product Introduction

HF320 crawler type rotary drilling rig adopts pressurized drilling mode, enabling rotary drilling depth is 20m, matching the different specifications of drilling tools, pile hole diameter ranges from 400-1200mm. It has high drilling efficiency, and after construction, it can quickly move to next working site. Flexible, convenient and efficient, it is a national high-speed rail construction-specific piling machinery equipment.


  • 1Flexible: the whole tonnage is small, simple operation, fast moving, convenient transition, etc features.
  • 2High returns: small investment, quick gains, economic advantages can not be replaced.
  • 3Technology patents: patent uses a unique technology to achieve a small torque but big power characteristics, thus achieve a small machine to drill big piling hole.


This machine is applicable to soil, clay, fill soil, silt, silt layer, and some strata contain pebbles, gravel, widely used in high-speed rail trestle piles, slop shield piles, photovoltaic power station foundation pile, power grids, civil construction, new rural construction, municipal construction, landscaping and other projects.
