DGY70H Tracked Pipe Laying Machine: Core Features and Advantages (70-ton heavy-duty flagship, H = heavy-duty reinforced / high stability / high reliability, suitable for ultra-large pipe diameters of DN2000–DN2400 / extreme long-distance pipeline projects)
1. Superior Lifting Performance: Excellent Efficiency and Safety in Heavy-Duty Operations
With a rated lifting capacity of 70t and ample torque reserve, it can lift ultra-large diameter pipelines from DN2000 to DN2400 and above, covering multi-position operations such as long-distance pipelines, station construction, urban pipe networks, and cross-sea/submarine pipelines. Frequent site relocation is unnecessary, making it particularly suitable for confined spaces such as narrow trenches, high slopes, and wetlands.
2. Reinforced Heavy-Duty Chassis: Stability and Passability Surpass Comparisons
A dedicated heavy-duty chassis with a four-link counterweight and balanced weight distribution provides exceptional anti-tipping performance. When lifting large-diameter pipelines, its stability far surpasses that of wheeled cranes of the same tonnage, making it suitable for long-distance heavy-load travel.
Optimized track parameters and low ground pressure allow it to easily handle harsh road conditions such as mud, sand, desert, mountains, and wetlands. Optimized track center distance enables on-the-spot turning, making it highly adaptable to operations in narrow trenches and mountain trails.
3. Extremely adaptable to various operating conditions, enabling all-weather global operation.
Extreme environmental tolerance allows for stable operation in extreme environments such as -40℃ frigidity, +65℃ high temperature, 4500m altitude, and coastal salt spray, covering major pipeline construction areas worldwide.
Mature and reliable power configuration, excellent fuel economy, highly compatible parts, and a comprehensive maintenance network make it suitable for long-term operation in remote construction sites.
