1. Adjust the two directions of the column and ensure high verticality of the pile making;
2. Fully electric drive, energy-saving and environmentally friendly
3. High construction efficiency, no dead corners in pile positions;
4. High quality electrical accessories are used, and the main components are from internationally renowned brands.
This connection method is the first of its kind in China, and the adjustment of the column angle is more flexible and reliable; The column is adjusted forward and backward using an oil cylinder, which accurately and quickly locates the pile position and effectively improves construction efficiency
The lifting does not shake or deform, making it safer and smoother.
The unique sealing structure design of the power head can effectively prevent cement slurry from entering the gearbox body and extend the service life of the power head.
The support adjustment mechanism adopts screw transmission, with high adjustment accuracy and superior self-locking performance.
