• Introduction The MG-50AX anchor bolt rotary spray engineering drilling rig is mainly used for anchoring deep foundation pits in high-rise buildings, strengthening roadbed and dam foundations, preventing landslides, rock collapse and other disaster remediation projects, as well as single pipe and double pipe rotary spray pile construction, engineering survey hole construction, and can also be used for construction of highway guardrails, electrical force engineering electrical line pole holes, and small water wells.
  
  Main features ● The drilling rig adopts mechanical transmission and hydraulic feeding, and is a mechanical powered head type drilling rig. Drilling can be carried out at any angle from vertical to horizontal, or at an elevation angle of around 5 degrees.
  ● The power head of the drilling rig provides a long progress, with two types of travel: 2300mm and 1800mm, which is beneficial for improving drilling efficiency.
  ● The drilling rig mainly uses impact rotary (DTH hammer drilling) and rotary drilling methods, as well as spiral drilling, which is suitable for a wide range of geological formations and has high drilling efficiency.
