Precise Operation : The telescopic drill boom is kept in parallel in all directions, and the positioning is fast and accurate. The square structure provides high strength and good shock absorption performance. Stable Construction : The drilling system has anti-jamming, anti-idle-drilling and automatic withdraw functions, which can effectively improve the drilling efficiency and reduce the loss of drilling tools. Safety Protection : The hood of the whole machine adopts full cover structure to provide safe and reliable protection. Bolting Device : With three-position integrated design, it can achieve fast switching between slit wedge anchor bolt and resin anchor bolt construction. The large-capacity drill steel storage and wire mesh hanging mechanical arm can effectively reduce labor intensity.
