Application
HGD-600 sea exploration drilling rig is equipped with a top drive power head and comes with long feed travel. It uses a frequency changer to adjust the rotary speed and is equipped with 12 or 8m high derrick. It can be used to work under the condition of 80 m water depths and wind scale less than 5 grade. It is also used for water area geological exploration drilling and pile hole drilling in rivers or lakes. In addition, the drilling equipment can also be used for drilling pile holes on land.

Features
1) Equipped with a frequency changer, the sea exploration drilling rig can adjust rotary speed steplessly so as to ensure wide speed regulating range. Additionally, it features long feed travel and compact structure. Hence, the drilling machine can meet the demands of drilling in a great variety of complicated stratum.
2) Safety and reliable falling-resistant apparatus of top drive power head can ensure the safety of equipment and personnel.
3) Feed micro-adjusting mechanism of drilling machine can ensure both equipment and personal safety.
4) Our sea exploration drilling rigs can achieve mechanical demounting of drill rods using hydraulic apparatus. This reduces labor intensity and increases drilling efficiency greatly.
5) Moving top drive power head rearward offers the drilling rig a large space for drilling work and makes frequent hoisting and lowering of the drilling rod convenient.
6) Equipped with the advanced bottom sampling device, the drill rig can meet sampling demand in complicated stratum.
