Rotary Type Drilling Rig for Foundation Construction

Drilling Rig, Mini Post Hole Digger, Water Well Drilling Rig  

1.  General Description

Nanjing Roadsky Traffic Facility Co., Ltd specializes in manufacturing Solar Crawler Screw Drilling Rigs and Truck-Mounted Screw Drilling Rigs. It has fast traveling speed and excellent performance, because of installing lifting steel ball motor and adopting chain-type hydraulic system. High torque of power output, high speed and efficiency of piling and pile extracting. This machine adapts to various soil, which can one-time complete when piling holes in pebbles geology, without secondary pound.

Self generating power and external connection power are both suitable for this machine, which makes wide applications to piling work of construction industry, highway, power construction areas etc. 

There are two series(ST Series, SC Series) of the machines, each series has two models, Trucked-mounted Screw Drilling Rig( ST1, ST2) and Crawler Screw Drilling Rig( SC1, SC2). You can choose according to your requirements. 

2. Specifications

3. Common Performance

Solar Screw Drilling Rigs is specially designed for piling work at WIND FARM, SOLAR and PHOTOVOLTAIC POWER GENERATION construction and etc. 

The piling diameter ranges from 150 mm to 800 mm while drilling depth from 1 m-15 m. The machine is equipped with 47KW diesel engine, which drives generator and output 40-50 kw power, which will:

 (1) drive the power head for rotation and drilling.

 (2) drive hoist for working with 7.5-11KW power;

 (3) drive the hydraulic system for working.

4.  Common Advantages

(1)High efficiency: Advanced technology in rotating drilling, no need to increase the load when drilling deeper, The power head has the characters of stable operation, high torque, high efficiency.

(2)Adapt to various ground condition and different geological conditions, meet a variety of construction requirements.

(3)Compact design, flexible operation and quickly moving are convenient for your works. You can choose the Truck-mounted or crawler-mounted models according to your requirements. 

(4)You can match with different screw drilling rods according to your requirements, the range of holes’ diameter is 150-800mm and the range of holes’ depth is 1-15m.

(5) The models are on the basis of excavator technology, facilitate the maintenance of the machine in the future. This rotary drilling rig has low center of gravity, very steady and safe for moving and working.

(6)Low investment with high return. Our rotary rig has the exquisite design, economical price, reliable performance, no need people to clean the soil, save lots of labor, it is the best choice to replace the manual hole digger and big pile drivers in certain ranges.
