| Caterpillar's 2.2m Rotor Option for the PM200 Cold Planer  Caterpillar Inc. announced the availability of the PM200 Cold Planer with an optional 2.2m cutting rotor. Customers now have two cutting width options when purchasing the PM200: the standard 2.0m rotor or the new 2.2m rotor option. The new 2.2m rotor option provides greater efficiency and productivity by reducing passes during applications that benefit from a wider cutting rotor, such as mainline, high productivity milling. Fewer passes will contribute to a reduction in fuel burn. The standard 2.0m rotor provides greater versatility for urban applications and milling tasks that require a high degree of maneuverability and precision.The PM200 is a high-production, highly maneuverable half-lane milling machine that performs controlled full-depth removal of asphalt and concrete pavements in a single pass. Operating weight for the PM200 is approximately 30 100 kg with the standard 2.0m rotor package; the weight increases to 31 500 kg with the optional 2.2m rotor package. Both the 2.0m and the optional 2.2m wide rotors feature conical tool holders and have a maximum cutting depth of 320 mm. The 2.0m conical tool holder rotor is equipped with 178 carbide-tipped tools, and the optional 2.2m conical tool holder rotor is equipped with 193 carbide-tipped tools. Both rotor options position the tools in durable three-piece, quick release tool holders arranged in a chevron pattern for maximum breakout force. The quick release conical tool holders feature a tapered fit, maintaining tightness in the holder base. The mandrel features large, replaceable, carbide-faced loading paddles to effectively move milled material onto the collecting conveyor, resulting in higher production and less wear on the inside of the rotor chamber and cutting tools. Triple-tree tool placement on rotor end cutters provides optimum tool spacing to clean up loose material and reduces wear on the rotor when maneuvering in the cut. There is an optional dust-reduction package available for PM200 machines equipped with the 2.2m rotor option. The attachment will more efficiently control dust during operation. It includes an additional water pump as well as additional spray bars located inside the rotor housing and conveyors. write your comments about the article :: © 2010 Construction News :: home page |
