PM312

The Caterpillar PM312 attachment represents a proven cold milling solution engineered for contractors managing pavement removal and surface preparation across road rehabilitation and foundation work. This powerful attachment integrates seamlessly with compatible carrier systems, delivering precise milling capabilities that maintain tight tolerances on complex job sites. Its reputation stems from balanced performance: the robust hydraulic architecture handles demanding asphalt and concrete removal while the precision control systems ensure clean, dimensionally accurate cuts essential for overlay preparation and foundation work accuracy. Caterpillar PM312 specifications reflect design priorities centered on operational productivity and operator control. The attachment achieves a 1,200 mm milling width with cutting depths to 330 mm, supported by variable-speed drum technology that adapts to material hardness and aggregate composition. The high-torque hydraulic circuit delivers consistent cutting force across varying surface conditions, reducing cycle time while maintaining edge quality—critical factors for contractors balancing productivity against precision requirements in competitive bidding environments. The Caterpillar PM312 attachment serves multifaceted applications in infrastructure rehabilitation, including mill-and-fill pavement restoration, concrete pulverization for recycling, and site preparation for deep foundation systems. Equipment operators value its modular integration with standard carriers, reducing capital expenditure while expanding fleet capabilities. Whether addressing highway maintenance contracts or specialized foundation work, the PM312 delivers the specification performance and operational reliability that justify its position in modern construction equipment inventories.
