Performance Characteristics
- The 3515AT rig is a full-terrain pipe-laying drilling rig, suitable for pipeline installation across a wide range of complex ground conditions.
- Rotary thrust/pull adopts PLC-constant-power electro-hydraulic control with a load-sensitive system, improving overall efficiency by 20% compared with conventional open-loop systems. It also enhances engine fuel efficiency, lowers operating costs, and delivers energy-saving and environmentally friendly performance. The hydraulic pump is a piston pump with higher pressure rating, longer service life, and greater system efficiency.
- Two-speed range with proportional control for rotation, thrust/pull, and crawler travel, providing infinitely variable speed adjustment.
- Rotation and thrust/pull are controlled by a multifunctional joystick that integrates all main operating movements into one ergonomic control point — simple, convenient, comfortable, and efficient.
- The rotation and thrust/pull functions are driven by imported Rexroth piston motors, delivering high torque and strong impact resistance.
- Gear and rack transmission with double hydraulic motor reducers drives the rotary head trolley forward and backward.
- Crawler travel is controlled from the main control station for safe and reliable operation.
- The boom lifting mechanism keeps the tracks firmly on the ground even at the maximum drilling angle, effectively ensuring rig stability during both drilling and pull-back operations.
- The clamp is angled inward toward the operator, making clamp work easy to observe and monitor.
- A clamp spring buffer device prevents accidental drill-rod thread or clamp damage caused by operator error.
- Welded steel chassis fitted with rubber shoes adapts to various road surfaces, offering high structural strength and long service life.
- Equipped with a mechanical arm, enclosed cabin, and standard air conditioning, it provides a comfortable working environment for drilling crew members and improves overall work efficiency.
