Crawler Deep Foundation Pit Anchor Drilling Rig

The MDL-150D crawler deep foundation pit anchoring drill rig is a high-efficiency drill developed by RM based on anchoring, jet grouting, and precipitation for subways, high-rise buildings, airports, ground source heat pumps and other deep foundation pits.

Every request from the customer will be responded to within 24 hours. RM will provide you with the best after-sales service and timely delivery.

Main features:

1. The maximum speed can reach 170 rpm; it is 20% higher than that of MDL-135D, and it is very efficient 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 increases, the torque increases by 10% compared with MDL-135D, and the peak torque increases to 7500NM.

4. It adopts a new hydraulic system with simple structure, reasonable layout and user-friendly operation.

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

The crawler deep foundation pit anchoring drill can be equipped with a slewing device with corresponding torque according to different strata, which increases the adaptability of the drill. It is equipped with a crawler chassis, a high-position rotating platform, a large-diameter leg oil, a 0.9-meter slide, and a hole support device, which makes the drill easy to move and fix, and stable during drilling. It is equipped with a clamping shackle, which makes loading and unloading drill rods and casings less labor-intensive and more efficient.

The crawler deep foundation pit anchor drilling rig is equipped with corresponding drilling tools, which can achieve the following construction processes:

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

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

3. Bottom-hole hydraulic hammer drilling, mud slag removal. Suitable for construction in 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 processes.
