MDL-C200 -double pipe drilling machine

1.MDL-200 is applicable to a wide-range of strata with big torque, high rotary speed, and big power.When meeting those fragile holes such as sand gravel layer, gravel layer, sand stone soil, sand hole, the top drive drill equipment has a very high penetration rate and drilling efficiency. Especially when the moisture content of local layer is too high to use DTH hammer when work, this top head drive drill rig is the only choice. 3.This top head drive drill rig adopts variable hydraulic system and can with big power without DTH hammer or air compressor.The drilling tools from the outer to the inner and all involved in the transmission of the impact power, it is not easy to happen the hole accidents such as drill sticking. 4.This top drive drill equipment is applicable to anchor hole, such as urban foundation pit supporting . And is mainly applied to construction engineering supporting, slope supporting,all kinds of guide hole, tunnel and pipe shed engineering,etc.
