Exploration drilling rig HGD-300A

rotaryhydraulic

HGD-300A sea engineering geological exploration drilling rig is a top drive power head type drilling machine with long feeding stroke. It adopts the advanced technique of regulating rotary speed with frequency changer and equipped with 12 m high derrick and heave compensator. It can be used to work under the condition of 100 m water depth and wind scale less than 5 grade. It also used for water area geological exploration drilling and pile hole drilling on river or lake. The main set of drill can be used for drilling pile holes in land. Features ● Top drive power head of drill adopted frequency changer to adjust rotary speed steplessly. It features long feeding stroke,compact structure, rational arrangement and wide regulating speed range. With the result that drilling rig can meet the demand of drilling in a great variety of complicated formation ● Safety and reliable falling-resistant apparatus of top drive power head can ensure equipment and personal safety. ● Feed micro-adjusting mechanism of drilling rig can accomplish balanced drilling holes. ● Mechanization of breaking out drill rods with hydraulic break out apparatus reduces labor strength and increase drilling efficiency. ● Removing top drive power head rearward integrally ensures large floor space and convenient for frequently hoisting and lowering the drilling rod. ● Equipped with the advanced bottom sampling device, it can meet sampling demand in complicated formation.
