Excavator Mounted Hydraulic Vibro Hammer Excavator Pile Driver for Construction Projects

Hydraulic Sheet Pile Driver Hammer for Large Excavator

Pile driver, also called vibro pile hammer or high frequency hydraulic pile driver, can be used to drive piles into the earth or pull piles out of earth. It's widely used in construction and machinery.

Working Principle

1.  using its high frequency vibration to vibrate pile body with high acceleration,  the vertical vibration of mechanical produce will be passed 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.
2. then using the excavator down force, vibrating pile hammer and pile body weight to sink pile into the soil.
3. 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, type of pile and construction conditions,etc.
