Rotary Piling Rig Machine SR-820 for 20m Pile Holes
Rotary piling rig machine 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 SR-820 rotary drilling rig working range is for 500~1200mm pile diameter and within 20meters 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.
Piling Rig Machine Application & Features:
SR-820 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-820 crawler type hydraulic rotary drilling machine adopt pressurized drilling mode, enabling rotary drilling depth is 20m. matching the different specifications of drilling tools, pile hole diameter range up to 500-1200mm.
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.
Advantages of Hydraulic Piling Rig:
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.
