25m Depth Down The Hole Geotechnical Hydraulic Drilling Rig For Rock Blasting drilling
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
