Detailed Product Description

1.Application

HGD-600 sea engineering geological exploration drilling rig is a top drive power head type drilling machine with long feeding stroke. It adopted advanced technique of adjustable rotary speed frequency

changer 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. Main set of drill can be used for drilling pile

holes on land.

2.Features

1)Top drive power head of drill adopts frequency change

to adjust rotary speed steplessly. It features long feeding stroke, compact structure, rational arrangement and wide regulating speed range, with the result that drilling machine can meet the demand of drilling in a great variety of complicated formation.

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)Mechanization of break-out drill rods with hydraulic break-out apparatus reduces labor strength and increase drilling efficiency.

5)Moving top drive power head rearward integrally ensures large floor space and convenient for frequently hoisting

and lowering the drilling rod .

6)Equipped with the advanced bottom sampling device, it can meet sampling demand in complicated formation.
