KQZDX Series Crawler Type Air-hydraulic Linkage Down-the-hole Drilling Rig

The KQZDX series crawler-type pneumatic-hydraulic down-the-hole (DTH) drilling rig is a highly efficient and flexible compact open-pit crawler rock drilling equipment. It utilizes compressed air to drive the impactor, generating a high-frequency impact force on the drill bit, while a hydraulic motor drives the bit to rotate at high speeds to achieve highly efficient rock crushing.

This drilling rig is highly adaptable to a wide range of rock strata, from soft rock to extremely hard rock. It is primarily applied in fields such as open-pit mine blasting holes, large-scale stone engineering, and water conservancy and hydropower construction.

Key Features of the KQZDX Series Crawler-Type Pneumatic-Hydraulic DTH Drilling Rig

Self-Propelled Mobility: Equipped with a crawler-type travel chassis, it eliminates the need for manual moving, making transport and repositioning significantly more convenient.

High Efficiency: The drilling rig utilizes hydraulic cylinders for both propulsion and lifting, which drastically enhances overall operational efficiency.

Multi-Angle Drilling: The angle of the drilling mast is fully adjustable, enabling versatile multi-angle drilling construction ranging from 35° to 90°.

Versatile Power Head: The power head is capable of forward rotation, reverse rotation, and inching (micro-movement) to meet a wide variety of demanding construction requirements.

User-Friendly Operation: Featuring a straightforward structural design, the drilling equipment is easy to learn. Novice operators can get up to speed quickly, thereby reducing reliance on intensive manual labor.

Durable & Cost-Effective: Built with high-strength materials, the rig offers excellent wear resistance and impact resistance, effectively lowering maintenance and component replacement costs.
