Efficient Performance
Powerful Cat® C18 twin-turbo engine meets regional emission standards
Smooth and efficient operation with Automatic Idle Control and multiple rotor speeds optimize output and demand on the engine
High capacity cooling system keeps engine at ideal temperatures for optimal fuel efficiency and lower emissions
Automatic load sensing on the rotor adjusts milling speed to prevent stalls and optimize production
Maneuverability and Control
Reliable track undercarriage leverages proven designs from Cat dozers and an automatic tensioning system to ensure consistent performance and longer track life
Robust propel system features two independent propel pumps to drive two crawler tracks each, in a high-traction, cross-drive pattern
Automatic traction control maintains consistent speed in the most challenging applications
Four steering modes with advanced alignment and tracking provides precise steering geometry and reduces track pad wear
Ability to electronically switch between rotor speeds during operation
Comfortable Work Environment
Operate in comfort with height-adjustable operating consoles and intuitive, ergonomic controls
Retractable handrails stow and redeploy easily when approaching obstacles
Work day or night with backlit keypads and illuminate the work area around the machine with wide-dispersion and perimeter LED lighting options
Upgrade operator stations with optional suspension seats that reposition for improved visibility and comfort
Optional remote cameras enhance visibility to the cutting edge and conveyor
The single post, forward-folding powered canopy option with overhead LED lighting and integrated side extensions quickly stows and redeploys during operation to clear overhead obstacles with the simple push of a button, and optional windscreens can be added for increased comfort
Maximize dust removal from the working areas with the optional dust abatement system
Material Removal
High-capacity conveyors provide efficient removal of milled material with outstanding discharge control
A wide opening and seamless belt effectively clear the rotor chamber
Adjust the belt speed to match material type and production rate, while the built in “boost” feature provides a temporary surge in belt speed to eject material faster and farther
The belt reverses for faster clean-up, while magnetic vinyl covers provide quick access to inspect the rollers for wear
Boost Precision with Integrated Technology
Achieve accurate, repeatable and automatic cutting precision with the integrated Cat GRADE with Grade and Slope system
Control boxes can be repositioned without the need to reconfigure settings and the background color changes to night mode when the work lights are activated
Obtain full control of grade and slope from any control box
Seamlessly switch between multiple grade sensors for uninterrupted accuracy during milling
Adjust the speed at which the rotor drops into the cut for optimal machine control
Set and automate transitions in/out of cuts and save settings for future jobs
Clear obstacles in the cutting path with ease using the obstacle jump feature
Enhance for full 3D milling operation (additional hardware required)
Simplified Service
Maintenance is easier and faster with large service doors and power hood for walk-in access to critical components
Maintenance-free track components and easy to replace track pads lower service costs
Standard ground-level controls and an optional electrically-operated rotor turning device with pendant simplify bit removal and replacement
High and low pressure washdown options connect to the onboard water tank for convenient clean-up
Operate select machine functions during maintenance and service with the accessory drive system
Electrical system wiring is color-coded and numbered for easy identification and wrapped in a protective, abrasion-resistant nylon braid for longer life
Extended hydraulic oil service intervals: 3000 hours without oil sampling, 6000 hours with oil sampling
Track scheduled maintenance with Cat Product Link™ telematics services
Electronic Control Modules (ECMs) monitor machine systems to alert the operator of performance issues and can be paired with Product Link options to enable additional remote services with your local Cat dealer
Multi-piece, cartridge-style engine filters are environmentally friendly, reducing waste and lowering replacement costs
Convenient parts availability, dealer locations and service repair kits simplify ordering of high wear components
System K Rotors
Cat System K rotors feature efficient material flow with an excellent cutting pattern for numerous applications
A tapered dual-retention design secures toolholders in place without a retaining pin, bolt or setscrew, speeding up replacement and eliminating the need for fasteners or torqueing
Reversible paddles and high strength alloys reduce wear and abrasion to extend rotor life
Optional diamond bits can extend replacement intervals up to 80 times longer than conventional carbide bits
Durable Cutting System
The rotor drive system features a heavy-duty dry clutch, automatic belt-tensioning to prevent slippage and two high tensile (five-rib) belts to drive the rotor
Reinforced cutting chamber offers enhanced durability
Improved access simplifies rotor changes
Hardened full length side plate skis, inboard ski shoe, and anti-slab shoes reduce wear and maintenance
Convenience Features
Cat cold planers offer a variety of features and options designed to make daily operation and maintenance tasks easier.
Pause and resume machine functions with the push of a button during truck exchanges
Optional magnetic paint can holders
Hooks for water hose storage
Angled water fill connection
Easily accessible shovel holder
Top and side view rotor depth indicators
Compressed air connection in center operator console
Sustainability
The Cat C18 engine meets U.S. EPA Tier 4 Final, EU Stage V, Korea Tier 4 Final and China Nonroad Stage IV emission standards.
Cat U.S. EPA Tier 4 Final, EU Stage V, Korea Tier 4 Final and China Nonroad Stage IV diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrogenated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
Automatic Idle Control helps reduce unnecessary fuel burn and greenhouse gas emissions by allowing the engine to automatically go into idle mode when the machine is not working.
Automatic Load Control helps you save fuel and reduces greenhouse gas emissions by automatically matching milling speed to engine load for maximum production at peak efficiency.
Standby/Resume pauses major machine functions and lowers engine speed to conserve fuel and helps reduce greenhouse gas emissions during truck exchanges.
Traction Control maintains consistent traction to increase machine efficiency, helps reduce fuel burn and greenhouse gas emissions.
The engine, Diesel Exhaust Fluid (DEF) if equipped, fuel and hydraulic systems are equipped with ecology drains for easy servicing and to help prevent spillage.
Extended maintenance intervals not only reduce downtime but decrease the amount of fluid and filters that are replaced over the life of the machine: hydraulic oil 6000 hours with sampling, coolant 12000 hours with extender.
Cat Scheduled Oil Sampling (S•O•S℠) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine’s operation and maintenance manual for more information.
Cat Grade with Grade and Slope for cold planers allows for accurate material planning to help reduce overages during the paving process and increase final project quality for a longer lasting road surface.
Don’t waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
*Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel.
