The HGY-R series rotated pipelayer is mainly applied in the construction of oil and natural gas pipeline, which belongs to the special equipment for transportation, pipe distribution, group matching and trench construction conditions. The chassis is a special hydraulic chassis developed on the basis of mature excavator technology. The driving system adopts hydrostatic transmission mode, which has small impact on starting and stopping, it can realize in-situ steering. Compared with the traditional, the equipment transfer does not need to remove the big arm and counterweight, improving the transfer efficiency.
