The hydraulic static pile driver is a kind of pile foundation construction equipment with prosperous pared it with others,such as impact,vibration and infusion,it has the features as below ; The hydraulic static pile driver is 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 within a short-time. Excellent pjiling quality,100% pile-forming rate. Its expense cost isvery low in various construction methods according to the calculation for carrying capacity of precast pile per cubic meter. The lower stress of pile has less damage so that it can reduce the manufacturing cost of precast pile . It has the advantages of high mechanization degree,comfortable operation,flexible and convenient file foundation,easy to assemble and take apart. Civiliization,neatness,light labor,low noise,no vibration and no pollution. This machine is especially suitable working in inner city construction,so it is elgible to be a kind of ideal ecofriendly construction equipment. It's suitable to work under various geological conditions,such as collapsible loess,silty clay,sand layer,sedimentary gological strarificarion,full foundation and so on. New type clamping box with auto adjustable clamper devices prevent the concrete pile from damage,and ensur high reliability and low troubleshooting of clamping box.The service lives of clamping jaws have been prolonged at least twice after heat treatment technology was done.
