Kaishan Drilling Machine Best-selling Model Kg726III for Coal Mine
The KG726III/KG726HIII down-the-hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai engine(China III), the drill rig meets nationally. standards for emissions and the environment. The tramming motor of plunger piston and four-wheel drive improve the working pressure and climbing capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position use. Meanwhile, the hydraulic system is improved, thereby proving increased system flow and rotary speed. The hydraulic cylinder has been optimized, thus making it more reliable. The guide rail is installed in an inclined way, making operations and observations easier. The thickened profile is used for the housing, and the additional ring makes handing and lifting convenient.
The KG726HIII down-the-hole drill rig for open use is equipped with a dust collector, thus making the operation more environment-friendly and reliable.
-- Safe and stable traveling system
With a low gravity center and big ground clearance, this drill machine can easily travel on bumpy roads. It is driven by a special wheel motor which brings strong grade-ability and a low failure rate.
-- Powerful and reliable engine
Adopt a famous 4-cylinder diesel engine as the driving force which has the advantages of large power, small volume, small vibration, and reliable operation.

- Powerful feed mechanism and rotating system
Optimally designed luffing mechanism and round drilling boom with the advantages of neoteric structure and easy maintenance greatly improves the drilling hole's coverage area. That also makes low-order horizontal hole drilling available.
-- Lastest designed Drilling Boom, Multi-angle operation
This rotating system is composed of an orbit hydraulic motor and planetary gearbox.
That provides the crawler rock drill, a type of wagon drill, with strong torque reserve and reduces the sticking drilling rate.
