• Introduction The YG-70 anchoring engineering drilling rig is developed based on the advantages of our company's YG series drilling rig. The performance parameters of the drilling rig are scientifically allocated to make it more suitable for rock down-the-hole hammer drilling and pipe following drilling, while also taking into account the rotary drilling and spiral drilling processes of soil alloy. The drilling rig has strong adaptability and can be used for multiple purposes. The drilling rig is a fully hydraulic driven power head type drilling rig. The hydraulic motor, pump, and quick connector of the drilling rig are made of international products, while other main components are selected from well-known domestic products to ensure stable, reliable, and long service life of the entire machine. The drilling rig can be used with various drilling techniques: conventional rotary drilling, DTH hammer impact rotary drilling, and casing following drilling.
  The YG-70 drilling rig is mainly used for anchoring engineering in landslides and dangerous rock masses in various geological disasters, especially suitable for anchor hole construction in high slope rock mass anchoring engineering. It is also suitable for various drainage holes, deep foundation pit support and foundation reinforcement holes, tunnel pipe shed support holes, blasting holes in blasting engineering, etc. With slight modifications, it can also be used for the construction of high-pressure rotary jet grouting piles.
  
  Main features ● The drilling rig structure is split type, with good detachablity and convenient relocation and installation speed; And it can be remotely operated, completing porous construction in one relocation; The operating staff have a good working environment and low labor intensity.
  ● The power head of the drilling rig has a high output torque, a long provision process, and high drilling efficiency.
  ● The output shaft of the drilling rig's power head is equipped with a telescopic mechanism, which can effectively protect the drilling tools.
  ● The direction of the power head and orifice plate can be adjusted to drill and chisel upward holes.
  ● The front of the drilling rig frame is equipped with up and down adjustable columns and huff, which can adjust the height of the mast, making the hole position quick and convenient during construction.
  ● The drilling rig is fully hydraulic driven and can achieve stepless speed regulation. It is easy to operate, time-saving, and labor-saving.
