Applications of HW-190/190YY well drilling machine
HW series hydraulic drilling rig is a kind of widely used portable drill. It is suitable for drilling water well, geological survey, geological core drilling, small grouting holes, blasting holes of railway, water conservancy, bridges, dam foundation and other buildings . According to different strata, it drills by choosing diamond, composite films and alloy.
HW-190/190YY Shallow well drilling machine
a.It improves drilling efficiency and reduces labor intensity With hydraulic automatic feeding
mechanism.
b.It can be achieved without stopping to change rods, easy to operate, safe and reliable with
ball clip holding mechanism or hydraulic chuck.
c. It has hole bottom pressure gauge to be easy to master the situation in the hole.
d. It also has advantage of Compact structure, concentrated handle, small footprint, light weight, strong decomposition, easy to move. It can be operated in plains and mountain areas.
