Hydraulic Static Pile Driver By Hunan Tianli Construction Mechinery Co.,ltd.

Technology features of Hydraulic Static Pile Driver:
Except for the general technology performances of the same grade products by domestic HSPD manufacturer, Tali pile driver is of yet some unique original technologies as follows.
1. Unique top-jacking design. Tali HSPD can be applied by not only clamping but also jacking or the two simultaneously. This mode can reduce the clamping stress effectively to avoid damaging the hull, especially of the thin-well pipe piles. (Patent No.: ZL02139875.7)
2. Original structure design of lifting leg. This features has changed the supporter of radial force from the lifting cylinder of pile driver during longitudinal walking. By this way, it is possible to avoid the damage of the lifting cylinder rod and the guide thimble, improving resistance to strain injury, impulsion, and weariness greatly. (Patent No.: ZL01249443.7)
3. Practical clamping mechanism. It can meet the needs of square pile, pipe pile and H-type steel pile only by changing the grippers. The grippers can adjust its orientation according to the pile surface to ensure enough contact to the pile, and to avoid pile damage.
4. Ingenious conception in the design of the border and corner pile mechanism. The border and corner piling force can reach 60%-70% of center piling force.
