HW-UJ21M Underground Jumbo Drilling Machine


  • Widely used in large and medium-sized tunnel anchor construction and small piping, advanced support and other construction reinforcement, its well-designed appearance, configuration, system control and so on will provide customers with better quality anchor construction reinforcement experience.

  • Innovative design, one-time positioning for variety of construction and job needs,namely drilling, anchor, injection and drilling. The perfect integration of drilling, injection and anchor into one complete machine, high mechanization, less labor intensity, less manpower.

  • Grouting and mixing one-piece body layout design, high efficient flexible jobsite transfer. Data monitoring system, used for the construction of slurry water-cement ratio and single-hole grouting data monitoring and download.

  • One boom and one working platform design for the machine with more functions, in addition to the main working boom to achieve the integration of drilling, injection and anchoring, the service working platform used for survey,anchor supply, assisting anchoring, grouting,scaling,etc.,truly one machine for multi-purposes.
