Crawler Track Drill Rig Specifications

MDL-150H Series High-Lift Multifunctional Drill Rig

The MDL-150H series high-lift multifunctional drill rig is designed for versatility and efficiency in various drilling applications. With its capability to lift higher, reach further, rotate faster, and deliver greater torque, this drill rig stands out in the field of geotechnical construction.

Main Features:

1. The torque and rotation speed can be reasonably matched according to actual needs, allowing for 3-meter combined drilling with drill rods and casings. By configuring the appropriate torque and rotation speed for different geological strata, the adaptability of the drill rig is significantly enhanced.

2. Equipped with a track chassis, high-position rotating platform, large-diameter leg cylinders, 1.5-meter sliding frame, and hole mouth support device, the drill rig is highly convenient for moving and positioning, ensuring stable and reliable operation during drilling.

3. The inclusion of a gripping unloader reduces the labor intensity and increases the efficiency of loading and unloading drill rods and casings.

4. Dual oil cylinder excavator-style arm provides excellent stability in any lifting state, with a maximum horizontal lifting height of 3 meters.

5. Capable of operating in horizontal, vertical, upward, and downward angles, meeting the needs of various construction techniques.

6. The track clearance is larger, adapting to harsh construction environments.

7. Suitable for the following construction processes:

   • Anchoring with various drilling methods such as rod drilling, casing drilling, and combined rod and casing drilling.
   • Jet grouting suitable for single, double, and triple jet grouting methods.
   • Pit dewatering.
   • Tunnel support construction.
   • Micro-piling.
   • Geothermal hole (water well) construction and investigation.

8. With the appropriate drilling tools, it can meet the following construction techniques:

   • Three-wing bit drilling with mud flushing, suitable for high-speed drilling in soil and sand strata.
   • Air hammer drilling with air flushing, suitable for rock and broken strata.
   • Bottom hole liquid dynamic hammer drilling with mud flushing, suitable for broken strata and sand and gravel layers with high water content.
   • Casing drill.
   • Single, double, triple jet grouting, and swing spraying, etc.

Application Scope:

The MDL-150H series is suitable for a variety of engineering projects such as subways, tunnels, high slope protection, high-rise buildings, airports, geothermal heat pumps, and other deep foundation pits for pipe shed, anchoring, jet grouting, and dewatering operations.
