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.

FAQ
Q: What is the difference between a pipe-laying machine and a pipe-laying device modified from a regular excavator?
A: The DGY series uses a factory-dedicated pipe-laying machine chassis with a specially optimized center of gravity for enhanced lateral stability; equipped with a dedicated side-lifting winch, anti-tilt protection, and pipe hook; excavator modifications lack sufficient lateral lifting stability, and long-term heavy-load use is not recommended for pipeline projects.
Q: Can the equipment be used in mountainous or muddy swamp conditions?
A: Standard widened track shoes provide low ground pressure and good mobility in muddy areas; however, for steep slope operations, strict adherence to operating procedures is required, and lifting loads must be controlled; heavy-load operations on cross slopes are prohibited.
