Caterpillar Introduces Three Purpose-Built Pipelayers

摘要

The Cat PL72, PL83, and PL87 pipelayers feature an integrated, all-Cat power train with differential steering and an electronically controlled hydraulic system that places total control of lifting functions into one single joystick. Independent, variable-speed winches for the boom and hook provide precise control, and the enhanced counterweight system ensures a low center of gravity. A new ROPS provides added safety for both open and enclosed operator's stations. Also, the purpose-built pipelayer cab is now pressurized and incorporates new operator-comfort and convenience features.
