Underground Pipe Laying Machine

The DGY40G is a 40-ton heavy-duty pipeline lifting machine from the DGY series, specifically designed for ultra-large diameter steel pipes/corrosion-resistant pipes (DN1400–DN1800 and above), ultra-long-distance pipelines, and extreme working conditions such as mountainous areas, deserts, wetlands, high altitudes, and coastal salt spray environments. Its core features include strong lifting capacity, stable chassis, precise operation, comprehensive working conditions, easy maintenance, and long service life. It is a core lifting equipment for large-scale oil and gas, municipal, and cross-sea pipeline projects both domestically and internationally, and is a top choice for both export and national key projects.

1. Superior Lifting Performance: Excellent Efficiency and Safety in Heavy-Duty Operations

● With a rated lifting capacity of 40t and ample torque reserve, it can lift ultra-large diameter pipelines (DN1400–DN1800 and above), covering multi-position operations in long-distance pipelines, station construction, urban pipe networks, and cross-sea pipelines. It eliminates the need for frequent site changes and is particularly suitable for confined spaces such as narrow trenches, high slopes, and wetlands.

● Precise electro-hydraulic control and excellent micro-motion performance ensure high pipe alignment accuracy, good weld quality, and reduced rework; the hydraulic system boasts high reliability, with a continuous operation attendance rate of ≥95%, significantly improving construction efficiency.

● Multiple safety protection devices and a low center of gravity design prevent rollovers, overloading, and other safety accidents, making it suitable for high-risk working conditions.

2. Reinforced heavy-duty chassis for superior stability and maneuverability compared to its competitors.

● Dedicated heavy-duty chassis and balanced weight distribution provide exceptional anti-tipping performance, offering stability far exceeding that of wheeled cranes of the same tonnage when lifting large-diameter pipes, making it suitable for long-distance heavy-load travel.

● Optimized track parameters and low ground pressure allow for easy handling of 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 narrow trenches and mountain trails.

● High-strength track links and high-quality travel motors/reducers are wear-resistant, impact-resistant, have a low failure rate, and low maintenance costs, making them suitable for long-term heavy-load travel.

3. Extremely adaptable to various operating conditions, enabling all-weather global operation.

● It boasts exceptional environmental tolerance, capable of stable operation in extreme environments such as -40℃ frigidity, +60℃ heat, 3000m altitude, and coastal salt spray, covering major pipeline construction areas worldwide.

● Its mature and reliable power configuration offers excellent fuel economy, strong parts compatibility, and a comprehensive maintenance network, making it suitable for long-term operation in remote construction sites.
