Rotary pile drilling rig is a kind of large-scale construction machinery, which is mainly used to drill piles in the foundation of buildings, bridges, roads and other structures.
Our rotary drilling rig working range is for 500~1500mm pile diameter and within 50meters depth, adopts pressurized drilling mode, high drilling efficiency, good pore-forming quality; equiped with heavy duty crawler chassis, reliable quality, flexible in construction, suitable for various pile foundation works.
SR-825 Rotary pile drilling rigs are widely used in construction engineering because they can drill deep holes quickly and accurately. They are often used in foundation engineering, bridge construction, high-rise building construction, and offshore engineering. In addition, they can also be used for drilling monitoring wells, anchors, and soil nails in geotechnical engineering.
1.SR-825 crawler type rotary drilling rig adopt pressurized drilling mode, enabling rotary drilling depth is 25m. matching the different specifications of drilling tools, pile hole diameter range up to 500-1500mm.
2.It has high drilling efficiency ,and After construction, It can quickly move to next worksite . flexible, convenient and efficient, is a national high-speed rail construction-specific piling machinery equipment.
3.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.
1.Flexible: the whole tonnage is small, simple operating, moving fast, convenient transition, etc features.
2.High returns: small investment, quick gains, economic advantages can not be replaced.
3.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.
