Caterpillar updates its cold planer lineup

Caterpillar has introduced the third update to its half-lane cold planer lineup since the machines were introduced five years ago. 

The Cat PM620, PM622, PM820, PM822 and PM825 half-lane cold planers include numerous improvements based on customer feedback, designed to  ease operation and lower owning and operating costs. 

Caterpillar introduced a new lineup of cold planers about five years ago. Since the machines’ introduction, the company has continuously been working on improvements to the planers. The latest product release marks the third update to these models since they were first introduced.

The 630 hp PM620 and PM622 are powered by the Cat C18 engine. The heavier and more powerful PM820, PM822 and PM825 are powered by the same engine with a twin-turbo setup to deliver 800.6 hp, which translates to as much as 27 per cent more power than the PM620 and PM622. All five models meet Tier 4 Final, Stage V and emissions standards and are optimized to reduce fuel burn with a high-capacity cooling system that keeps the engine at ideal temperatures for optimal fuel efficiency and lower emissions.

Integrated tech 

The integrated Cat GRADE with Grade and Slope system takes the guesswork out of producing accurate and repeatable cutting results and includes automated features like obstacle jump and programmable cut transitions to aid in milling precision. 

As well, Cat cold planers can be equipped with full 3D milling operation.

The cutting system is designed to withstand tough applications and built with heavy steel construction and reinforced alloys to resist abrasion. Available in a wide variety of spacings, Cat System K rotors are durable and deliver  efficient material flow and an excellent cutting pattern. 

The Kicker paddles are reversible for extended life, and the tapered dual retention toolholder design eliminates the need for retaining bolts, pins, or setscrews, reducing replacement time by up to 50 per cent.

A track undercarriage system with well-engineered track geometry provides high tractive effort and better load distribution when milling deep cuts or through hard materials. The cold planers’ high capacity conveyors provide efficient removal of milled material with discharge control. The belt also reverses for faster clean-up, while magnetic vinyl covers provide quick access to inspect the rollers for wear. Optional dust ventilation and spray bar systems maximize dust removal.

New lighting options

The cold planers are equipped with new LED lighting to enhance nighttime and low-light operation. The wide-dispersion LED work lights are standard and provide an improved work area for ground crew. 

Furthermore, LED perimeter lights can be added to further illuminate the rotor chamber, cutting path and work areas around the machine. Cat has also added new entry/exit lighting, which provides illumination to the ladder and operator platform when the machine is off. 

The forward-folding canopy option features dimmable LED strip lights mounted to the underside of the canopy to further improve visibility on the operator platform. When the canopy is lowered, the lights continue to illuminate the operator-friendly controls.

Improved serviceability

Longer lasting conveyor flashing, improved rotor drive access, corded pendant for the rotor turning device and an added wear shoe for the inboard ski are just a handful of the many improvements included in the cold planer product update. 

The milling machines are designed with long maintenance intervals, large service doors and power hood for walk-in access to critical components and systems. 

The track pads are easy to replace, while track chains and other undercarriage components are maintenance-free for up to 4,000 hours
