The biggest advantage of the down-the-hole drilling rig is that in the process of rock drilling, the impactor dives into the hole to reduce the energy loss caused by the impact energy transmitted by the drill pipe, thereby reducing the impact of the hole depth on the rock drilling efficiency. The down-the-hole drilling rig is equipped with an air compressor, which greatly improves the work efficiency.



Main feature:
1. It can be a tracked self-propelled chassis or a vehicle-mounted self-propelled chassis.
2. The rig is equipped with dry dust collector, drill pipe changer, and adopts the most advanced design and layout.
3. Robust yet compact design provides it with better manoeuvrability in tight corners and higher spacing – burden range.
Due to the continuous update and progress of technology, the difference between the technical parameters and configuration and the actual product is subject to the actual delivery.

DXL920 Separated DTH Surface Drill Rig
Professional Surface Drilling Equipment For High-Efficiency Rock Drilling

The DXL920 Separated DTH Surface Drill Rig is engineered to deliver reliable and efficient drilling performance for today's demanding mining, quarrying, and construction industries. Combining advanced Down-The-Hole (DTH) drilling technology with a robust crawler platform and intelligent hydraulic control system, the DXL920 is designed to maximize productivity while minimizing operating costs.

Surface drilling projects require equipment capable of producing accurate blast holes under challenging geological conditions. The DXL920 achieves this through its powerful rotary drive, efficient feed system, durable boom structure, and stable hydraulic performance. Whether drilling in granite, basalt, limestone, marble, or other hard rock formations, the machine maintains excellent penetration rates and drilling accuracy.

The separated configuration allows the drilling rig and air compressor to operate independently, offering greater flexibility for transportation, maintenance, and equipment matching. Contractors can select compressors based on specific project requirements, improving utilization while reducing ownership costs.

The DXL920 is widely used in open-pit mines, aggregate quarries, road construction, railway projects, hydropower developments, municipal engineering, and infrastructure construction projects around the world.
