DGY20 hydraulic crawler pipelayer Machine Core Advantages (20-ton class, suitable for oil and gas/municipal pipeline projects & international trade)
The DGY20 hydraulic crawler pipelayer is an upgraded heavy-duty model of the 15-ton class (DGY15), specifically designed for large-diameter, long-distance, and complex pipeline laying (jointing, trenching, hoisting and transportation). Its core advantages focus on four dimensions: upgraded lifting performance, stronger chassis load-bearing capacity, wider adaptability to working conditions, and superior total life-cycle cost. It is a mainstay model for medium and large-scale pipeline construction.
- Superior Lifting Performance, Doubling Heavy-Duty Operation Efficiency
- Significantly Increased Rated Lifting Capacity and Torque
- Precise and Efficient Hydraulic System, Maximizing Micro-Motion Capability
- Wideer Operating Coverage, Especially Suitable for Mountainous Areas and Narrow Trench Areas
- Upgraded Heavy-Duty Chassis, Unrivaled Stability and Passability in its Class
- Extremely Adaptable to Working Conditions, All-Weather Global Operation
- Mature and Reliable Power Configuration, Excellent Fuel Economy
- Durable Structure, Convenient Maintenance, Meeting Diverse Transportation and Construction Needs The DGY20 pipe-laying jack, with its 20-ton heavy-duty lifting capacity, upgraded chassis stability, all-condition adaptability, high cost-effectiveness, and established market reputation, is the preferred model for large-diameter pipeline laying and complex lifting operations. It represents a comprehensive upgrade in lifting capacity, load-bearing capacity, and operating range, perfectly adapting to the construction needs of medium and large-scale pipeline projects in domestic and international oil and gas, municipal, and long-distance pipeline projects.

FAQ
Q: How many operators are needed for one pipe-laying machine?
A: One operator is standard. Ground pipeline support personnel will be assigned separately according to the construction plan.
Q: What type of hydraulic oil is used in the hydraulic system? Are there any recommendations for high-temperature/tropical regions?
A: Use 46# anti-wear hydraulic oil at room temperature; 68# anti-wear hydraulic oil is recommended for tropical high-temperature environments.
