20m Drilling Depth Foundation Pile CFA Equipment/ Crawler type CFA drilling rig/ Crawler mounted machine
CFA Drillling Machine Max Drilling Depth 20 m And Max Diameter 1000 mm For Foundation Pile
Our CFA drilling equipment based on continuous flight auger drilling technique is mainly used in construction to create concrete piles.CFA piles continue the advantages of the driven piles and the bored piles, which are versatile and require no removal of soil. This drilling method enables the drilling equipment to excavate a wide variety of soils, dry or water-logged, loose or cohesive, and also to penetrate through low capacity, soft rock formation like tuff, loamy clays, limestone clays, limestone and sandstone etc, The maximum diameter of piling reaches 1.2 m and max. depth achieves 30 m, helping overcome problems formerly connected to project and execution of pilings.
Advantages:
1. Special hydraulic telescopic (TDP Series) crawler chassis and large-diameter slewing bearing are adopted for rotary drilling rig to meet super stability and transportation convenience.
2. Cummins electronic control turbocharged engine imported with original packaging is adopted, which has strong power and meets Euro III emission standard.
3. The hydraulic system adopts limit power control and positive flow control, which makes the hydraulic system more energy-saving and efficient.
4. The main winch with single row rope can effectively solve the problem of wire rope wear and effectively improve the service life of steel wire rope; the main winch is equipped with drilling depth detection device, and single-layer winding rope makes the depth detection more accurate.
5. Automatic control of the main winch lifting drilling tool matching concrete pouring, improve the pouring reliability.
6. The design of the whole machine meets the requirements of CE directive, and the safety is guaranteed and the construction is safer.
7. The standard centralized lubrication system makes maintenance more convenient.
8. One machine can be used for many purposes, and CFA construction method and rotary drilling method can be realized by changing the working device.
9.The main winch is lifted by quadruple steel wire rope to effectively improve the lifting force.
Automatic control of the main winch lifting drilling tool matching concrete pouring, improve the pouring reliability.
10. A variety of drill pipe configurations can be selected to meet the requirements of efficient construction in different formations.
