PM312 Track Undercarriage Cold Planer

Mill with precision

The Cat PM312 is an efficient, highly maneuverable milling machine with a cutting width of 1225 mm (48.2 in) that performs controlled full-depth removal of asphalt and concrete pavements in a single pass. Integrated Cat GRADE and the latest System K rotors deliver performance, productivity and cutting precision. A comfortable operator environment puts intuitive controls at your fingertips, while long service intervals and easy maintenance access simplifies service. While designed for a single operator, the PM312 includes added features for supporting ground personnel. Many options are available to enhance machine versatility when optimum maneuverability or high production capabilities are required.

    Benefits

    Comfortable Operation

    An ergonomically adjustable work area puts intuitive controls at your fingertips for operation while seated or standing. A 14-button ground-level keypad and optional display gives supporting personnel access to numerous machine controls.

    Milling Precision

    Integrated technology and Cat System K rotors help achieve excellent cutting patterns and profiles. Cat track undercarriages offer smooth operation and a balance between traction, speed and maneuverability.

    Low Cost of Ownership

    Maintenance-free track components and extended service intervals not only reduce downtime but decrease the amount of labor needed and parts replaced over the life of the machine.
