SA-150Q Crawler Anchoring Drilling Machine Main features:

1. Our anchor drilling machine is with full hydraulic control, easy and flexible operation, convenient shifting, good maneuverability, saving time and effort.

2. Anchor drilling rig’s rotary control panel can be closer to the working orifice, making it easier to observe the orifice condition.

3. The rotor of the anchor engineering drilling rig is driven by dual hydraulic motors, with large output torque and a lower center of rotation than similar products, which greatly improves the stability of the anchor drill machine.

4. The new angle-changing mechanism makes hole alignment more convenient, the adjustment range is enlarged, and the requirements on the working surface can be reduced.

5. According to the customer’s local special working conditions, the heat dissipation system has been optimized to ensure that the maximum temperature of the hydraulic system does not exceed 70°C when the outdoor temperature is 45°C.

6. This anchoring drilling rig can be used with special pipe-following drilling tools (drill pipe, casing, eccentric drill bit, etc.) to open holes in unstable formations with casing wall protection and conventional ball-tooth drill bits for final holes. The drilling efficiency is high and the hole quality is good.

7. The anchor drilling rig is mainly suitable for anchoring and supporting deep foundation pits. It can also be used for rotary grouting construction by replacing the rotary grouting module.

8. In addition to the crawler chassis, clamping shackle and turntable of the SA-150Q anchor drilling machine, we also provide users with optional accessories such as rotary spray modules. Users can add options when ordering the anchor drilling rig to make our anchor drill rigs more suitable for your engineering projects.
