There are many advantages of buying and using purpose-built pipelayers over converted crawler tractors for pipe-laying applications. These advantages make a huge difference in capacity and performance of the machines and profitability for your company. Cat Pipelayers are built from the ground up with your job tasks in mind and are designed for the needs of pipeliners. Cat Pipelayers are built for low ground pressure and greater side-to-side stability. The track shoes are wider than a standard crawler tractor, thereby improving flotation, protecting the ROW and minimizing side tipping. A purpose-built pipelayer has an undercarriage longer and wider than that of similarly sized dozers. A standard dozer is designed with a narrower gauge (the gauge of a tractor is the measure of center of the roller frame to the center of the other roller frame) best suited for the applications of a bulldozer where pipelayers have a wider gauge, which equates to greater side-to-side stability.
