Product Introduction
The Rail Type Rock Drilling Machine is a highly efficient drilling device powered by compressed air. Equipped with a proven pneumatic impact mechanism and a gear-reduction rotation system, it offers excellent maneuverability within confined spaces. During operation, parameters can be flexibly adjusted to suit specific rock conditions; consequently, the Rail-Type Rock Drilling Machine is particularly well-suited for side-hole drilling applications in tunneling operations.

Product Advantages
High Drilling Efficiency and Flexible Parameter Adjustment
The impact and rotation systems are independently controlled, allowing for separate adjustment of impact power and rotational speed based on rock hardness. This ensures optimal matching for various working conditions, thereby effectively increasing drilling speed.
Compact Structure and Strong Spatial Adaptability
With a vertical clearance of only 80 mm from the drill rod center to the machine's top, the unit features a compact profile. This enables flexible drilling of lateral and horizontal holes within narrow cross-sections-such as tunnel sidewalls and culverts-reaching locations that are inaccessible to standard drilling rigs.
Economical Energy Consumption and Stable, Reliable Operation
The Rail Type Rock Drilling Machine utilizes a valveless air distribution impact system, which maximizes the utilization of compressed air expansion energy to achieve lower air consumption compared to standard rigs operating on the same air supply. Furthermore, the inclusion of a damping piston starting mechanism reduces start-up shock, thereby extending the overall service life of the machine.
Applications
Underground Medium-to-Deep Hole Mining
Suitable for stope operations in metal mines, non-metal mines, and coal mines. It is capable of drilling upward-facing fan-shaped or ring-patterned blast holes of medium-to-deep depth-reaching effective depths of up to several tens of meters-thereby meeting the demands of large-scale mining operations.
Tunneling and Underground Engineering Excavation
Widely used in the excavation and construction of railway, highway, and subway tunnels. It excels particularly in drilling lateral and horizontal holes; its compact body design ensures flexible operation even within limited spatial environments.
Quarrying and Hard Rock Drilling
Demonstrates stable performance in the blast mining of hard rock materials such as granite and limestone. When paired with a drill frame, it enables continuous drilling operations, helping to boost quarrying efficiency and reduce overall operational costs.
Quality Control
System Assurance: We operate in accordance with ISO 9001 standards; written procedures are established for every stage-including design, procurement, and production-and we undergo annual third-party audits.
Process Control: We inspect materials when they come in. We check their hardness and size. During assembly we do inspections. We check things, like fit clearances. This ensures that units that don't meet our standards don't move on to the stage.
Final Inspection: We test every rock drill on a stand. We measure how often it hits, how air it uses and how much it twists. We only release units that work well and keep records of our inspections.
