Built with a rugged crawler undercarriage for rough job site travel, a crawler DTH drilling rig is a dedicated open-pit drilling machine engineered to drill blasting holes across mining, railway, water conservancy, and earthwork construction projects. This dth drilling machine splits into two mainstream configurations: split-type units paired with wheel-mounted air compressors, and all-in-one models that integrate air compressor systems directly on the chassis. Operators pick configurations based on site road conditions and on-site power layout demands.
All popular models in our lineup deliver drilling diameters ranging from 83mm up to 165mm, and support both vertical downward drilling and horizontal hole boring, with maximum horizontal drilling height reaching 3.6m for the largest variant. The maximum practical drilling depth stays within 50m, which fits standard blasting work for most quarry and infrastructure projects perfectly.

Core Applications of Crawler DTH Drilling Rig
- Open Pit Mining & Quarry Operation: Quarry operators use the tracked unit to drill regular blasting holes for rock excavation. Its flexible travel performance lets crews shift drilling positions quickly across expanding mining zones without extra site paving work.
- Railway and Hydraulic Engineering Construction: During mountain railway tunnel preliminary work and reservoir slope reinforcement projects, the down hole drilling equipment completes pre-blasting hole drilling on steep slopes and uneven mountain surfaces that wheeled drilling machinery cannot reach.
- Municipal and National Defense Earthwork Projects: For land development, foundation blasting, and coastal reef blasting tasks, the machine adapts to both inland soil-rock mixed ground and nearshore construction environments to finish preset drilling tasks efficiently.
- Demolition and Site Preparation Work: Large-scale building relocation projects rely on the rig to drill pre-split blasting holes for controlled rock breaking, which reduces vibration impact on surrounding existing structures.
4 Advantages of YG Crawler DTH Drilling Rig
- Fast Site Transition Efficiency: Crawler travel structure delivers steady movement speed from 2.2km/h to 4km/h across different models. Crews relocate the rig between drilling spots rapidly without repeated disassembly, cutting idle downtime heavily between different working zones.
- Diversified Model Specifications For Tiered Demands: Our product line covers total machine weight from 3.8T compact units up to 8T heavy-duty models. Small lightweight versions suit narrow mountain construction sites, while heavier high-power units tackle high-volume daily quarry blasting work. Fuel tank capacity ranges from 70L to 225L to match different daily operation durations.
- Flexible Drilling Angle Adaptability: The rig performs standard vertical blasthole drilling for quarry mining, and also switches to horizontal drilling mode for slope anchor holes and side rock pre-split work. Adjustable horizontal drilling height from 2.8m to 3.6m covers most common side rock construction height requirements.
- Two Configurations For Different Site Conditions: Clients select split setups if the job site already has independent air compressor equipment to control overall setup cost, or choose integrated all-in-one units for remote sites with no fixed air supply layout, cutting extra auxiliary equipment deployment work.
Crawler DTH Drilling Rig Site Safety Design Highlights
Each crawler DTH drilling rig incorporates multi-layer built-in safety designs to reduce hidden hazards during all-day blasting drilling operations, a critical detail valued by mine and construction site management teams worldwide.
- First, the crawler walking system equips stable anti-slip track treads to prevent side slip when traveling on wet, loose mountain slopes or uneven blasted rock piles, avoiding dangerous rig tipping accidents during position relocation.
- Second, the drill mast locks into fixed vertical or horizontal working angles with mechanical positioning latches. The lock structure stops unexpected mast swing caused by rock vibration during penetration, maintaining stable hole precision and protecting on-site operators from falling drill rod risks.
- Third, the engine and hydraulic system install overheat protection sensors. If continuous heavy rock drilling pushes temperature beyond safe thresholds, the rig automatically lowers drilling feed speed to prevent engine or hydraulic component burnout during unattended long shifts.
- Fourth, all core pipeline joints adopt anti-loosening fastening structures. Compressed air and oil pipelines stay tightly connected under frequent vibration, eliminating sudden pressure drops that weaken the dth drilling machine’s drilling power mid-operation.
Every safety component undergoes strict load and vibration testing during factory assembly, so the down hole drilling equipment meets international open-pit construction safety standards for long-term heavy-duty use across global mining projects.
