Audited Supplier G7 Full Hydraulic Open Air Top Hammer Drilling Rig
G7 is a split open-pit DTH drill rig, which is widely used in mines and quarries all over the country. The drilling rig has simple structure, convenient maintenance, strong maneuverability, and is not sensitive to rock fissures. It is especially suitable for large-volume deep-hole drilling and quarrying operations. Its unique high-speed hydraulic motor-driven fan dust removal system is comparable to full hydraulic crawler drilling rigs, allowing operators to completely get rid of dust and at the same time effectively slowing down the wear and tear of the drilling rig's working mechanism.
1. Simple operation
The intuitive control system adopts a combination of handles and buttons for operation. The cab has a wide field of vision, and the process of drilling, loading and unloading rods is clear at a glance, and the process is controllable.
2. Convenient maintenance
The layout of the tubing is reasonable, and each tubing in the reel is in the corresponding guide groove, which avoids the mutual friction between the tubing and improves the service life of the tubing. Both ends of the tubing and cable are equipped with marking rings for easy maintenance.
3. Economy
The engine meets the new emission requirements specified by Tier/Stage3. It integrates an air compressor and an automatic lever changer, and can be operated by a single person. The compact structure and high-efficiency system save fuel consumption compared to split machines.
