Hydraulic Pile Drivers

Product Description

It is the fastest pile-pressing driver in China and has a record of ***0m piling one day. 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. 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 . 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. It is the only pile-pressing driver in China which uses big oil-sucking-up pipe for oil sucking up and oil cooling. It is the only pile-pressing driver in China which uses alloy steel in body for large tonnage machine. It is the only pile-pressing driver in China which has a patent of accelerated pile-driving system . Optimal structure design according to theory of fatigue strength ensures the fatigue life longer than *5 years. 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 *0% which can prevent pile from being damaged by clamping jaw for too much jaw-clamping pressure . 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 *0% which ensures pile clamping reliable. 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 *0% and the max force born by body reduce *0%. 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 Special hydraulic pipeline and cooling system makes pile-pressing driver can work normally in any temperature. The close oil injecting and filtrating system makes oil injecting and filtering very convenient and be free from pollution. 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. 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 Φ**0 pile head ，the penetration-resisting ability is improved by about *0%. the crane of pile-pressing driver can hoist its long feet and short feet. Compared with others side piling mechanism, ZYB’s side piling system and body is a whole，this structure arises its strength and rigidity by *0%~*0% 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 *0%。Under the same counterweight condition，ZYB side pile driving ability raises by at least *0%. 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 *0% 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 **0 times cost to replace ball head base. 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 *0 times cost to replace the whole trolley. Compared with others hydraulic static pile-pressing driver in China, **0 model and **0 model of ZYB’s pile-pressing driver is equipped *0 ton crane，the capacity of crane increase by *0%.
