HF320 crawler type rotary drilling rig adopts pressurized drilling mode, enabling rotary drilling depth is 30m, matching the different specifications of drilling tools, pile hole diameter ranges from 500-1200mm. 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.
Flexible: the whole tonnage is small, simple operation, fast moving, convenient transition, etc features.
High returns: small investment, quick gains, economic advantages can not be replaced.
Technology 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.
