KW series multifunctional drilling equipment is mainly suitable for drilling water wells, agricultural irrigation wells and other wells, especially suitable for water intake projects in mountainous areas and rock formations. The efficiency is ten times higher than that of traditional rotary drilling rigs, and the economic benefits created for users are extremely considerable. In particular, it solves the difficulty of air DTH hammer drilling into the soil layer, and solves the construction problem of the rotary drilling rig in the hard rock layer, gravel layer, and pebble layer. It can work efficiently under various geological structures and realize the perfect combination of water drill and air drill.

The top-mounted driving head principal shaft has a great drift diameter, which is suitable for many kinds of construction work such as slurry drilling, air drilling, and air foam drilling, meeting the demands of well-drilling in different terrain strata.


Performance Characteristics

  • Engine: adopts the famous Yuchai brand turbocharged version engine.
  • Crawler Driving Gear: the designed motor with a speed reduction gearbox prolongs the service life.
  • Hydraulic oil pump: It uses parallel gearbox (which is a patent) to separate oil pump monomer, supply adequate power and distribute reasonable. The hydraulic system adopts unique design, which is easy to maintain and can lower the maintenance cost.
  • Rotary head device: integrated casting gearbox , dual motor power, large torque, durable, small maintenance costs.
  • Drill chassis: the professional excavator chassis provides durability and strong load capacity, the wide roller chain plate causes small damage to the concrete pavement.
  • Lifting force: patent designed composite arm with small size yet long stroke, double cylinder lifting, strong lifting capacity.
  • The lift arm is installed with a limiter to protect cylinder and ensure the safety of work.
  • Each hydraulic tubing is covered with a protective shell to effectively extend the service life of pipeline.
