product Introduction
KQDT-125 is a compact down-the-hole (DTH) drilling rig designed for drilling large ,long and downward holes with high demands on hole straightness in mining. It is suitable for drifts with a cross-section ranging from 3.3 to 4 m and can be effectively applied in sublevel stoping mining method. The drilling rig comes with a rotatable beam, a DTH hammer, and four-wheel-drive, enabling flexible operation in confined underground spaces.

- 1.Drilling System Equipped with a hydraulic stabilizer mechanism, the drill beam ensures hole deviation of ≤1%, suitable for drilling holes with diameters of 120–254 mm and depths up to 100 m, ensuring precise and stability. The drill beam can rotate 360°and tilts from -10°to 55°, enabling multi-angle drilling. The rotary head features stepless speed control, allowing operators to adjust drilling speed according to varying rock hardness, which greatly enhances efficiency and adaptability.
- 2.Robust Chassis The four-wheel drive system enables 360° on-the-spot steering. For long-distance tramming, the brakes can be released so it can be towed by other vehicles, ensuring fast and efficient operation. Equipped with lifting outriggers and a rear swing axle to improve operational stability.
- 3.Remote Control System Equipped with an advanced remote-control system, it enables precise control of tramming and drilling operations from a distance, significantly enhancing operational safety. Even in hazardous or dusty environments, operators can stay at a safe distance to reduce risks.
- 4.Flushing System The rig features a high-efficiency flushing system that enables operators to quickly clear dirt, dust, and debris from the machine. Regular flushing helps prevent residue buildup that could cause wear or blockages, thereby extending service life, lowering maintenance costs, and ensuring long-term reliable operation.

Application
The KQDT-125 is a tire-mounted down-the-hole (DH) drilling rig for mining. It operates with a 380V voltage rating and uses a down-the-hole impactor. It features a closed four-wheel drive hydraulic system and is suitable for drilling annular holes in underground mining areas at depths of 3.3-4m. It is a dedicated drilling equipment and can also be used for excavation and mining operations in both overhead and inclined sections.
