Restricted-Access Ground Anchor Drill Rig
The Restricted-Access Ground Anchor Drill Rig is engineered for ground anchor drilling where limited headroom, narrow access routes, or restricted working positions dictate equipment selection. Typical applications include basement excavation support, retaining walls, foundation reinforcement, and specialized slope stabilization projects. The optimal configuration is determined by access dimensions, drilling angles, borehole diameters, depth, ground conditions, and the specified drilling method.
Key Advantages
Compact Access Planning: Transport dimensions and operating dimensions are evaluated separately to ensure the rig can successfully navigate to the work area and complete required drilling movements.
Controlled Drill Positioning: Mast geometry, feed travel, and drilling angles are precisely matched to the target hole location and available working clearance.
Matched Drilling Capacity: Rotary torque, feed force, drill rod dimensions, and tooling are configured against the specific borehole design and geological conditions.
Project-Specific Configuration: Machine layout, drilling components, and auxiliary equipment can be reviewed and aligned with project requirements and technical limits.
Applications
Excavation Support: Drilling anchor holes along retaining structures for engineered deep-excavation support systems.
Foundation Reinforcement: Ground anchor drilling for foundation strengthening and related geotechnical construction.
Retaining Walls: Drilling at specified positions and inclinations in accordance with structural drawings and site clearance requirements.
Slope Stabilization: Anchor-hole drilling for slope reinforcement where access, platform conditions, and equipment positioning are suitable.
Confined Construction Areas: Selected basement and urban construction projects where transport access and operating clearance require detailed assessment.

Configuration Options
Mast and Feed System: Confirm mast arrangement, feed stroke, working height, and drilling-angle range against your site layout.
Power and Hydraulic System: Specify the power source, rated output, hydraulic flow, and operating pressure according to your selected configuration.
Drilling Tools: Match drill rods, bits, casing, and flushing equipment to your geological profile and required borehole dimensions.
Customized Equipment: Configuration changes can be reviewed for access dimensions, drilling orientation, and operating requirements, subject to structural design and system compatibility.
Restricted-Access Site Assessment
To ensure proper equipment selection, please review the following site parameters prior to project planning:
Access Route: Measure the narrowest passage, lowest overhead clearance, doorway width, turning space, and transport route.
Operating Envelope: Check available clearance throughout mast movement, feed travel, drill rod handling, and drilling operations.
Ground Conditions: Assess geological information, expected soil or rock layers, groundwater conditions, and intended drilling methods.
Working Platform: Confirm platform dimensions, ground-bearing capacity, machine support requirements, and space for auxiliary equipment and drill rods.
Manufacturing and Quality Control
Assembly Verification: Each machine assembly is checked against approved drawings, configuration records, and applicable component specifications.
Functional Testing: Rigorous inspection of startup, hydraulic response, rotation, feed movement, and control functions is conducted according to standard machine test procedures.
Pre-Dispatch Inspection: We verify machine identification, ordered configuration, supplied accessories, inspection records, and shipping documentation prior to dispatch.

Frequently Asked Questions
Q: Can the rig enter a basement or narrow access route?
A: Suitability depends on transport dimensions, overhead clearance, turning space, and the complete route to the working position. We recommend confirming actual site measurements before final selection.
Q: Which specifications determine model selection?
A: The main inputs are access width and height, borehole diameter and depth, drilling angle, geological conditions, and available working space.
Q: Can the rig be customized?
A: Yes. Configuration options can be reviewed against your specific project requirements, subject to the selected machine platform and technical feasibility.
Q: Can the rig drill in different ground conditions?
A: Tooling and drilling methods must be matched to the geological profile, rock strength, groundwater conditions, and borehole design.
Q: Which documents should be confirmed before dispatch?
A: The final specification sheet, configuration list, inspection records, operating manual, packing list, and agreed shipping documents.
