ZGYX-420A / B / D hydrostatic DTH Drill Features: This type of drill rig to support power for the standard four-cylinder into Yuchai YD4D80, 30kW electric models. To configure three meters drill pipe is Φ60mm or Φ76mm divided into A, B two specifications. Subdivided into with dry type dust collector and enhance motor running models. 1, the aircraft structure to strengthen the intensity of each part, fully bear the functional requirements of the original drill ZGYX-3500 cars. 2, dual orbital motors drive and add shock turret, reducing the failure rate and the heavy volume of the original ball motor, while greatly strengthened Drill torque, making it more drilling aperture range. 3, the new housing design allows drilling vehicle maintenance very easy to use, strengthening drills aesthetics. 4, optional dry dust extractor unit, rock dust, more environmentally friendly, energy saving. 5, optional strengthen motor running, climbing more powerful, more reliable quality.
