Pipelayer adopts Cummins Engine and pilot control. It is equipped with intelligent monitor, automatic hook spacing device and boom spacing device, which can conduct the real-time monitoring and control to the pipelayer's conditions. Pipelayer is mainly applied in the layout, lining up and lowering of large-diameter pipe.
