1. With rather high speed and reasonable speed range with a few steps, high torque for low speed, it is suitable for small hole diameter core drilling of diamond mine, and also for large hole diameter core drilling of carbide alloy mine and various engineering drilling.

2. It has good drill capacity. With Φ71 wire-line drilling rod, it’s max. depth is 1000m.
3. It is not so heavy and is very easy to disassemble. It can be knocked down into 10 package units, with the heaviest unit weighing only 300 kg. Hence it is convenient for transport and adaptive to operation in mountain areas.
4. It features simple construction and reasonable layout. All the units are exposed outside without any mounted on top of another, so it is easy for maintenance and repair.
5. It has two oil cylinder feeding, length stroke (max. stroke is 600mm), for the sake of safety and labour-saving in handling any accident.
6. It is smooth in travel of the rig and can be fixed firmly. The frame is rigid with high stability in high speed drilling.
7. It is equipped with sufficient meters for indicating the conditions in the hole and with only a few operating handles for flexible and reliable operation.






 

Main application:

It can be widely used in the core drilling with carbide and diamond bits, engineering geological prospecing, the basic pile foundation engineering in large diameter, water well drilling, and exploring of shallow petroleum natural gas. It is compact in construction, rational in overall arrangement, moderate in weight, convenient in assembling and wide in range of rotation speed.
