YongJiu multifunctional pile driver is fully automatic top-hydrostatic pressure machine inventor of Zhang Weibin, who is the general manager of Zhangjiagang YongJiu Pile driver Engineering Development Co.,Ltd. And it’s another new machine through the new idea, also which is the most advanced international and domestic pressure to the machine. The aircraft in December 2001 after the State Patent Office identified as national patent products Patent No. 200610096931.1. Currently in Zhangjiagang YongJiu Pile driver Engineering Development Co.,Ltd. into mass production. It is the emergence of static machine history of the development of a major leap forward and innovation.
　Multifunction (BJY) new-type machine, which is set with set-hydrostatic pressure machine with the top-hydrostatic pressure machine advantages, removed, whichever is less than the perfect new product is a new, high-speed, safe and neat pressure machine, Not only is it small, but also functional, it will be able to fight side piles, piles, static-pile and the pile hammer, a multi-purpose, which is piles of modern construction machinery instead. And compared to the original static machine, it had increased the speed of piling, and had simplified the construction operations, enhance the construction of the security and reliability, saving the cost of the project. According to the pressure, it could be classified four grades: 150T, 200T,250T, 300T, and 400T.
　　1．Security : when the original Top of Pile Driver pressure pile is under construction, it needed to repeatedly lift heavy pile the pressure tank, and always hang in the air, which could bring operators of potential safety problems. But new static machine and the fuel tank is fixed, it could finished pile pressure through the extending of the rod, thereby ensure the safe operation. Also avoid piling pressure tank mechanical failure, the machine construction performance is more secure, and durable.
　　 2. Tubing: top pressure tubing machine work, it slid up and down, so it could be easily damaged because of frequent friction. And the new machine and asphalt pipeline system is basically fixed, there will not be any friction pipeline damage, so it declined so many situations, such as the pipeline vibration damage, oil spills and other phenomenon.
　　 3. Jointing pile: when the original Top of Pile Driver is at jointing pile, it could easily slide impact of sulfur clay splatter by burning constructors. But if new static machine is in that situation, the pile is under pressure steadily, then it couldn’t produce sulfur clay spatter, so as to avoid scalding incidents, protect the safe operation of the workers, steel joint operation with the same pressure machine.
　　 4. Rack loading : pressure machine with the original construction of the need reprovisioning lifting equipment, and to correction before the verticality under pressure, and the new machine to rely on their own rack loading, automatic vertical access to the center, to complete their own assembly, demolition, disembark. Crane counterweight, hoists piles, piles and so on the whole process.
　　 5. The construction speed and stop the use of time : The original static machine cheating must be a pile after pile-lifting another, and new hydrostatic machine in the same time lifting the piling under a pile, Pile, then pile, the pile driver to shorten the time to stop, improve the speed of construction.
　　 6. The transport ship the new machine is a combination of the type, in the transport, the main Rafah flatbed truck, the lengthening of Removable, poor soil conditions in the circumstances, at any time can be lengthened. When a piece of a transport vehicle may be confiscated without steam hoists with all its completion, thus significantly reducing the construction cost.
　　7. Rack : new static machine rack height of the fighting, none of the same length, than the original rack height of four meters lower, so that the whole machine structure is more compact, stable and secure reliable and easier to demolish, assembly, maintenance and transportation.
