KGH8 High Pressure Eco-Friendly Crawler Drilling Rig
Product Features
The KGH8 high pressure eco-friendly crawler drilling rig is a self-propelled hydraulic drilling equipment developed according to the needs of mining project using advanced hydraulic technology. The open-air DTH drill is easy and convenient to operate and provides a stable performance. The configuration of hydraulic components can be adjusted for different boring applications. A high-power four-cylinder Cummins engine is used for high-altitude drilling, and a large rotary torque reducer meets the demand for larger and deeper drilling operations. The drilling rig is ideal for open pit mining, road construction, tunnel excavation and other engineering. Equipped with a dust collector and purifier, drilling operations won’t pollute the environment.
