Description
DTH drilling rig (down the hole drilling rig) is driven by pneumatic, electric or internal combustion engine. Crawler DTH drill rig features great grade ability, strong adaptability and stability. Allocated with different DTH impactor, this drilling rig is capable of drilling holes like blasting holes, anchor bolt holes and grout holes, etc. with different diameters, depths and directions, etc.

Advantages
1. Allocated with high pressure or medium pressure air compressor, DTH drilling rig features high speed drilling ability. It is capable of drilling 200 m to 300 m holes with diameter 115 mm.
2. The impactor is driven by high pressure compressed air, while the walking, rotating, propelling and positioning system are driven hydraulically, thus, crawler DTH drill rig can work with strength, safety and reliability.
3. DTH drilling rig is characterized by flexible operation performance, excellent cross-country power and high productivity.
4. Crawler DTH drill rig adopts air filter of world famous brand. Air compressor and diesel engine can share one air filter so that it can improve the working reliability and save maintenance time.
5. DTH drilling rig has dynamic walking function. Thus it is characterized by energy saving, high efficiency, low noise and low use cost.
6. Walking motor, main control valve and other key components are made by Germany and Jaapan manufacturers, which guarantees the reliability and usability of are from Germany and Japan.

Application
DTH drilling rig is applicable for extension rod drilling in quarry, railway, roadway, water and electricity, surface-mine and building engineering field, etc. Besides, crawler DTH drill rig can be applied to drill anchor holes, geological pressure measuring holes, drain holes and other rock holes with special purpose.

With quick development, production bases and representative offices are founded throughout the world, such as China, U.S.A, Germany, France, Japan, Holland and Belgium, etc. Bristol Compressors (Shanghai) Co. Ltd provides various air compressors, drilling rigs (such as DTH drilling rig and Crawler DTH drill rig) for sale in China. As a representative office, Bristol formally entered China in 2004.
