The Full Hydraulic Multifunctional Crawler Anchor Drilling Rig

The full hydraulic multifunctional crawler anchor drilling rig is a highly efficient engineering machine specially designed for foundation reinforcement and challenging geological conditions. Featuring full hydraulic drive and a crawler chassis, this rig offers excellent maneuverability and multi-process adaptability, meeting the requirements of various foundation treatment and support construction projects.

Detachable 10-Meter Auxiliary Mast

• The auxiliary mast can replace elevated jet grouting during jet grouting processes, significantly reducing the number of drill rod disassemblies, improving efficiency, minimizing material waste, and lowering quality risks.
• During anti-uplift anchor construction, anchors can be hoisted directly, eliminating the need for additional lifting equipment and saving construction costs.
• The auxiliary mast can be detached as needed for different processes, facilitating the switch to inclined anchor cable operations and other methods without affecting the main functions of the rig.
• For short anchor rod construction, a single rod can be driven in one go, greatly saving labor and time.

Large Through-Hole Rotary Head

• With a through-hole diameter of 92mm, it accommodates 89mm drill rods, easily enabling triple jet grouting and various anchoring operations.
• Supports conventional 89mm steel pipes for anchoring, ensuring strong process compatibility.
• The innovative hydraulic chuck structure allows for convenient and flexible tool changes without frequent replacement of transition joints.
• The high-torque power head, combined with our company’s reinforced jet grouting tools, allows for direct jet grouting in most strata without pre-drilling, significantly saving costs and time.

Crawler Chassis

The rig adopts a crawler chassis with high ground pressure ratio, ensuring stable movement even on soft and complex ground conditions.

Orifice Guide Device

• Facilitates easy tool removal during jet grouting processes, ensuring correct drilling angles and verticality.
• Enhances the force-bearing performance of steel pipes during rod laying, improving construction accuracy.
• The rotating mechanism at the orifice effectively reduces tool wear and extends service life.

Application Fields

The full hydraulic multifunctional crawler anchor drilling rig is widely used in soft soil foundation treatment, waterproof curtain construction, and pilot hole drilling. Its outstanding versatility and adaptability make it an excellent choice for foundation reinforcement, support construction, and underground engineering. Whether in municipal, transportation, or large-scale geological disaster management projects, it can efficiently handle various drilling tasks.
