The KG310/KG310H down the hole drill rig for open use is an improved device in compliance with national regulations on environmental protection. Equipped with the Yuchai double-cylinder engine (China III), the drill rig meets the national standards for emissions and environment. The flexible derricking mechanism is suitably qualified for horizontal drilling at a low level.
The hydraulic system has been improved, leading to increased system flow and rotary speed. Moreover, the hydraulic cylinder has been optimized, thus making it more reliable; and the additional ring (plate) makes handling and lifting easier.
The KG310H down the hole drill rig for open use is equipped with a dust collector, thus making operation more environment-friendly and reliable.
