Cat New Pipelayer

September 28, 2010

Caterpillar®’s new PL61 Pipelayer provides a machine with 40,000 pounds (18 145 kg) of lift-capacity and has a SystemOne™ undercarriage designed to reduce undercarriage costs by 35 to 70 percent.

The PL61 shares many components with the Caterpillar D6K tractor, featuring a Cat® C6.6 ACERT™ engine, closed-loop hydrostatic drive system, oval-track SystemOne™ undercarriage and an electronically enhanced operator station. Features retained from the design of the predecessor model, the 561N, include hydrostatic draw-works, two-speed load line and extendible counterweight.

The extendible counterweight, designed to enhance machine stability when handling heavy loads or when working in steep terrain, can be retracted for maneuvering on confined sites. Counterweight frames are available for both standard-track and low-ground-pressure-track machines, and frame-conversion kits allow changing between the two configurations.
