Model Trio Covers Market Range

摘要

With three model sizes, Caterpillar offers fully hydrostatic cold planers to match the breadth of compact, urban and mainline milling applications. The compact PM102 model, available with a tracked or wheeled undercarriage, has a rotor width of 40 inches. The high-productivity PM200 and PM201 tracked cold planers have rotor widths of 79 and 83 inches, respectively. To increase tractive effort in slippery conditions, a positive traction control valve provides equal traction to all four motors on each model. With standard automatic rotor load control, an on-board microprocessor constantly evaluates engine and propel speed as required for peak performance. Propel speed is matched to the engine load so that the engine speed does not dip below a specified level.
