The KT20S integrated dual-power down the hole drill rig for open use is a heavy duty piece of drilling equipment developed by our company. It is fully equipped to meet the needs of large open-pit mines. Its travelling, propulsion, rotation, and angle adjustments are hydraulically driven. While it is traveling, the power stems from the diesel engine. The high air pressure screw nose and high air pressure DTH hammer help to ensure high efficiency drilling. It is equipped with a hydraulic dry dust collector and a wet dust remover is optional. The hydraulic mechanism is used to dismount the drilling rod, the floating joint protects the thread of the drilling rod, and the automatic unloading rod device to relieve labor intensity. The air conditioned cab provides a comfortable space for the operator.
