to dissipate heat and cool the gear reducer.

Ecology drains

Provide an environmental method to drain fluids. They are included on the radiator, engine oil pan, and hydraulic tank.

Maintenance-free Caterpillar batteries

Are mounted on the top of the machine and are accessible through a bolt-on cover. Cat batteries are specifically designed for maximum cranking power and protection against vibration.

Cooling package

is a multi-row modular design stacked in series for easy access for cleaning and service. A modular stacked cooling system provides more efficient cooling of individual systems and makes replacement and routine cleaning easier.

Hydraulic System

Pumps for propel, rotor drive, collecting and upper conveyors, auxiliary hydraulics, and cooling fan are installed on the engine mounting pad. The hydraulic oil cooler is located at the rear of the machine and arranged in a modular stacked design for efficient cooling and easy access for cleaning. Three-micron filtration on the pressure side of auxiliary flow and seven-micron filtration on the return side ensure optimal performance. Quick-connect hydraulic test ports simplify system diagnostics.

Front Loading Conveyor

The PM201 features a front loading conveyor for greater productivity. The conveyor swings 45 degrees to the left or right to meet your job requirements. Conveyor functions can be controlled from the operator’s station or at ground level. Conveyor features a boost function to cast material farther for loading long haul trucks. High capacity and versatility adds to productivity. The momentary boost function increases material handling to load long tractor trailers from the rear. The 915 mm (36") wide upper conveyor has hydraulically controlled height adjustment and two cylinders for a 45 degree swing to the left and right. The seamless belt features 25 mm (1") high cleats, offers long service life, and provides better control of fine particles. Variable belt speed controls upper belt loading to match milled material type and amount. Conveyor raise, lower, and swing are controlled from the operator’s station and at two ground level control stations.

Automatic Grade and Slope Controls

The optional grade and slope system provides precise control of the machine to a preset cutting depth and cross slope. Remote mounted control boxes allow simple operation from either the operator’s station or ground level.

Serviceability

The power-assisted engine hood opens wide and provides exceptional walk-in access to the engine, hydraulic pumps, and daily service points. The hydraulic rotor service door provides convenient access to the rotor for easy cutting tool removal and replacement. Water spray nozzles are easily removed for inspection and replacement without the need for tools.

Primary Collecting Conveyor

A large discharge opening and wide collecting conveyor belt clears out the cutter box fast for increased production. The water spray system provides lubrication and controls dust. The large discharge opening clears out the cutter box quickly for increased production. The 1020 mm (40") wide collecting conveyor is driven by two high torque hydraulic motors, providing maximum efficiency. The seamless belt features 25 mm (1") high cleats to clear out the cutter box effectively and provides better control of fine particles. The standard water spray lubricates and controls dust on the collecting belt. Water spray nozzles are easily removed for inspection and replacement without the need for tools. The optional hydraulically operated front door provides adjustable down pressure to prevent slabbing of the road surface, resulting in optimum sizing and gradation. An anti-kickback device automatically deactivates the rotor drive and propel systems if a kickback is detected.

Visual Indicators

Allow easy check of radiator coolant, water spray tank level, hydraulic oil tank level, and air restriction indicator.

Water Spray System

The hydraulically-driven centrifugal pump supplies water to spray nozzles for dust control and collecting belt lubrication. The centrifugal pump is rated at 206 L/min (55 gpm) at 276 kPa (40 psi). Water spray nozzles focus the water spray in a flat fan pattern to the rotor for better cooling of cutting tools. Nozzles are easily removed for inspection and replacement without the need for tools. The automatic water spray system operates only when the rotor is engaged and the machine is moving forward to conserve water. The system includes gauges to monitor water pressure, replaceable filters, a low water level indicator, and water control valves to conserve water usage. The water tank can be filled from the top of the machine or at ground level.

Propel System
