Product Applications Product Features Technical Parameters Related Products


The KG430SH down the hole drill rig for open use is equipped with diesel engine and motor,capable of separate operations. The folding frame track and four-wheel drive are adopted;and the walking motor of plunger piston and track leveling improve the working pressure and climbing capacity. The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position.

The doublerotation motor 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 KG430SH down the hole drill rig for open use is equipped with a dust collector,thus making operation more environment-friendly and reliable.
