Product Description

High technology reverse circulation RC drill for geological exploration/Hydraulic RC coring drill

RC drill rig is a new multifunction crawler type rig which is high efficient and environment friendly. It adopts the most advanced foreign reverse 
circulation drilling technology, the drilling dust can be effectively collected by the dust collector, which avoid the environment pollution. 
A cyclone is equipped to collect sample for geological analysis. It is the ideal equipment for the geological exploration hole, water well, 
monitoring well, ground source thermal pump conditioning hole and other deep holes. 
This drill rig is powered by the air compressor, it can work in different ground formations. The mast motions like lifting and adjusting, 
rod loading/unloading, rotary and forwarding, the jacks and winches are all controlled by the hydraulic system, which reduces 
the labour intensity and improves the working efficiency and quality.
