Overview


The SP/CPX Series are fully hydraulic pipelayers which have been converted from either a Cat mechanical pipelayer or a Cat dozer. The mechanical pipelayer requires only a Hydraulic Kit whereas a dozer requires both a Hydraulic Kit and drawworks. This is known as a full Conversion Package. Both the Hydraulic Kit and Conversion Package are also available for purchase as standalone items for you to install on your own machine.
