Choosing the right hydraulic crawler drilling rig determines how fast your open-pit mine, quarry, or civil engineering project reaches its monthly penetration target. Procurement teams across mining, construction, and energy sectors need equipment that combines strong torque, reliable diesel power, and smooth crawler mobility. Our newly designed multifunctional full-automatic down-the-hole drill is built to meet exactly that demand.
Engineered for Demanding Rock Formation Work
Surface drilling operations in hard rock environments require consistent rotational force and feed pressure. Our full-automatic DTH drill delivers a maximum rotation torque of 4,000 Nm and a rotation speed of 0-105 rpm, giving operators the control needed to maintain high penetration rates in challenging geological conditions.

Why This Crawler Rig Stands Out
A hydraulic crawler drilling rig must do more than move and rotate. It needs to keep working under high-load, high-vibration, and dusty conditions. The WANLI full-automatic down-the-hole drill is designed with a feed travel length of 5,300 mm and a feed extension of 1,200 mm, allowing longer drilling strokes between rod changes. The feed length of 8,570 mm gives the mast the stability required for straight, accurate holes.
The 480 L fuel tank supports extended shifts without frequent refueling, while the 15,500 kg chassis weight anchors the machine firmly during high-torque operations. Crawler mobility of 3.0 km/h enables efficient transfer between benches, reducing downtime that normally eats into daily productivity.
Application Scenarios That Fit Your Business
This rig is ideally suited for:
- Open-pit mining blast hole drilling in metal and non-metal mines
- Quarry operations for granite, marble, limestone, and aggregate extraction
- Road, railway, and hydropower infrastructure rock excavation
- Slope stabilization and anchor hole drilling
- Foundation engineering and geotechnical investigation
Whether your project involves 40 mm pilot holes, 70 mm production holes, or 120 mm large-diameter blasting holes, the machine handles all three diameters with the same stable hydraulic platform.
Quality Assurance and After-Sales Commitment
Every unit ships with a machinery test report and video outgoing inspection, giving buyers full transparency before delivery. Core components, including the engine, bearings, pump, and motor, are covered under a 1-year warranty. Our Shandong-based manufacturing facility ensures spare parts availability and responsive technical support for overseas clients.
