Special steel material with high ductility and high resistance It can be installed on the hydraulic excavator. The power is provided by the hydraulic pressure system on the excavator. The installment is easy with convenient and flexible operation It is driven by motor, utilizing a kind of exciting force produced by reciprocating motion of centrifugal force up and down. It effectively avoids hydraulic oil pollution and metal residue from damaging the excavatorâ??s hydraulic pressure system High efficiency, Mute, Used for piling and uplifting pile. Original imported motor, more durable, high swinging speed, higher torque, bigger and faster exciting force and frequency. All bearings are originally imported with longer life service. The shafts of all key part use the same material as module. With heat-treatment, the life service time is ensured. Different varieties piles like steel sheet pile, cement pie, steel pipe pile, round pile and square pile could be piled into the ground.
