HGD-200 sea exploration drilling rig is equipped with a top drive power head and comes with long feed travel. It uses a frequency changer to regulate the rotary speed and is equipped with a 8m high derrick.
It can be used to work under the condition of 80m water depth and wind scale less than 5 grade. It can also be used water area geological exploration drilling and pile hole drilling on river or lake. In addition, the equipment can also be used for drilling pile holes on land.
1) With a frequency changer, the sea exploration drilling rig can adjust the 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 equipment and personal safety.
3) Feed micro-adjusting mechanism of drilling rig can accomplish balanced drilling holes.
4) Our sea exploration drilling rigs can achieve mechanical demounting of drill rods using hydraulic demounting 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.
