Caterpillar has announced a series of upgrades to its PM310, PM312, and PM313 Cold Planers, marking a leap forward in machine performance, operator comfort, and environmental efficiency, says the firm.
The enhancements are designed to cater to the demanding needs of small to medium-scale milling operations, where compact size, maneuverability, and high production capabilities are paramount.
Central to the improvements is the integration of the advanced Cat C9.3B engine across the PM300 series. This powerhouse not only boosts gross power to 256 kW (343 hp) but also provides an uptick in torque availability. Engine configurations are tailored to meet diverse global emission standards, including the U.S. EPA Tier 4 Final, EU Stage V, Korea Stage V, and Brazil MAR-1, making these machines adaptable and compliant across international markets.
The Cat C9.3B engine distinguishes itself with simplified maintenance features, such as easily accessible engine oil filters and environmentally friendly, cartridge-style engine filters designed to minimize waste and cut down on replacement costs. These improvements stem from a concerted effort to reduce complexity and enhance the efficiency of the electronic, fuel, and air systems.
Beyond the engine enhancements, the latest PM300 series boasts several design upgrades aimed at augmenting performance and comfort. A notable redesign is the transition flashing between the primary and loading conveyors, which has been optimized to improve material containment and mitigate build-up on the machine’s front frame. Additional modifications to the right-hand side plate, chamber-to-conveyor sealing, and loading conveyor belt sealing further enhance material containment, contributing to cleaner, more efficient operations.
In a bid to improve operator and ground personnel safety and comfort, the series now includes wide-dispersion LED working lights and LED roading lights, enhancing visibility during both milling operations and transportation. An adjustable on-screen guidance line feature added to the left-hand camera facilitates precision cutting, while the rear ground controls have been updated to allow ground personnel to manage the obstacle jump capability, streamlining the milling process.
The introduction of an exhaust deflector option, which can be stowed when not in use, alongside redesigned dust abatement ducting, underscores Caterpillar’s commitment to creating a healthier work environment. These additions are aimed at directing exhaust and dust away from operators and ground personnel, significantly improving the overall working conditions on job sites.
