Crane Mounted Hydraulic Vibratory Hammer
Crane Mounted Hydraulic Vibratory Hammer
The vibratory hammer generates high-frequency vibration through the rotation of the eccentric blocks. The eccentric blocks appear in pairs, rotate in opposite direction, the transverse centrifugal forces counteract each other, and the vertical centrifugal forces are superimposed.
High-frequency vibration makes the soil liquefy instantly, and then the pile is plugged into the soil through self-weight and downward pressure.
Vibratory Hammer VS Impact Hammer
Vibratory hammer can not only drive pile but also extract pile. It is applicable for temporary protection works.
Hydraulic vibration hammer is piling faster than impact hammer, and less vibration and noise.

Application
It is usually lifted by the crane, and the hydraulic power is provided by a special power station. This is applicable for large construction projects with luge and heavy piles like marine pile driver.
