PM620, PM622, PM820, PM822 and PM825 cold planers are high-production, highly maneuverable half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass.
Caterpillar Inc. has announced updates to the PM620, PM622, PM820, PM822 and PM825 half-lane cold planers.
These milling machines now meet U.S. EPA Tier IV Final and EU Stage V emission standards powered by a fuel-efficient Cat C18 turbocharged, 6-cylinder diesel engine. The PM820, PM822 and PM825 cold planers feature an increased power rating of 800.6 hp (597 kW) gross power. The engine now features multi-piece, cartridge-style filters. This design is environmentally friendly, reducing waste and lowering replacement costs.
Enhanced Operator Comfort and Productivity
Updated handrails increase operator comfort and ease-of-use in flush cutting applications. The new pivoting handrails stow and redeploy easily on the right-hand side when an obstacle comes close to the machine. Obstacle jump is easier to execute from the operator platform with new visual indicators located on the top edge of the side plates indicating where the rotor is positioned and correlate with the markings on the side plate.
More Traction with Reduced Maintenance
Further enhancements include an updated track pin design. A lower pin location increases tractive effort and force on the undercarriage when milling in deep or hard applications. New hardened steel bolt-on wear skis run the full length of side plates and a wear shoe on the anti-slab assembly reduce wear and maintenance.
System K Rotors Optimized for Cat Cold Planers
Cat cold planers are available with the Cat System K milling rotors and feature efficient material flow with an excellent cutting pattern. Rotors are available with spacings of .3, .6 and .7 in. (8, 15 and 18 mm) for a wide range of milling applications. The dual taper retention design provides a reliable method for holding the tool holders in the blocks without the need for a retaining pin or bolt. Reversible paddles and high strength alloys offer more resistance to abrasion and reduce wear for extended rotor life.
Optional Cat diamond bits feature a new design for the System K rotors and last up to 80 times longer than conventional carbide bits to extend intervals between bit maintenance, increase production and reduce operating costs. Cat Diamond Bits are sharper than conventional carbide bits, allowing the machine to cut faster and to reduce drag on the cutting system for better fuel economy in demanding applications, according to the manufacturer.
PM620, PM622, PM820, PM822 and PM825 cold planers are high-production, highly maneuverable half-lane milling machines that perform controlled full-depth removal of asphalt and concrete pavements in a single pass. A variety of options, including the integrated Cat Grade Control system, can be installed to customize the machine to optimize versatility, productivity and comfort.
