Product Description

Kaishan KT20S integrated surface DTH drilling rig is a new DTH drilling rigs,it is a variant with a double drive (electric and diesel engines),air compressor with electric motor,hydraulic sytem with diesel engine and electric motor. 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.

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

2. 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.

3. It adopts Cummins electronic fuel injection engine to provide high power and reliable performance.

4. It is with a double drive (electric and diesel engines) significantly and reduce the use of cost.drill by electic motor with a cable drum,travel and operation by diesel eingine..

5. High Working pressure large-Capacity air compression system (31m3/min, 25bar) 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.
