Performance Character of Changhe ZYB series Hydraulic Static Pile Driver
1) ZYB can drive piles more than 1200 meters a day with low noise
2) The unique design of hydraulic system leads to less energy loss and lower temperature rise during operation
3) Compared with tradiontal side-piling mechanism, ZYB side-piling mechanism increase its driving capacity by 30% -50%
4) Min feet contact area pressure ratio decreases by more than 15% , which makes ZYB unlikely to be caved into the earth.
5) The functions of pressure-maintaining and oil-compensating ensure that the oil pressure of clamping hydraulic system constant and avoid the event that the jaw sliding on the surface of the pile in the course of driving pile.
6) Pile-driving forces from the clamping box are drectly transferred to the clampers, avoiding the damage from the pile – driving forces to clamping hydraulic cylinders.
7) Because of being able to swing to be automatically adapted to the diameter and shape of pile, the clamping jaw and the pile can automatically keep full touch in the surface, as a result, the damage of pile is fully eliminated.
8) Because of monoblack clamping jaw and two clamping jaw which can only swing but can not move being used to located and guide piling, the pile can be kept fully parallel with the guide rail, as a result, the problem that the pile is slopingly drived and is easily sheared by traditional clamping mechanism has fully solved.
9) The oil filling system inlet in the hydraulic system makes oil tiling and filtering very convenient and free of pollution.
Patented Technologies of Changhe ZYB series Hydraulic Static Pile Driver
A. the patented pile clamping mechanism and its control system makes pile clamping reliable, keeps pile from being
damaged, and can allow thin-wall-pile be driven easily.1 set of clamping jaw is composed by 4 pieces of blocks, which are separately and directly driven by 4 pieces of oil cylinders in the clamping box. There are auto-swing mechanisms behind the clamping jaws. If clamping jaws don’ t hold the pile in the right way, auto-swing mechanisms can adapt the clamping blocks to keep full touch in the surface of pile. As a result, the damage of pile is fully eliminated.

B. We design a support pillar under every lifting cylinder. Therefore, lifting cylinders only supply the power of rise and down, avoiding its damage by steering force and lateral force during the movement of machine.

C. Two support pillars are moving on the same guide rail, and connected by a thick stick to prevent damage caused by the lifting pressure reply on one support pillar.

D. Outside-fixed Cantilevers are connected with the machine body by hinge axis. Its rigidity and strength is 30% better than insert cantilevers. After using the machine for a period, you’ ll find the gap between the insert joint of insert cantilevers become bigger and bigger.

E. The patented tech of multi grade control of pile driving velocity doubles the velocity.

F. The patented auto-reset mechanism ( two iron sticks) keeps the guide track of the short boat parallel all the time and protects the damage by unparallel.
