KT15 Drill Rig


The KT15 integrated open-pit DTH drill rig is a new type of rock drilling equipment carefully designed for the needs of large open-pit mines based on years of development and production of DTH rigs. The drilling rig’s walking, propulsion, rotation, and angle adjustment are all hydraulically driven, with strong power; equipped with high-pressure screw head and high-pressure pneumatic impactor, high drilling efficiency; equipped with hydraulic dry dust collector Collect dust and reduce environmental pollution; equipped with hydraulic rod reeling mechanism to remove the drill rod, floating joint to protect the thread of the drill rod, automatic rod reeling device to reduce labor intensity, air-conditioned cab to provide a comfortable working environment and automatic control to prevent jams The valve reduces the chance of stuck drilling. The drilling rig has the characteristics of good integrity, high degree of automation, good rock drilling effect, environmental protection and energy-saving, convenient operation, flexible maneuverability, and safe driving.

Features of KT15 type integrated open-air DTH drill carriage

1. The propulsion length is up to 5 meters at a time, which effectively reduces auxiliary time such as loading and unloading drill pipes and improves work efficiency;

2. Disc type automatic rod changing system, efficient and precise action, automatic rod changing drill depth up to 35 meters;

3. The swing angle of the carriage adopts an optimized luffing mechanism, with a total swing angle of 130° (right 97°, left 33° ), and the conversion between vertical holes and horizontal holes can be freely completed without changing the fulcrum; the minimum horizontal hole height is 550 ㎜, up to 4500 ;

4. Using Cummins electronic injection engine, strong power, and reliable performance;

5. Adopt the output arrangement at both ends of a single-engine, compact structure, and convenient maintenance;

6. High wind pressure and large displacement air compression system ( 22m 3 /min, 20bar ), which ensures the rapid drilling of the impactor;

7. Highly integrated control system, friendly control interface, one person can freely control the whole machine;

8. The automatic leveling function of the walking mechanism makes the drill rig more adaptable to the rugged mountain road in the mine;

The double-brazing mechanism guides the drilling tool throughout the whole process to prevent deflection during drilling (guide the impactor when opening the hole and guide the drill rod when drilling).
