G7 Fully hydraulic open-air top hammer drilling rig
G7 Fully hydraulic open-air top hammer drilling rig
Applicable pore size range: 76-115 mm The G7 fully hydraulic open-air top hammer drill uses a high-power diesel engine, moving Powerful, can easily cope with the power requirements in high altitude and extreme cold conditions; Atlas Copco high power high pressure drill, with high perforation efficiency. The product is widely used in the drilling operation of earthwork excavation, quarry material extraction and slope treatment in open pit mines and construction projects.
Driver's Cab
Equipped with high-power air conditioning refrigeration system and warm air system, it can operate normally in various bad weather conditions. The handle main control mode makes the operation more convenient, plus simple and convenient, and provides a good working environment for operators, away from dust pollution.
Dynamic System
The high-power turbocharged diesel engine of national III standard provides enough power reserve for the whole vehicle, so that the drilling rig has a stronger adaptability to the harsh working environment such as high altitude and extreme cold. The screw air compressor improves the perforation efficiency while ensuring the good slag discharge effect.
Chassis System
The tracked walking chassis, equipped with a high-power two-speed hydraulic drive traction system and a hydraulic swing adjustment system, as well as a small fuselage width design, gives the rig excellent off-road performance and maneuverability.
Arm drill system
The rectangular section folding large arm structure is adopted, and the large arm action is driven by the hydraulic cylinder to ensure the flexibility and stability of the drilling arm system action. At the same time, the exquisite steering seat and propulsion beam bracket design enable the drill to drill 0.3-7.6m vertical and horizontal holes in the facade, and the drilling coverage area in the plane can reach 17 m 2.
Security System
The display can monitor and alarm the engine oil temperature and pressure, coolant temperature and water level, compressed air discharge temperature and pressure data, in addition, also equipped with battery charging indicator light and other safety devices.
Propulsion beam system
The aluminum alloy beam driven by oil cylinder and steel wire rope has a higher one With its strength and superior bending resistance, the ideal drilling stiffness is achieved, and the G7 is more stable when drilling relative to the chain-driven rock drill.
The propulsion beam is equipped with a mechanized rod changing system, and the operator can complete the rod connecting and unloading the action in the cab, reducing labor intensity, saving labor costs and improving production efficiency.
Hydraulic Drill
The high-power and high-pressure rock drill designed by Atlas Copco has high perforation efficiency, and has the functions of high and low impact, drilling logic control and automatic countercard drilling, so as to reduce the loss of drilling tools and be more adaptable to different rock conditions.
Control System
Proprogrammable logic controller system has high reliability, simple installation and convenient maintenance, powerful function expansion space, and easy fault diagnosis.
Two levels of dust collection system
The two-stage dry dust collection system can be self-cleaned online, with good dust collection effect and meet the national dust emission requirements.
