Dragon International Services and Development LLC series of high-frequency hydraulic vibration pile drivers are specially used with excavators to effectively utilize hydraulic power and dynamic components of excavator. Excavator has strong maneuverability and flexible operation characteristics, which brings pile foundation construction to new stage and greatly saves costs. Improve work efficiency, allow excavator to be used for multiple purposes, and improve investment efficiency. Hydraulic pile driver is powered by oil pressure. It can adjust hydraulic pressure according to different soil quality of stratum to achieve appropriate impact force for pile driving. Hydraulic pile driver pile driver consists of pile hammer, pile frame and ancillary equipment. Pile hammer is attached between two parallel vertical guide rods (commonly known as gantry) at front of pile frame and is lifted with a lifting hook. Pile frame is a steel structure tower with a winch at rear for lifting piles and pile hammers. Basic technical parameters of pile driver are weight of impact part, impact kinetic energy and impact frequency
