sidebooms are machines that are engineered for the unique needs of the pipeline operation. Cat® pipelayers are built for low ground pressure and greater side-to-side stability. The new PL87 and PL83 pipelayers and sidebooms have specifically addressed slope capability with a lengthened track roller frame and re-positioned rear idler puts more track on the ground. The all new counterweight profile adds more weight providing increased lift capacity for that larger inch pipeline work. Both the PL83 and PL87 pipelayers and sidebooms come standard with a Roll Over Protection Structure (ROPS), keeping safety at the forefront. The cab option is available for these models addressing safety as well as operator comfort.
