Application

The KG520 down the hole drill rig for open use is an improved device in compliance with national regulations on diesel-engine emissions.The drill rig is equipped with the two independent systems,namely diesel engine and motoe,capable of separate operations pressure and climbing capacity.

The expanded pitch and lifting-arm hydraulic cylinder enable it to meet the requirements of limiting position. The double rotation 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 KG520 down the hole drill rig for open use is equipped with a dust collector,thus making operation more environment-friendly and reliable

Characteristics

The rotary torque and revolving speed are raised;the propusion motor and chain are used to raise the
lifting force and reliability.The dust collector is enlarged to produce a better effect on dust collection.The
thickened profile folder is used for the housing,thus improving its level of intensity and rigidity;and the additional
ring makes handing and lifting convenient
