QDGL-2B anchor drilling rig is used for urban construction, mining and multiple purpose, including side slope support bolt to deep foundation, motorway, railway, reservoir and dam construction. To consolidate underground tunnel, casting, pipe roof construction, and pre-stress force construction to large scale bridge. Replace foundation for ancient building. Work for mine exploding hole.
QDGL-2B anchor drilling rig is used for basic construction, to complete following missions. Such as anchor, dry powder, mud injection, exploration holes and small pile holes missions. This product can complete screw spinning, DTH hammer and scraping drilling.
The additional casing makes the appearance of the machine more scientific, and also protects the key hydraulic parts from pollution.
Not only to protect the cylinder from damage, but also enhance the support strength.
Split console, make the operation more simple, avoid misoperation.
Longer and stronger track, effectively prevent subsidence, adapt to a wider range of strata.
Adjustable orifice height, no longer dependent on the height of the working face.
No manual labor, easier and more convenient.
Through hole high pressure resistant Faucet: the necessary device for expanding head construction.
The rotary device of the drilling rig is driven by double hydraulic motors, with large output torque and low rotary speed compared with similar products, which greatly improves the balance of drilling. Equipped with expansion joint, the life of drill pipe thread can be greatly extended.
The heat dissipation system is optimized according to the local special conditions of customers to ensure that the temperature of the hydraulic system does not exceed 70 ℃ when the outdoor temperature is 45 ℃.

The rig is mainly used for urban foundation pit support, controlling building displacement, geological disaster treatment, side slope support, and pre-stress force construction for large-scale bridges, highways, railways, reservoirs, and tunnels.
The QDGL-2B anchor drilling rig is highly versatile and capable of performing screw spinning, DTH (Down-the-Hole) hammer drilling, and scraping drilling operations.
The built-in clamping shackle device automatically dismantles the drill pipe and casing. This significantly reduces manual labor intensity for workers and accelerates the construction process.
The crawler chassis features a longer and stronger track design that effectively prevents subsidence in soft ground and facilitates rapid movement and precise hole alignment across diverse strata.
Yes. The rig is equipped with an optimized heat dissipation system designed to keep the hydraulic system temperature below 70°C even when outdoor working temperatures reach up to 45°C.
The power head is driven by double hydraulic motors that provide a large output torque at lower speeds for balanced drilling. It also includes an expansion joint to extend the operational life of the drill pipe threads.
