China Zgyx 421 with Air Compressor Integrated DTH Drilling Rig

This series of integrated down the hole (DTH) surface drill rigs have the same traits of high efficiency, energy saving, and environment friendly with the automatic DTH rigs except cab and drill pipe handling system. Single power pack drives both screw air compressor and hydraulic system with power output of stagger design. Comparing with separated drills, the power output of integrated DTH rig is reduced by 30% and maintenance cost reduced by 50%. Drill rig and air compressor are integrated on board with dust collector standard reduces energy loss and raises work efficiency and mobility. Powerful hydraulic dual tramming control system makes good cross terrain adaptability. Large torque rotation motor makes anti-jamming easy and simple. Integrated control platform with wise layout and full displays bring about easy and simple and clear operation. Core hydraulic components by global famous makers ensure reliable operation.
These rigs are the best substitutes for the separated drill rigs due to excellent price to value comparison.
