Mine Hydraulic Mining Drilling Vehicle
The PDR391RH is suitable for medium-length hole drilling in production roadways of 3×3 m and above. Adopting a simple and practical design concept, it features high reliability, high production efficiency and low operating costs. The PDR391RH is equipped with a high-power diesel engine, heavy-duty four-wheel drive, articulated steering chassis, and safety canopy certified to FOPS standards. The 22 kW Sandvik LD120SH hydraulic rock drill enables the drill jumbo to achieve higher and more stable penetration rates and longer tool life in different rock types. The automatic control function of the THC drilling hydraulic system ensures that the operator can focus on safe, fast and accurate drilling operations. The rational overall layout of the PDR391RH provides the jumbo with stable traveling performance and excellent operating visibility. The drill jumbo is easy to operate and maintain, with all routine maintenance accessible at ground level.
