Huitong Hydraulic Pile Hammers , also goes by Pile Driving Hammer, Vibro Hammer, are widely used in many big projects, suitable for all model of excavator.
Hydraulic pile driver is using its high frequency vibration to vibrate pile body with high acceleration to pass the vertical vibration of mechanical produce to pile which leading to changes in the soil structure around the pile, strength decrease. Soil around the piles become liquefaction to reduce frictional resistance between side of the pile and the soil. Then using the excavator down force, vibrating pile hammer and pile body weight to sink pile into the soil. When extracting piles, in the condition of vibration to pull out the pile by using excavator lift force. Excitation force needed by pile driving machinery are comprehensive determined by site soil, soil condition, moisture content and type of pile, construction.
AppliPCion: cast-in-place concrete pile, precast concrete pile, concrete expanded bore pile, lime pile, stone column. Beside, it's widely used in trestle work, cofferdam,offshore working platform, and also group pile or wind mill single pile.
