Pipelayer

Pipelayer adopts Cummins Engine, exclusive track-type chassis, rigid structure, widening and lengthening track and hydraulic mechanical transmission. Its working equipment adopts full hydraulic drive, which mainly achieves three main movements: the lifting and landing of the hook, boom's swing, lifting and landing of the balance weight. Pipelayer has good micro-drive performance and rapid drop-hook function. As the important construction equipment of the oil and gas pipeline construction, pipelayer is mainly used in the layout, lining up and lowering of large-diameter pipe.
