Crawler Type High Lift Anchor Drilling Rig

MDL-150H crawler high lift anchor drilling rig is a high-efficiency drilling rig developed by RM for anchoring, jet grouting and dewatering in subways, high-rise buildings, airports, ground source heat pumps and other deep foundation pits.

RM is a professional crawler high lift anchor drilling rig manufacturer and supplier in China. If you are interested in crawler high lift anchor drilling rig products, please contact us. We follow the principles of assured quality, conscientious price and enthusiastic service.

Main features:

1. The maximum speed of the crawler high-lift anchor drilling rig can reach 170 rpm; it has increased by 20% compared with the MDL-135H, and has considerable efficiency for twist drills and soil layers.

2. Energy saving and high efficiency: the work efficiency is effectively increased without increasing the power.

3. While the speed of the crawler high-lift anchor drilling rig increases, the torque increases by 10% compared with the MDL-135H, and the peak torque increases to 7500NM.

4. A new hydraulic system is adopted, with a simple structure, reasonable layout and humanized operation.

5. Compared with the MDL-135H drilling rig, the construction efficiency has increased by about 20%. The torque and speed can be reasonably matched according to actual needs. The propulsion frame stroke is 3.4 meters, and 3 meters of drill rod and casing composite drilling can be carried out.

The crawler high-lift anchor drilling rig can be equipped with a rotator with corresponding torque according to different formations, which increases the adaptability of the drilling rig. It is equipped with crawler chassis, high-position rotating platform, large-diameter outriggers, 0.9-meter slide, and hole support device, which makes the drilling rig easy to move and fix, and stable during drilling. It is equipped with a clamping shackle, which makes loading and unloading drill pipes and casings less labor-intensive and more efficient.

Common construction techniques:

1. Three-wing drill bit drilling, mud slag removal. Applicable to high-speed drilling in soil layers and other strata.

2. Air down-the-hole hammer drilling, air slag removal. Applicable to rock and broken layer construction.

3. Bottom-hole hydraulic hammer drilling, mud slag removal. Applicable to broken layers, sand and gravel layers and other strata with high water content.

4. Casing drilling.

5. Drill rod and casing composite drilling.

6. Single, double, triple rotary spraying, fixed spraying, swing spraying and other rotary spraying techniques.
