THE CHARACTERISTICS OF YZY SERIES PILE DRIVER: The hydraulic static pile driver is pile foundation construction equipment with prosperous future. Compared it with others, such as impact, vibration and infusion, it have the features as follows. 1.Civilization, neatness, light labor, low noise, no vibration and no pollution. 2.High efficiency and high piling rate with pressing pile 300-800meter within 8 hours. It has been a powerful machine to finish a large-scale foundation project with large area and short-time. 3.Excellent piling quality, 100% pile-forming rate. 4.Its expense costs is very low in various construction methods according to the calculation for carrying capacity of precast pile per cubic meter. (The costs is nearly as much as driven cast-in-place pile when the carrying capacity is the same as precast pile.) 5.The lower stress of pile has less damage so that it can reduce the manufacturing cost of precast pile. 6.It has the advantages of high mechanization degree,comfortable operation ,flexible and convenient file foundation, fast dismounting and fry ferry.
