Caterpillar Updates to Half-lane Milling Machines


Cold Planers and Milling Machines

Caterpillar Half-lane Milling Machine

Caterpillar PM620, PM622, PM820, PM822, and PM825 half-lane milling machine updates include expanded LED lighting, integrated Cat Grade with Grade and Slope system, and improved serviceability.

The 2021 updates are the third update to these models since they were first introduced in 2016.

New wide-dispersion LED work lights come standard and provide an improved, well-lit work area for ground crew. LED perimeter lights can also be added to further illuminate the rotor chamber, cutting path, and work areas around the machine. New entry/exit lighting provides illumination to the ladder and operator platform when the machine is off. The forward-folding canopy option now features dimmable LED strip lights mounted to the underside of the canopy to improve visibility on the operator platform. When the canopy is lowered, the lights continue to illuminate the controls.

The integrated Cat Grade with Grade and Slope system includes automated features like obstacle jump and programmable cut transitions to aid in milling precision. Cat cold planers can also be enhanced with full 3D milling operation.

Serviceability improvements include longer-lasting conveyor flashing, improved rotor drive access, corded pendant for the rotor turning device, and an added wear shoe for the inboard ski. Cat milling machines are designed with long maintenance intervals, large service doors, and power hood for walk-in access to critical components and systems.

Track pads are easy to replace, the company says, while track chains and other undercarriage components are maintenance-free up to 4,000 hours.
