Description:

1. the traction and propulsion mechanism utilizes the rexroth (germany) automatic control system operating under load-sensing control: compared to traditional systems, it achieves 15%–20% higher thrust force, 15%–20% improved efficiency, ~50% energy savings, and reduced heat generation.

2. equipped with a cummins engine specifically designed for engineering machinery requiring high efficiency, powerful output, low fuel consumption, low noise, and robust operational capabilities.

3. features a high-power cummins engine for enhanced performance.

4. includes an auxiliary booster device to increase traction force, with a maximum pulling force of 900 kn, ensuring structural safety during large-diameter construction.

5. the mud pump adopts a four-layer sliding plunger structure, significantly improving suction angles and preventing separation between large particles, boreholes, and the ground.

6. equipped with a reversible electromagnetic vibrator for loading/unloading drill rods, dramatically reducing labor intensity and improving work efficiency.

7. fitted with φ89×3000mm, φ114×3000mm, and φ127×3000mm friction drums for medium-duty applications, meeting requirements for high-efficiency construction structures.

8. key hydraulic components sourced from world-leading hydraulic manufacturers, ensuring exceptional operational reliability and safety.

9. optimized electrical design with low failure rates and easy maintenance.

10. employs a rack-and-pinion traction/propulsion system for high efficiency, long service life, stable operation, and simplified maintenance.

11. steel crawler tracks with patterned surfaces enable loading capacity and stable movement across diverse terrains.

12. the GS450AT-LS rock drilling rig utilizes “casing-within-casing” technology, delivering effective operation in hard rock conditions and high efficiency in general environments.
