Product Description

DF~H~2 Hydraulic Surface exploration drilling rigs is  a kind of light  rig designed for geological exploration  in remote area  difficult to enter.  It is mainly suitable for diamond drilling with wire line coring technique.  The rig consists of diesel power unit, hydraulic system,  control panel,  mast, main winch, wire linewinch, drill  head, feed  system, foot clamp, etc. The rig is completely hydraulic driven for all its surface coring function.Fission style design makes the rig in good assemble ability and disassemble ability, facilitating transportation tomost inaccessible areas. Robust structure plus exact control system ensures high penetration rate and outstanding reliability.


 Main Technical Features

1.  Full  Hydraulic and Drill Head model.  The drill  head rotation is realized with four hydraulic pumps driven by five diesel engines(has been advanced with Two larger diesel engines); this 
also makes the feeding hydraulic cylinder system relize its full stroke feeding in both higher and lower speed.

2. In good disassemblability. The rig is adopted  fission style in design, including  power unit, hydraulic  oil tank,manipulation platform and operation mechanism, i.e. the drilling section. So they are in light weight and can be carried by man power or animal power. The rig can be applied and performed in narrow space for drilling of hole at 45°-90° with stronger adaptability. 

3. Strong techniques adaptability.  Besides diamond drilling  with wire line coring  technique, it is in strong techniques  adaptability.  It is applicable for the drilling and feeding requirement of any other stratum.
