Project Background and Operational Constraints
The client, a prominent general contractor in Riyadh, Saudi Arabia, was undertaking a large-scale open-pit mining and deep foundation infrastructure network development. The project site is characterized by typical desert hard rock geology (predominantly hard limestone and granite blocks with a hardness rating of f=8 to f=12).
The primary challenges involved drilling deep blast holes and water borewells with a diameter of φ115mm-φ130mm up to a depth of 50 meters under severe conditions:
- Extreme High Temperature: Desert daytime temperatures frequently exceed 45°C, creating massive heat dissipation stress on the hydraulic systems.
- Strict Drilling Efficiency Requirements: The tight project schedule required a reliable dth rig machine capable of maintaining a drilling speed of at least 1.5 meters per minute without frequent auxiliary maintenance.
- Complex Topography: Moving the rig over loose sand and steep rock slopes required superior off-road climbing capabilities and chassis durability.
Why the Client Chose YG DTH Drilling Rig Solution
Instead of making a hasty purchase based purely on initial market assumptions or a generic online search, the client followed a strict, data-driven procurement logic based on rigorous field matching. They compared multiple international engineering brands before choosing YG DTH borewell machine.
- Torque & Speed Optimization: The client’s engineers prioritized rotation torque over generic marketing descriptions. Our equipment delivers a massive rotation torque of 0-3500 N.m and a speed of 0-170 rpm, perfectly overcoming the high friction resistance encountered during hard rock drilling.
- True Versatility in Multi-Angle Operations: The site required both vertical water borewell drilling and horizontal or inclined blasting holes. Our rig supports multi-angle adjustments, allowing the guide rail to tilt seamlessly while keeping the heavy-duty crawler steady, ensuring absolute structural safety.
- Optimized Energy Consumption: With an excellent fuel economy of only 0.38L per meter drilled, the rig drastically reduces long-term operational overhead, addressing a hidden cost factor that many buyers overlook until after deployment.

YG DTH Borewell Machine Matching Desert Hard Rock Geology
To fully adapt the heavy equipment to the unique environment of Saudi Arabia, several engineered adjustments were implemented:
- Chassis and Track Upgrade: Standard low-cost channel steel rails and cast track plates lack the durability for harsh desert terrains. YG equipped this machine with an upgraded reinforced crawler chassis, heavy-duty track frames, and high-torque reduction motors, maximizing climbing capability and extending track lifespan on abrasive rock.
- Dual-Power System Optimization: To combat local power limitations, the rig can be ordered in either an eco-friendly electric-pneumatic linked configuration or a fully autonomous diesel-powered layout paired with high-capacity air compressors, ensuring standard operational output even in zero-grid mountain zones.
- Ergonomic and Protected Control Station: The central control console was optimized with an integrated protective casing, safeguarding the core control valves from fine desert sand and accidental impacts.
Delivery & On-site Usage Feedback
YG completed the production, debugging and transportation of the equipment within the agreed time, and delivered the DTH borewell machine to the client’s construction site in Saudi Arabia on schedule.
After 3 months of continuous on-site operation, the equipment has achieved excellent construction results: the cumulative drilling depth exceeded 2000 meters, the drilling diameter range of 90-165mm fully covered the client’s construction needs, the equipment failure rate was less than 1%, and the drilling efficiency was 30% higher than the client’s previously used equipment. The client highly recognized the performance of our DTH borewell machine and our full-process service, and has signed a follow-up equipment procurement intention with us.
