• Introduction The YSL-300 water well drilling rig is a fully hydraulic driven, power head type drilling rig. Mainly suitable for the construction of water well drilling machines, geothermal hole construction, and also suitable for the drilling and unloading of large diameter vertical holes in geotechnical engineering such as water electrical station engineering, railways, highways, and urban foundations; Grouting reinforcement holes; Small foundation pile holes; Micro piles, etc. Drilling machines use various techniques, such as conventional down-hole hammer drilling, long spiral drilling, mud circulation drilling, pipe following drilling, cone bit drilling, hydraulic hammer drilling, etc.
  
  Main features ● The drilling rig has strong drilling ability, a wide range of applications, fast drilling speed, strong accident handling ability, and high drilling efficiency
  ● The power head of the drilling rig can be mechanically/hydraulically variable. Suitable for various drilling methods such as DTH hammer, pipe following, full casing rapid alloy rotation, etc
  ● The spindle adopts a telescopic mechanism, which can effectively protect the drilling tools; The power head and orifice can be reversed to achieve a larger drilling angle
  ● The drilling rig is equipped with a hydraulic clamping and unloading device or a pipe twisting machine, which can automatically unload and reduce auxiliary time and labor intensity
  ● The drilling rig is loaded onto the tracked chassis, allowing the entire machine to shift and move more quickly and conveniently
  ● The main components of the hydraulic system of the drilling rig are all made of well-known domestic and foreign products, ensuring stable and reliable performance and long service life of the entire machine
  ● The drilling rig can be used with various drilling techniques:
  ● Non circulating liquid spiral drilling, air down-hole hammer drilling, mud positive circulation full casing drilling, air down-hole hammer following pipe drilling, roller drill bit drilling, etc
