An anchor drilling rig is a specialized drilling machine used to create holes for ground anchors, rock bolts, and soil nails. These anchors stabilize slopes, support retaining walls, and secure underground structures. The rig drills precise holes at controlled angles, allowing anchor cables or bars to be inserted and grouted in place.
Anchor drilling machines are widely used in anchoring projects such as hydropower stations, railways, and highway slope reinforcement. They are particularly well-suited for anchoring high-slope rock masses and are also used for constructing deep urban foundation pit support, anti-floating anchor bolts, foundation grouting reinforcement holes, and tunnel pipe support holes.

5 Applications of Anchor Drilling Rig
An anchor drilling machine serves multiple applications across the construction and infrastructure sectors.
- Slope Stabilization and Landslide Prevention: Highway and railway slopes require anchoring to prevent landslides and rock collapse. The YG series drills holes for anchor cables and rock bolts at controlled angles. The multi-angle capability allows drilling into the slope face from any position. The crawler mobility allows the rig to work on steep terrain.
- Deep Foundation Pit Support: Urban construction requires deep foundation pits for basements, parking garages, and subway stations. The pits must be supported to prevent collapse. The YG series drills holes for soil nails and ground anchors that stabilize the pit walls. The -10° to 90° angle range covers the full spectrum of foundation pit support drilling.
- Hydropower and Dam Construction: Hydropower projects require anchoring for dam foundations, spillway walls, and tunnel linings. The YG series drills anchor holes in challenging ground conditions, including rock and fractured formations. The high-torque models handle the hard rock common in hydropower construction.
- Tunnel and Underground Construction: Tunnel construction requires anchoring for roof support, face stabilization, and grouting. The YG series drills holes for rock bolts, pipe supports, and grout injection. The multi-angle capability allows drilling into the tunnel roof, walls, and face from a single position.
- Drainage Holes and Blast Holes: The machine drills drainage holes for slope stabilization and blast holes for controlled rock excavation. The 100- 250 mm hole diameter range covers most drainage and blasting applications.


5 Advantages of Anchor Drilling Rig
1. 4200-11000 N.m Torque – Power for Any Ground Condition: The YG anchor drill machine delivers torque from 4200 to 11000 N.m across three models. Higher torque means the drill bit keeps turning when it hits hard rock. The YG-MDL200’s 11000 N.m torque handles the toughest formations—granite, basalt, and heavily fractured ground—without stalling.
2. 60-220 Meter Depth – One Rig for Shallow to Deep Anchoring:The YG-MDL80 reaches 60-100 meters for light anchoring and drainage holes. The YG-MDL150 reaches 130-170 meters for medium-scale slope stabilization. The YG-MDL200 reaches 180-220 meters for deep foundation pits and hydropower anchoring. One series covers the full range of anchoring depths.
3. -10° to 90° Drilling Angle – One Position, Any Angle: The mast adjusts from -10° downward to 90° vertical. The operator changes the angle from the control panel without manually repositioning the mast. This covers the full range of anchoring applications: downward for anti-floating anchors, horizontal for soil nails, upward for slope stabilization.
4. 3400mm Slide Frame Stroke – Fewer Rod Changes, Faster Drilling: The YG-MDL150 and YG-MDL200 feature a 3400mm slide frame stroke. This allows the operator to use 3-meter or 4-meter drill rods in a single pass. Fewer rod connections mean less time spent connecting and disconnecting, and more time drilling.
5. Crawler Mobility – Moves Across Rough Terrain: The tracked undercarriage moves at 15-22 km/h across loose ground, mud, and debris. The anchor drill machine repositions without external assistance. No trailer, no crane, no waiting.


6 FAQs About YG Anchor Drilling Rig
A: The YG-MDL80 reaches 60-100 meters. The YG-MDL150 reaches 130-170 meters. The YG-MDL200 reaches 180-220 meters. The depth depends on the hole diameter and ground conditions.
