1. The rotary head has unique designed seal that guarantees the slurry not to enter the case of rotary head.
2. Mast head of this piling equipment can be rotated so that the driving pipe can avoid opening and does not fall to the ground, thus reduces labor strength.
3. The hoisting cylinder can be used to replace winches. It has large hoisting force and is easy for maintenance.
4. The whole set of round pipes can be fitted on the base of the hydraulic drilling rig, which improves the mobility of the machine.
5. The extended length of the drilling pipes reduces the numbers of increasing pipes and improves the drilling efficiency.
6. Replacing the different drilling tools can make this piling equipment easily realize circulation and reverse circulation drilling.
