The Cat PM312 is a highly efficient and maneuverable milling machine with a cutting width of 1225 mm (48.2 in), engineered for controlled full-depth removal of asphalt and concrete pavements in a single pass. Featuring integrated Cat GRADE technology and the latest System K rotors, it ensures outstanding performance, productivity, and cutting precision. The operator enjoys a comfortable environment with intuitive controls at their fingertips, while extended service intervals and easy maintenance access simplify servicing. Though primarily designed for single-operator use, the PM312 includes additional features to support ground personnel. Various options are available to enhance machine versatility, catering to scenarios requiring optimal maneuverability or high production capabilities.
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.
