Pipelayeradopts Cummins Engine, exclusive track-type chassis, rigid structure, widening andlengthening track and hydraulic mechanical transmission. Its working equipmentadopts full hydraulic drive, which mainly achieves three main movements: thelifting and landing of the hook, boom's swing, lifting and landing of the balanceweight. Pipelayer has good micro-drive performanceand rapid drop-hook function. As the important construction equipment of theoil and gas pipeline construction, pipelayer ismainly used in the layout, lining up and lowering of large-diameter pipe.
