Technical Specifications: KW350
Equipped Engine: Yuchai 92KW
Drilling Diameter: 140-325mm
Drilling Depth: 350m
KW350 model Multi-Function Geothermal Water Well Drill Rig is mainly used for drilling water wells ,ground source heat pump wells and other uses of the borehole. The rig can drill work on different Geological formations, drilling hole diameter is larger, the max hole depth of up to 350 meters.
Unique deep hole axial compression adjustable system to Adjust impetus, deep hole drilling reduces the rotation resistance. Have two-stage telescopic /shrink carriage, use 6 m drill pipe, reducing the times of change drill pipe.
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.
