Pile Driver

ROCKA hydraulic pile driver utilizes its high-frequency vibration to shake the pile body with a strong acceleration. This causes the vertical vibration of the machine to transfer to the pile, resulting in changes to the soil structure surrounding the pile and a decrease in its strength. As a result, the soil around the piles becomes liquefied, reducing the frictional resistance between the pile and the soil.

To drive the pile into the ground, a combination of the excavator's downward force, the weight of the vibrating pile hammer, and the pile body's weight is used. When it comes time to extract the piles, the excavator employs its lifting force while the pile is still vibrating.

The amount of force required for pile driving machinery depends on various factors, including the soil conditions at the site, the moisture content, the type of pile, and the construction requirements.
