The DGY90 is the flagship 90-ton heavy-duty model in the DGY series, specifically designed for extreme working conditions such as ultra-large diameter steel pipes/corrosion-resistant pipes (DN2200–DN2800 and above), world-class long-distance pipelines,and pipelines operating in mountainous/desert/wetland/high-altitude/coastal salt spray/submarine environments. Its core features include superior lifting capacity, ultra-stable chassis, extremely precise operation, comprehensive working condition coverage, convenient maintenance, and exceptionally long service life. It is a core lifting equipment for extra-large oil and gas/municipal/cross-sea/submarine pipeline projects.
The DGY90 pipe-laying machine is based on 90-ton heavy-duty lifting capacity, high stability with four-link counterweight, precise electro-hydraulic control, all-condition and all-domain adaptability, high cost-effectiveness, and a mature market reputation. Compared to the DGY70H, it represents a comprehensive upgrade in lifting capacity, load-bearing capacity, operating range, power reserve, control precision, environmental adaptability, and chassis life, perfectly adapting to domestic and international oil and gas, municipal, long-distance, and cross-sea/submarine pipeline projects. The heavy-load construction requirements of ultra-large pipeline projects such as those on the seabed.
