Diesel down the Hole Hammer Blast for Open Use in Water Wells KT5J

With Reliable Motor, The KT5J Integrated down the hole drill rig for open use is an advanced drilling device integrating the down the hole drilling system and screw air compressor system, characterized by compact structure, excellent integrity and mobility.
Equipped with the Yuchai China stage III Engine, the drill rig meets national standards for emissions and environment. It is typical of energy conservation, efficiency, safety, environment-friendliness, flexibility, simple operation and stable performance, etc.
Powerful Rotary Head, Cycloid rotation double motor for powerful rotation torque. Bigger and stronger designed rotation head for smooth high torque output and less drill tool jamming with seamless speed regulation.


Hydraulic System, The hydraulic system is upgraded,the hydraulic cylinder is more reliable,the system flow is increased,and the rotary drilling speed is increased. Enlarged Dry Type Dust Collector, KT5J is with Dust Collector. It is Hydraulic Cyclonic Laminar Flow.Reduce dust and protect workers health. Reduce air pollution and protect the atmospheric environment.
Control Panel, All controls integrated on the control panel for convenient operation by single operator, higher work efficiency and lower drilling cost,safer and more comfortable operation.
Walking Hydraulic Motor, Dual-speed tramming plunger hydraulic motor.Low noise, high efficiency, long service-life, high power, easy maintenance.
Construction Steel Crawler, Equipped with speed reduction tramming system and standard excavator track for compact structure. Excellent off-road performance with powerful two-speed hydraulic tramming system for extreme low failure rate.
