KG420SH Affordable Mining Blasting Hole Drill/Crawler DTH Surface Blast Hole Drill/Drilling Rig

Application

The KG420S down the hole drill rig mine drilling rig for open use is an improved device in compliance with national regulations in diesel-engine emissions. Equipped with Yuchai four-cylinder engine (China 3), the drill rig meets national standards for emissions and environment. The folding frame track, four-wheel drive and tramming motor of plunger piston improve the working pressure and climbing capacity, the expanded pith and lifting-arm hydraulic cylinder enable it to meet the requirements on extreme position.The double-motor rotation increases the rotary torque and revolving speed; and the lifting hydraulic cylinder and chain are expanded to promote the lifting force and reliability. The thickened profile folder is used for the housing, thus improving its level of intensity and rigidity, and the additional ring makes handling and lifting convenient.

The KG420SH down the hole mine drilling rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.

Characteristics

DTH Mining Drilling Rig

1.Turn-around machine. The structure of newly designed planetary reduction box is more compact than that of straight tooth type reducer with greater reduction ratio, more efficient torque moment transmission, and more smooth operation.
2. Maintenance-free propulsion mechanism. Belongs to a new generation of products,it applied more advanced technology, the propulsion mechanism doesn't need routine oil maintenance.
3. Maintenance-free chassis. Enhanced engineering machinery crawler & box structure crawler frame are sturdy and durable; Maintenance-free thrust wheels, no need for oil injection.
4. Control console. Centralized control console provides convenient operational control of drilling rig; Fast propulsive and lifting operation reduce the auxiliary time and enhance the working efficiency.
5. Drive device.Yuchai 70KW turbocharged engine (Cummins optional) is featured by the strong power and easy maintenance.
6. Drilling arm .Multi-angle elongate functional drilling arm drills larger scope,its sectorial area of drilling work extends 20% .
