It is the unique equipment of your jobsite to drive and extract sheet piles at any form for tight and/or deep constructions by use of vibration. It is powered by the excavator it is attached or by an external power unit, a power pack.
How Vibratory Hammer Works
OZKANLAR Vibratory Hammers consists of two major components, gear case and Clamp
The gear case contains eccentric weights, which rotate in a vertical plane to create vibration. The hydraulic motors mounted on the gear case drive the eccentric weights. The hydraulic motors and eccentric weights are connected to maintain proper synchronization. Only vertical vibration is created in the gear case, as the paired eccentrics cancel horizontal vibration.
The vibration created in the gear case is transmitted into the pile being driven (or extracted) by means of a hydraulic clamp attached to the bottom of the gear case.
A hydraulic clamp, bolted to the bottom of the gear case, transmits vibration to the pile attached. The clamp contains two gripping jaws; one fixed and one moveable. A hydraulic cylinder operates the moveable jaw to grip the pile firmly against fixed jaw.
The vibratory hammer is powered by hydraulic pressure directly from the excavator pump, so no extra external power pack is required.
Cushion Rubbers are used to isolate the vibration been transmitted to excavator.
Vibratory Hammers and Soil Conditions
Vibratory driving occurs relatively easily in non-displacement piles such as sheet piling, H-beam.
Granular soil (sand) The vertical vibration in the pile disturbs or "liquefies" the soil and causes the soil particles to lose their frictional grip on the pile. The pile moves downward under its own weight, plus the weight of the vibratory hammer. Amplitude of at least 3 mm is usually required to cause enough soil disturbances to achieve pile driving.
Cohesive soil (clay) The vibration will shear the soil from pile adhesion and allow the pile to move downward. Amplitude of at least 5 mm is usually required to cause enough relative movement to shear the soil away from the pile.
Pile Extraction Vibratory hammer is usually very effective, as the soil under the pile tip that resists driving does not have to be moved.
