Integrated Surface DTH Drilling Rig, KT20S

Down-the-hole drill rig for open-pit mining

Integrated Surface DTH Drilling Rig, KT20S

This machine produced based on our previous experiences of rig-making. It is an extraordinary choice for operators working in large-scale open-pit mines. The drilling machine provides two options of dust collection—a wet or a dry dust collector. The rig is driven by a powerful engine that activates the interior hydraulic movement system, and its movement is driven by the diesel engine while the power of drilling comes from its motor. It is equipped with a high-pressure air end and DHT hammer, through which it can drill rocks efficiently, change angles and move smoothly. The machine is equipped with several advanced modules, such as a hydraulic dust collector that can reduce harm to environment, a hands-free hydraulic rod handling module, a floating rig joint protecting rod thread and an anti-jamming module. With these features, the machine can be operated by only one person. It also provides a cozy working environment for operators, with an air-conditioner installed in its large cab.
