KT15 Integrated Surface DTH Drilling Rig

Kaishan KT15 integrated surface DTH drilling rig is a new drilling device which is carefully designed for large open-pit mine based on our development and production of DTH drilling rigs for many years.

The drilling rig is hydraulically driven to complete walking, propelling, rotation and angle adjustment with strong power.

The drilling rig is equipped with high pressure screw compressor head and high pressure pneumatic hammer to generate high drilling efficiency; it is also equipped with hydraulic dry type dust collector to collect dust, so as to reduce pollution to the environment.

The drilling rig features good integrity, high level of automation, high drilling performance, environmental protection and energy saving, easy operation, flexibility and safe driving, etc.

Feature of KT15 Integrated Surface DTH Drilling Rig:

1. Promoting a length of 5 meters, effectively reduce the loading and unloading drill pipe and other auxiliary time, improve work efficiency;

2. Disc type auto rod-loading system is used and auto rod-loading can reach the depth of 35m.

3. Equipped with amplitude mechanism, the carriage has total swing angle of 130° (97° to the right and 33° to the left) to freely complete horizontal and vertical holes transition without changing pivot. The lowest elevation horizontal hole is 550mm and the highest elevation is 4,200mm.

4. It adopts Caterpillar electronic fuel injection engine to provide high power and reliable performance.

5. High wind pressure large-Capacity air compression system (22m3/min, 20bar) guarantees fast drilling of the hammer.

6. Automatic leveling function of the travelling mechanism enables the drilling rig to be more adapted to rugged mountain roads in the mine.

7. Double rod lifting mechanism guides the rig all the way to prevent deflection in the drilling process (It guides the hammer during trepanning and the drill rod during drilling).

8. The drilling rig adopts imported hydraulic parts and electric appliance.
