Product Description

Reverse circulation multifunctional drilling Machine is a new efficient, environmentally friendly, and multifunctional tracked drilling Machine.lt adopts the latest RC drilling and mining technology from abroad, and drilling dust can be effectively collected through dust collectors, avoiding environmental pollution. lt can also be collected and discharged through a cyclone separator, which can be used for sampling and analysis work in geological exploration departments.lt is the preferred equipment for geological exploration drilling and other deep holes.

This drilling Machine can use compressed air reverse circulation down-hole drilling on various formations. The lifting of the drilling Machine frame, compensation of the drilling frame/multi angle drilling unloading of the drill pipe rotation and feeding,support legs ,hoisting,walking and other movements are all achieved by the hydraulic system, greatly reducing labor intensity, improving construction efficiency and engineering quality.
