Question 1

Our drill rigs are designed to cover a minimum drift size range from 1.8×1.8m to 3.5×4.5m. Some single-arm models support modular disassembly, making underground transportation easier. Different models offer significantly different working coverage ranges, allowing flexible selection according to drift width and height. This ensures efficient operation in both narrow development drifts and large-section main tunnels.

This ensures efficient operation in both narrow development drifts and large-section main tunnels.

Question 2

Our drill rigs are capable of operating on gradients ranging from 15° to 25°. They are equipped with anti-slip driving systems and optimized chassis counterweight design. Some models also feature multiple travel speed ranges (3.6-36km/h), allowing operators to adjust speed based on slope conditions. These features ensure stable movement and drilling operations on steep ramps while significantly reducing the risk of sliding.

Question 3

Our drill rigs integrate both face drilling and rock bolt drilling functions in a single machine. The drilling coverage is optimized to meet both excavation and support requirements. Some models are equipped with an automatic rod changing system, eliminating frequent manual intervention. This greatly shortens the excavation-support cycle and significantly improves overall operational efficiency.

Question 4

Our drill rigs are available with diesel-electric dual power or pure diesel power configurations. Dual-power models can operate on electric motors when a 380V external power supply is available, reducing energy consumption and emissions. When no power source is available, the diesel engine ensures continuous operation. Pure diesel models are ideal for remote underground sites with no power supply, offering maximum adaptability to different power conditions.

Question 5

Our drill rigs are powered by well-known engine brands such as Yuchai, Cummins, and Deutz, ensuring high reliability, low failure rates, and readily available spare parts. In addition, some models adopt a modular design with standardized key components, allowing quick underground disassembly and replacement. This minimizes downtime and meets the demanding maintenance requirements of confined underground environments.

Question 6

The rig chassis is constructed from high-strength steel, providing strong resistance against falling rock impacts. Some models are equipped with emergency braking systems and slope stability control to prevent slipping during travel. The electric motor system operates at 380V safe voltage, reducing the risk of electric shock. For dual-power models, electric operation in enclosed environments significantly reduces diesel exhaust emissions, protecting operator health and fully complying with underground safety regulations.
