1. Hydraulic dedicated chassis with low grounding pressure ratio;
2. Three point support for columns, two directional adjustment, high verticality of pile making;
3. High construction efficiency, no dead corners in pile positions;
Special hydraulic walking chassis design, with a smaller grounding ratio and adjustable grounding area according to needs, can better adapt to different working conditions;
This connection method is the first of its kind in China and a major highlight of our product, ensuring the safety of column lifting and the flexibility and reliability of column angle adjustment.
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 adjustment mechanism of slant support is driven by a lead screw, with high adjustment accuracy and superior self-locking performance.
