Applicable Range of Hole Diameters:89-140 mm
1:Being a split-type surface drill rig, HDR-A7 is widely used in mines and quarries throughoutthe country. The simple structure of the drill rig provides easy maintenance and strongmaneuverability. lt is sensitive to rock fissures, so it is particularly suitable for large-vol-ume deep hole drilling for quarrying operations.
2:The unique fan DE-dusting system driven by high-speed hydraulic motor makes theequipment comparable to a fully hydraulic crawler drill, allowing the operator to complete-ly eliminate the dust and effectively reduce the wear of the dust on the working mecha-nism of the drill rig.
3:The bi-directional control panel features ergonomic design and reasonable layout forconvenient operation. Two sets of control systems for tramming and positioning areeasy to move between the holes, providing an extensive vision. The rear control panelof the drill rig allows the operator to stand on the machine during the relocating or longdistance tramming, and therefore effectively reduces the labor intensity, improves workefficiency and ensures personnel safety.
