Crawler Double-arm Tunneling Jumbo
The self-developed NMJ2-25 crawler double-arm tunneling jumbo is used for blasting holes and bolt holes in tunnels and tunnels in coal mines and metal mines. Workers stand in a safe place to operate a mechanical arm for rock drilling. This equipment replaces the previous manual hand-held air gun drilling operation, reducing the work intensity of workers, improving work efficiency and safety factor. Suitable for section (width x height) 3.Om x3.0m to 5.9mx4.3m. Climbing ≤14°, walking speed up to 2.4km/h. The working mechanism of the machine adopts full hydraulic drive, and the rock drilling speed can reach 0.8-2m/min. The working mechanism of this machine adopts full hydraulic drive, which is flexible and fast in rock drilling speed; advanced hydraulic system, convenient maintenance; stable work and climbing ability Strong, easy to operate, safe and reliable.
Advantages
Advanced, user-friendly control system
Automatic boom movements, pre-planned drilling patterns and data collection offer productivity control
Noise and vibration-insulated cabin offers comfort and excellent visibility
RD525 series rock drills deliver superior performance with high consumable life
Dynamic correcting redirects drilling during boom movement and helps keeping the hole bottom in place
Lock-to-target: Helps finding the hole position quickly and accurately
