A7 is a split open-pit DTH drill, widely used in mines and quarries throughout the country.
The drill has simple structure, convenient maintenance, strong mobility, and is not sensitive to
rock fracture. It is especially suitable for large-scale deep-hole drilling and quarrying.
Its unique high-speed hydraulic motor-driven fan dust removal system can be comparable to the
full hydraulic crawler drilling rig, so that operators completely free from dust, effectively reduce
the dust on the working mechanism of the drilling rig wear.
Two-way control panel adopts ergonomics design, reasonable layout, easy to operate,
walking and positioning two sets of control system to facilitate the movement between holes, wide
vision. The rear control panel of drilling rig is convenient for the operator to stand on the machine
during the transition or long distance walking, which effectively reduces the labor intensity,
improves the work efficiency and ensures the safety of personnel.
