Caterpillar® Pipelayers, are purpose built for your lowering in needs and are designed to be durable and to deliver low operating costs. And they have been proving it in pipeline construction applications throughout the world since 1951. Lowering the welded pipe into the trench demands close coordination and skilled operators. Using a series of pipelayers, operators simultaneously lift the pipe and carefully lower the welded sections into the ditch while moving forward. Rollie-cradles, cable slings with urethane rollers, protect the pipe and coating as it is lifted and moved into position.
