Summary

Hydraulicstatic pile-pressing driver has already been widely applied in the precastpile construction of building foundation, bridge foundation,airport foundation,roadbed of railroads and trackless roads,because it can drive piles with rapid, no noise pollution ,no exhaust gaspollution and no mud pollution. Nowadays,many cities provide that it only allowed static pile-pressing driver to implement the pile foundation construction in the downtown,Hydraulicstatic pile-pressing driveris in process of replacement others traditional side-piling mechanism.

 

Since the beginning of 1990 year, the ZYB series hydraulic static pile-pressing driverwith 7 patents was succeeded in production by the Hydraulic Machine and Control Technology Research Institute of CSU which supports Changhe with its technology)。Today,ZYB series hydraulic static pile-pressing driverhas developed into the 13th generation “M” model, which can meet with the request of piling force from 80 to 1500 ton, the pile diameter is range from 300-1000mm,the square pile is range from 150-1000mm.Corresponding, the single pile loading ability reaches to 40~750 ton and is in the lead of international technology.

 

Main Performance

  1. It is the fastest pile-pressing driver in China and has a record of 1700m piling one day.

  2. It is the only pile-pressing driver in China which supporting cylinder is independent from supporting legs,consequently the supporting cylinder rod doesn’t need to endure horizontal force.

  3. It is the only pile-pressing driver in China whichdriving forces are directly transferred to the clamping jaw instead of clamping cylinder,so the service life of its clamping cylinder is increased more than several times .

  4.  It is the only pile-pressing driver in China which makes pile keep automatically parallel  with guiding rail and which four guiding rails are welded as a body in order to keep the four guiding rails parallel forever.

  5. It is the only pile-pressing driver in China which uses big oil-sucking-up pipe for oil sucking up and oil cooling.

  6. It is the only pile-pressing driver in China which uses alloy steel in body for large tonnage machine.

  7. It is the only pile-pressing driver in China which has a patent of accelerated pile-driving system .

  8. Optimal structure design according to theory of fatigue strength ensures the fatigue life longer than 15 years.

  9. Compared with other hydraulic static pile-pressing driver in China,the contact area between clamping jaw and pile increases over 1 time,The jaw-clamping pressure drop over 50% which can prevent pile from being damaged by clamping jaw for too much jaw-clamping pressure .

  10.  Compared with other hydraulic static pile-pressing driver in China,Changhe has reasonable special design of the clamping and pile-driving cylinder. Clamping cylinder effective working area is increased over 20% which ensures pile clamping reliable.

  11. Counterweight beam is on the outer side of the supporting leg cylinder,compared with counterweight beam inside of the supporting leg cylinder, the place for counterweight increase 40% and the max force born by body reduce 20%.

  12. ZYB series hydraulic static pile-pressing driver using pressure compensation type automatic variable pump  realizes constant power output, so there no working overflow power loss

  13. Special hydraulic pipeline and cooling system makes pile-pressing driver can work normally in any temperature.

  14. The close oil injecting and filtrating system makes oil injecting and filtering very convenient and be free from pollution.

  15. Compared with other hydraulic static pile-pressing driver in China,its rotary platform is about one meter longer,this can increase the steady of machine when the short-feet support the body.

  16. The structure of net-shaped rib in long feet and short feet guarantee that there are at least two rib in feet confront the pile head when feet stepped on Φ400 pile head ,the penetration-resisting ability is improved by about 40%.

  17. the crane of pile-pressing driver can hoist its long feet and short feet.

  18. Compared with others side piling mechanism, ZYB’s side piling system and body is a whole,this structure arises its strength and rigidity by 30%~50%

  19. Compared with other hydraulic static pile-pressing driver in China, the distance between ZYB’s side piling center and the nearest supporting leg reduces  by at least 50%。Under the same counterweight condition,ZYB side pile driving ability raises by at least 20%.

  20. Oil pump station is positioned within working range of crane. Compare with the oil pumps station positioned under operation cabin,the maintaining service time for oil pump station is reduce 80%

  21. Compared with bifid ball head gland and connection by bolt and tapped hole in ball head base used in other hydraulic static pile-pressing driver in China,ZYB use integral ball head gland and connection by bolt and nut。Firstly,it can avoid ball head jump from the ball head gland;Secondly,it can avoid  the damage of ball head’s tapped hole in ball head base, it needs spend 300 times cost to replace ball head base.

  22. compared with the whole Walking trolley with the axles and trolley carrier welded as a whole used in other hydraulic static pile-pressing driver in China,ZYB’s axles is movable from trolley carrier. If the axles is damaged,it need to only replace axles,rather than to spend 10 times cost to replace the whole trolley.

  23. Compared with others hydraulic static pile-pressing driver in China, 680 model and 800 model of ZYB’s pile-pressing driver is equipped 20 ton crane,the capacity of crane increase by 20%.

     

Patented Technology

1. The patented pile-clamping mechanism with function of clamping jaw automatic aligning and swing, make the position of clamping jaw adapt to different size and position of piles by itself, minimize damage to the piles. The pile-driving force is directly transfer to clamping jaw from the clamping box, in order to keep the pile clamping cylinder from being damaged by the pile-driving force.

    

2. The patented long-feet-moving mechanism directly driven by double carts prevents the lifting mechanism from easily being damaged by enduring double horizontal force.

 

 3. The patented cantilever articulatingmechanism has the rigidity and strength 30% higher than traditional plug-in cantilever, making the machine more stable to operate and more convenient to transport.

 

4. The patented lifting mechanism with protective sleeve(machine above 420t) or upside down(machine below 360t) prevents piston-rods of cylinders from enduring horizontal forces and consequently brings them longer operating life.

 

5. The patented multi-grad control of pile driving velocity doubles the piling speed..

 

6. The patented auto-replacement mechanism of traverse and rotary motion automatically keeps the rails of the short feet being parallel all the time and protects the machine from being damaged.

7. The patented pile-clamping mechanism with clamping cylinder axial driving and replacement of radial spring, makes 8 clamping jaw structure come true and more reliable. Every two basic tubular jaws drive one square jaw with a replacement of radial spring, aiming at clamping the square pile. The pile-driving force is directly transfer to clamping jaw from the clamping box, in order to keep the pile clamping cylinder from being damaged by the pile-driving force.
