HGY pipelayer is mainly used for pipe hoisting operations in pipeline construction, such as pipe transportation, pipe laying, assembly and trenching. The pipelayer chassis is a special hydraulic chassis for developed on the basis of mature excavator chassis technology. The traveling system adopts hydrostatic transmission mode, with small impact on start and stop, and can realize in-situ steering; The lifting system adopts full hydraulic transmission, with stable transmission and good micro motion performance. Compared with the traditional bulldozer chassis pipelayer, it has obvious technical and application advantages.
HGY pipelayer has reasonable design, compact structure, easy dispatch, transfer and transportation, and can meet the requirements of railway transportation and self-crawling flat trailer transportation. Adapt to the construction site and general road operation.
