DGY45 Pipeline Laying Machine Features
1. 45-ton lifting capacity
The DGY45 has a maximum lifting capacity of 45 tons, classifying it as a medium-to-large crawler-type pipe-laying crane.
2. Specifically designed for oil and gas pipeline construction
The DGY45 is not an ordinary crawler crane; it is a specialized piece of equipment designed specifically for pipeline construction.
Main applications include: pipeline hoisting, pipeline assembly, pipeline alignment, pipeline trenching, pipeline laying, and pipeline construction site relocation.
3. Tracked chassis, suitable for field construction.
The DGY45 uses a tracked chassis:
Track center distance: 2,250 mm, Track ground contact length: 3,050 mm, Track plate width: 660 mm, Average ground contact pressure under no-load: 0.082 MPa
4. Hydraulic pilot control for easier operation.
The DGY45 uses Hydraulic Pilot Control.
System rated working pressure: 20 MPa. For pipeline construction requiring frequent lifting, lowering, luffing, and traveling operations, hydraulic pilot control facilitates smoother and more precise control.
5. Lifting Mechanism: Hydraulic Drive + Planetary Transmission
The DGY45's lifting mechanism uses a hydraulic drive + planetary transmission system and is equipped with a Free Fall Function. This structure is particularly suitable for pipeline construction where rapid and flexible hook position adjustments are required.
6. Luffing Mechanism: Also Hydraulic Driven
The luffing mechanism uses a hydraulic drive + planetary transmission system.
7. Intelligent Torque Limiter: Real-time monitoring of lifting torque, automatic overload alarm, and limitation of dangerous actions to prevent tipping accidents, complying with domestic and international pipeline construction safety standards.
8. Mechanical Anti-Tipping Protection Frame and Counterweight Locking Device: Multiple protections in high-risk conditions such as slopes and trenches; the counterweight uses a four-bar linkage mechanism, allowing for quick disassembly during transport, meeting highway width and height restrictions. Equipped with a multiple braking system: normally closed hydraulic brake for the winch, travel brake, and stop lock, ensuring safety and reliability.
