1. The column is supported at three points and adjusted in two directions. Its drilling verticality is better than that of the suspended track pile frame, and the verticality of the pile is higher;
2. Fully electric drive, low noise, no diesel combustion, no exhaust emissions, energy-saving and environmentally friendly
3. Flexible walking, high construction efficiency, and no dead corners in pile positions;
This connection method is the first of its kind in China and is also a major highlight of our product. While ensuring safer lifting of the column, the angle adjustment of the column is also more flexible and fast.
No shaking or deformation during lifting, 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 adjustment mechanism of slant support is driven by a lead screw, with high adjustment accuracy and superior self-locking performance.
