PM312 Track Undercarriage Cold Planer

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.
